That's Bats!

And now for something much lighter and completely different. If it isn't to your tastes, please skip to the note at the end of the post.

There are all kinds of intriguing zoological references in this week's parashah. One is our old friend the hyrax (and there is a free chapter on the hyrax from my forthcoming encyclopedia available at this link). Another is the atalef, listed at the very end of the list of non-kosher birds. The general consensus of both Jewish tradition and modern academic scholarship is that the atalef is the bat.

Some people get very worked up about the fact that the bat is a mammal rather than a bird, which they perceive as a conflict with the Torah's divine authority. Now, while various rabbinic authorities have pointed out that the Torah is not always scientifically accurate, this case does not fall into that category. There is no “right” or “wrong” method of classification. A system of classification has no independent reality. It is simply a means by which we measure and describes the animal kingdom, depending upon our purpose. For the purposes of science, the animal kingdom is evaluated on its own terms, based on anatomy. For the Torah’s system of classification, the animal kingdom is presented in terms the relationship between animals and human beings, and their perception by the common person. Neither system is more correct than the other; they are just serving different purposes. In the Torah, anything birdlike is classified as ohf - including bats. This is not a scientific error, just a different system of language.

The Gemara, on the other hand, is another matter. In a curious passage, with no apparent halachic or hashkafic significance, it states as follows:
Everything that bears live young, nurses them, and everything that lays eggs, gathers food for its young, except for the atalef, which, even though it lays eggs, nurses its young. (Bechoros 7b)
In contrast to the Talmud’s statement, modern zoology asserts that none of the 950 species of bats lay eggs, and further asserts that there was never an egg-laying bat. An egg-laying bat would be completely contradictory to the neat nested hierarchy of the animal kingdom - and amongst all the millions of known species, no such exceptions have ever been found.

Could the Gemara be referring to something other than a bat? Rabbi Joshua Waxman has presented a fascinating argument that the Gemara is referring instead to a species of owl known as the stryx, which does lay eggs, and was believed to nurse its young on milk. But, as Rabbi Waxman notes, this would still not make the Gemara scientifically accurate, since owls do not nurse their young.

Rabbi Moshe Meiselman, who insists in his book Torah, Chazal and Science that every definitive statement in the Talmud must be correct, and further insists that to say otherwise is heresy, takes a different approach regarding this statement about the atalef. Before the book was published, I predicted that Rabbi Meiselman would fail to address this Gemara. I was wrong - he addresses it at length (chapter 24). The reason why I did not think that he would discuss it is that I couldn't conceive of any way in which he could reasonably claim that the Gemara is scientifically correct. (See if you can spot the false assumption that I made.)

Rabbi Meiselman discusses this Gemara. And he argues that it does not present any scientific problem at all. He claims that the atalef is... the platypus.

No, I am not joking. Rabbi Meiselman claims that the atalef is the furry, mammalian, four-legged, web-footed, egg-laying, duck-billed platypus of Australia. He comments (p. 337) on the wonder of Chazal knowing about the duck-billed platypus: "In their day no one had ever seen one, nor could the Rishonim have imagined them; but Chazal knew that somewhere in the world they must exist."

Rabbi Meiselman acknowledges that this goes against the identification of the atalef given by the Rishonim. But he dismisses the Rishonim as having an inadequate mesorah and mistakenly understanding matters in light of the flawed science of their era. It is not clear to me why he considers this perfectly acceptable to state with regard to the Rishonim, but heretical to state with regard to Chazal. 

To support his claim that the atalef is the platypus, Rabbi Meiselman argues that it doesn’t make sense to claim that the Gemara is repeating an erroneous belief that bats lay eggs, since this Aristotle and Pliny recognized that bats do not lay eggs. Yet this is hardly sufficient reason to prefer the platypus. Chazal were not always in sync with Greco-Roman views - unlike the Greeks, they did not know that the sun passes on the far side of the earth at night. A Google search for "do bats lay eggs" brings many thousands of results, revealing that even in the scientifically-literate 21st century, there is much popular confusion about this matter - certainly such a belief would have been vastly more widespread in antiquity. (Also, as noted above, the Gemara may have been referring to a bird that was believed by the Greeks to lactate, rather than to an egg-laying bat.)

Rabbi Meiselman further argues that Chazal not have mistakenly believed that bats lay eggs, if they observed them closely enough to know that they nurse their young. But even close observation of bats nursing would not lead to the conclusion that there are no eggs, just that one had not discovered them yet. Furthermore, in any case there is no need for close observation to conclude that bats nurse their young - one can just draw this conclusion from its generally mammalian physiology.

Positing that Chazal believed in egg-laying bats (as many people still do) or lactating owls (as was common in antiquity) is infinitely more reasonable than proposing that they knew of the duck-billed platypus! How could they have known of the existence of the platypus? Rabbi Meiselman vaguely asserts that they knew it from "their understanding of the spiritual underpinnings of the world." He does not explain how understanding the spiritual underpinnings of the world leads one to conclude that there is a duck-billed platypus. Additionally, as discussed at length in my monograph on Sod Hashem Liyreyav, there is scant traditional support for such a notion. Furthermore, if their understanding of the "spiritual underpinnings of the world" was not sufficient to enable them to realize that the sun passes on the other side of the world at night rather than doubling back behind the sky, it is rather unreasonable to propose that it was sufficient to enable them to decipher the existence of the duck-billed platypus.

(UPDATE: Note that Rabbi Meiselman does not claim that they knew specifically of the platypus. Rather, he claims that they knew that there must be another creature which, like the bat, has characteristics of both birds and non-birds. He also claims that they knew that this creature must have a different combination of those characteristics than bats do. Rabbi Meiselman provides no support for either of these two extraordinary assertions. Furthermore, if they knew that there must be other animals with other combinations of bird/non-bird characteristics, why limit it to a mammal that lays eggs? By this logic, there must also be a fish with feathers and an amphibian with a beak!)

But there is another powerful reason why Rabbi Meiselman's case is absurd. He is not arguing that the atalef of Scripture is a platypus, because that is listed amongst the category of ohf. So he argues that Chazal used the same name as the atalef of Scripture, which he agrees is probably a bat, yet here referred to a different animal. But consider how astonishingly misleading this is making Chazal out to be. Instead of giving the platypus any kind of unique name or description and informing us that it lives in Australia, they chose instead to use a name that the Torah uses to refer to a creature that also has mixed characteristics of mammals and birds, the bat, thereby misleading every student of the Gemara for the last 1500 years to mistakenly believe that they were talking about the same creature!

(Furthermore, if Chazal knew of the exceptions to the rule that egg-laying animals don't lactate, why didn't they mention the echidna, pictured at right?)

So, Rabbi Meiselman prefers to posit that Chazal were able to figure out the existence of the duck-billed platypus, which they misleadingly referred to with the same name as the bat, rather than positing that just as Chazal subscribed to the ancient belief that the sun travels behind the sky at night, they likewise subscribed to the widespread belief that bats lay eggs.

In perhaps the most remarkable twist of logic, Rabbi Meiselman concludes that “the very case that people cite as a challenge to Chazal is actually another demonstration that their knowledge was derived not from contemporary wisdom but from Torah itself.” But Rabbi Meiselman has not in any way proved that they actually derived this view from Torah. Furthermore, the issue is whether their knowledge is divinely correct, not where they derived it from. Chazal derived aspects of their understanding of the heavens being solid from Scripture, but this does not mean that it was correct!

Personally, I think that Rav Hirsch's approach, which is very well-founded in Chazal, the Geonim, the Rishonim, and the Acharonim, is the only reasonable explanation. According to this approach, there is no "problem" here, per se. "Chazal were the sages of God's law - the receivers, transmitters and teachers of His toros, His mitzvos, and His interpersonal laws. They did not especially master the natural sciences, geometry, astronomy, or medicine... we do not find that this knowledge was transmitted to them from Sinai." Thus, Chazal were simply relating an ancient and erroneous belief that bats lay eggs (or that owls nurse their young). Presenting this approach to the Gemara does not diminish the honor of Chazal. And nor, unlike the platypus claim, does it diminish the honor of the one presenting it.

  1. Kol hakavod! I would just point out, though, that to identify the atalef as two different animals is not per se absurd. In Lev. 11:30, the tinshemet is listed among the birds, but appears again in Lev. 11:30 among the reptiles. What is unconvincing is to claim that Chazal's atalef was a creature found only in Australia, or (as has been suggested) that both instances of "tinshemet" refer to the archaeopteryx, which was extinct a rather long time before the Torah was given and would not likely have tempted the Dor Ha-Midbar.

  2. Sabi, certainly different animals can have the same name, as per the atalef, and Chazal can certainly use a name differently from Tenach, as with the re'em. However, in this case, when Chazal are talking about a creature that is unknown to any of their students, it is absurd to posit that they would use the exact name of a known creature that people would clearly think that they were referring to.

    Actually, it isn't completely different.

    In a community where a book like Torah, Chazal and Science is championed for its brilliance and professional expertise, despite it being full of dishonest rabbinic scholarship, scientific ignorance, and batty claims, it is no surprise that specious arguments about yeshivah students being exempt from military service are presented with the insistence that nobody may challenge them.

  4. "An egg-laying bat would be completely contradictory to the neat nested hierarchy of the animal kingdom." -- Hey, I remember that exact line from your excellent book Sacred Monsters. Heh, you're entitled to recycle.
    But I'm not sure just how "neat" it is. Yes, it's neat for the most part. But there are some irritating exceptions, such as can be gleaned here:
    http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0040352
    When Carl Woese, the noted microbiologist, writes that: "phylogenetic incongruities can be seen everywhere in the universal tree, from its root to the major branchings within and among the various taxa to the makeup of the primary groupings themselves", it causes me to hesitate accepting the term "neat."

  5. >> A system of classification has no independent reality.

    This statement needs qualifying. People argue about systems of classification but the prevailing view amongst biologists as I understand it is that classification is cladist, like branches on a tree and reflects evolutionary relationships. As such it does have an independent reality.

  7. Mr. Messy,

    Systems of classification are conventions that are made up for convenience. While the biologists system of Phylum, Class, Order, etc. makes lots of sense for classifying animals it doesn't help much for hilchos tuma and tahara and issur and heter.

    It doesn't differentiate, for example between what the Torah refers to as Chaya - cheilev is muttar and Beheima - cheilev is assur.

    It doesn't differentiate between flying creatures that we are permitted to eat and flying creatures that we are not permitted to eat.

    That's why Chazal categorized differently based upon common denominators for those animals that are muttar and those that are assur.

    Example - flying creatures that are assur are all dorsim (with possibly one exception.)

    Chazal's system of categorizing works better for its purpose that science's.

    Your last paragraph asking for financial assistance brought a smile to my face.
    Some people ask for financial assistance for writing a blog that is Mevaze Talmidei Chachamim, others ask for financial assistance for delving into the Ketzos.
    I leave it to your readers discretion as to where they feel their money is better invested.
    On a similar tone some people go against the norms of traditional jewry and sit and learn Torah the whole day while others go against the norms of traditional Jewry and publicly name & shame the Ziknei Hador to the whole world.

    I'm not asking for "financial assistance," I am asking for hakaras hatov for a service rendered. Obviously, if you feel that exploring rationalist Judaism and its perspectives on contemporary society are nothing more than "mevazeh talmidei chachamim," then you won't be feeling any hakaras hatov - but if so, why are you here?

  10. This is a terrific post. I read R' Meiselman's book -- all 800 pages of it -- and found it to be intellectually dishonest from beginning to end.

    I agree that Torah-true Jews can totally rely on Rav Hirsch, and that is what I learned from my father z'l.

    PS This wiki entry on "crop milk" may be relevant to the question of whether Chazal could have known of a bird that lays eggs and "nurses" its young. No stranger than the hyrax doing something that outwardly resembles "chewing its cud":

    http://en.wikipedia.org/wiki/Crop_milk

    "Crop milk is a secretion from the lining of the crop of parent birds that is regurgitated to young birds. They are found among all pigeons and doves where they are referred to as pigeon milk. Crop milk is also produced by flamingos and some penguins."

  12. I would add that Chazal's statement about bats, while embedding a common misconception, was actually correct in some sense. Bats really are flying animals that nurse their young (since they are actually flying mammals). In that they are exceptional, although they don't lay eggs. By reinterpretation to some statement about a Platypus, you are not increasing the honor of Chazal, but actually interpreting away a correct observation.

  14. The Shabbat section of the Makor Rishon newspaper (highly recommended for people who follow this blog...it is one of the premier journals in Hebrew for discussing the same kind of issues that are explored here) had an interview with a leading "modern Haredi" who came form a hard-line Haredi family but he decided to get law degrees and to go clean-shaven. However, he still considers himself Haredi and tries to explain how these modern Haredim are trying to maneuver and still be part of the Haredi world, even though they may not be true "Torah Jews" as they see it. It is clear they do not have a clear ideological base and are riven with contradictions in their attempt to remain true Haredim, even though they work and they may want to participate in "Israel culture". Guilt feelings about not studying full-time may lead to increasingly extreme views regarding ideological issues such as the ones raised here. In the last election, UTJ politicians managed to convince these people to vote UTJ and not for the "Tov" party, but the fissures remain, it will be difficult for the Haredi leadership to sanction what the New Haredim do for fear of losing those who make major sacrifices to keep studying full time.
    Thus, although many believe this "New Haredim" phenomenon indicates a moderation among many Haredim, I can see how it does not really signal this. Sicherman himself says he doesn't view it as such, but rather it is simply focussing on "parnasa" but not on other factors of Haredi identity.

    Surely you have put the strongest evidence to your hypothesis as an aside to your post.

    The quote from the gemorah states that the *only* exception to the rule is the atlef. Whether we accept R' Meiselman's claim that they were referring to the platypus, assume you are correct that they were referring to the bat, or even believe that there was some other now extinct or unknown creature (batlike or otherwise) that they were referring to, we can clearly see that Chazal were *not* aware of all the necessary science to back up their claim, as in fact the claim is untrue! There are actually at least two exceptions to the rule that we know of while Chazal stated that there is only one exception!

    You, and many others, equate "atalef" to bats. yet, if you look in Rashi, this becomes problematic because Rashi equates "tinshemes" that is mentioned by the flying animals with bats! Look in rashi and how he translates it in (old) french: he writes it is "chauve souris" which is the Frecnh word for a bat.He further explains that it looks "like a mouse that flies at night"! Exactly what it is!
    The 'tinshemes' that is mentioned by the "sherotzim', (little animals), he equates to the mole ( 'taupe" in French).
    Rashi does not say what the Possuk means with "atalef'.
    So,although Rashi clearly includes bats in this classification, it is under "tinshemes",not "atalef"

    Rashba does not say that it is wrong to ever attribute scientific error to Chazal, as I shall discuss in a future post.
    Furthermore, even if Rashba and a dozen other authorities were to say that it is wrong to ever attribute scientific error to Chazal, this would not negate the dozens of other authorities who do attribute scientific error to Chazal.

    The false assumption you made (and make) is: 'If I have no explanation then there IS no explanation.'

    No, the false assumption that I made was that Rabbi Meiselman would limit himself to reasonable explanations. I had thought of the platypus approach, but never dreamed that he would actually use it!

It is that the spiritual underpinnings of the world lead to the understanding that some creature included in the category of ataleif has these unique characeristics. After demonstrating that in the Torah one name may refer to entirely different species in different places, he explains at length why the bat and the platypus might be included in one category, thus sharing a name.

    "He does not explain how understanding the spiritual underpinnings of the world leads one to conclude that there is a duck-billed platypus.”

    Well, of course not. Does anyone in this generation claim sufficient mastery of Torah to understand the spiritual underpinnings of the world? The question here is whether such an understanding may be attained by people whose mastery of Torah was much greater and deeper than our own. The Ramban and other Rishonim clearly state that it may, as Rabbi Meiselman demonstrates at length in an earlier chapter of the book.

    The Gemara is not intended to be a book on zoology. It is Torah shebaal peh.

    After expressing doubt regarding the correctness of his explanation, he points out that IF his explanation is correct, it would demonstrate that Chazal’s knowledge was not derived from contemporary wisdom etc. He does not present this as a proof that this statement of Chazal, or his understanding of it, is correct, but as a demonstration that:

    “whether one assumes a priori that intriguing cases such as the ones we have looked at are irresolvable or that a solution- perhaps an interesting and enlightening one- awaits to be found is simply a matter of the perspective with which one approaches the words of our Chachamim.”

  26. Rabbi Meiselman's leap of reasoning is quite extraordinary:

    1) The Torah lists a creature, the atalef, which is the bat, in the category of Ohf.

    2) The bat is an Ohf, but it has characteristics of mammals.

    3) There must be other creatures that are in the same category.

    4) The particular shared characteristics of these creatures
    must be different from those of the bat.

    Items 3) and 4) are entirely unsupported assertions. Furthermore, his whole claim is that there must be other animals that fall in the same class as bats. But the bat is an ohf with mammalian characteristics, whereas the platypus is a chayah/sheretz with avian characteristics.

    And why were Chazal insistent that there must be a chayah that lays eggs? By this logic, there must also be a fish with feathers and an amphibian with a beak!

    R. Meiselman also has to explain away or insist to be forgeries the Rambam, Rav Avraham Ben HaRambam, Rav Sherira Gaon, Rav Shlomo Zalman, Rav Herzog, and then ignore Rav Hirsch. In fact, in two places, he is forced to explain away the words of his own Rebbi, the Rav.

    He is also relying, in part, on a Rashba on Treifos which Rav Moshe insisted that the Rashba would have retracted and in fact has retracted in Olam HaEmes.

    Even R. Feldman, who now opposes R. Slifkin, has said that there exists a Shita in the Rishonim that the sage could err in science.

    He also admits that the "definitive statement" is ill-defined and only an expert can tell which statements are definitive and which are not.

    R. Meiselman's thesis is less than "rock-solid". Stay tuned, as I'm sure that these arguments will be further addressed here.

    So, the gemoro is not intended to be a book in zoology. Presumably, then, it is not intended to be a book on astronomy, or a book on human functions, or a book on natural phenomena...etc. Why, then, do we accept anything in the gemoro to be factual? Why should we tak ANYTHING in the gemoro at face value? Taking this approach, we can say that any chazal is allegorical-clearly a position the writer would bristle at accepting. It is an absurd opinion to espouse, as the writer would have us choose and twist what chazal meant and, of course, leave only in the hands of those he agrees with to be the genuine explanation.
    As an aside to an earlier commment, Rashi in bechoros does call "atalef", the "chauve souris" (bat) that he calls "tinshemes"' in Shemini. ould like to hear from all fundamentalists how they explain this clear contradiction in Rashi's.

  30. Natan - I stumbled on this Gemara in Chullin (60a), which appears to support a non-rationalist Torah/science approach. I'm curious what you think:

    "R. Hanan b. Raba said: The shesu'ah11 is a specific creature that has two backs and two spinal columns. Was Moses a hunter or an archer? This refutes those who maintain that the Torah was not divinely revealed."

  33. "R. Meiselman also has to explain away or insist to be forgeries the Rambam, Rav Avraham Ben HaRambam, Rav Sherira Gaon, Rav Shlomo Zalman, Rav Herzog, and then ignore Rav Hirsch. In fact, in two places, he is forced to explain away the words of his own Rebbi, the Rav."

    The Rambam, as far as I know, has not weighed in clearly one way or the other on the specific question of whether one is permitted to conclude that Chazal erred in a matter of science. Regarding Rabbeinu Avraham ben HaRambam, Rabbi Meiselman doen not simply "insist" it is a forgery. He presents ample evidence. Although the responsa attributed to Rav Sherira Gaon (the attribution is not entirely clear, as R. Tuvia Katzman of Machon HaTalmud points out) regarding Chazal's medical advice does, at first glance, seem to contradict the Rashba's approach, it may be squared with the Rasba's approach, and there is solid basis internal to the sugya to do so (i.e. the Rashba himself seems to distinguish between Chazal's medical advice and all other statements about the world.) Rav Shlomo Zalman simply relates to the existence of Rav Sherira Gaon's responsa. He does not present it as normative even within the realm of medicine, and does not discuss its relevance to non-medical statements of Chazal. So essentially, Rav Shlomo Zalman is not an indepedent source on this question at all. Regarding Rav Soloveitchik, I do not know what you are referring to. (If you mean the question of evolution, it is not relevant to this discussion).
    A clear statement from the Rashba against the far-from-clear statement of (maybe) Rav Sherira Gaon, is no contest in the halachic realm, especially when that position of the Rashba is supported by the Rama, Maharal and many other early Acharonim. Rabbi J. David Bleich, known for his encyclopedic knowledge of halachic sources, has written that one would be hard pressed to find any classic source besides the Pachad Yitzchak who holds that Chazal's statements about the world may be considered mistaken. Rav Hirsch and Rav Herzog, chashuv as they were, do not impact on this equation.

    First of all, if this statement strikes you as extraordinary, then you have probably never read Rabbi Meiselman's book. No one has claimed that the purpose of Gemara is to serve as a science book, (or even that a great deal of scientific knowledge is contained in the Gemara.) On the other hand, when the Gemara does make statements about the world, they may NOT be treated as incorrect or irrelevant, because they are part of Torah Shebaal Peh.

    When the Gemara makes a statement about the characteristics of the ataleif,it may reasonably be assumed that the Gemara's purpose is not to inform us of some random zoological factoid. It is very possible that it telling us that in the metaphysical scheme of things, a creature in the category of ataleif must have these characteristics. The specific identity of the creature, in this context, is secondary, and might therefore not be elaborated upon. (The Gemara's language is often extremely terse.)If the statement was one of practical halachic relevance, then its actual identity would be of primary importance, and would presumably be identified clearly.

    3) "The atalef of the gemara is the platypus, and not the same as the atalef of the chumash" is not a remotely reasonable explanation, as the gemara gives no indication that it is talking about a "different atalef", which it would be expected (and required) to were that actually the case.

    It's not a matter of whether a common name can be justified (cf. tinshames). The point is that if they want to communicate that they were talking about an animal that was NOT the atalef of the Torah, and that nobody had seen or knew about, then it wouldn't make sense to call it "atalef" without any further qualification. Not sure why you fail to get this point.

    But the bat is in the category of atalef and does NOT have these characteristics. So even with your imaginary metaphysical approach (completely contrived and not even hinted at by any Rishon), the Gemara would be telling us that there is something that has DIFFERENT characteristics than the atalef of the Torah. In which case, it would have to call it anything in the world aside from atalef!

    OK. You can come up with a "chiluk". But a "chiluk" has to be substantial in order for it to be relevant. Now let's see. Rebbi says that a two-headed person can't possibly exist, and to make his point clear he expels the questioner from the בית מדרש. Now, are we to believe that Rebbi's statement was tentative? That he would put someone in cherem based on a conclusion that was not definitive? Of course his statement was definitive!

    "Part of the definition of "definitive" in this context is "conclusive", i.e. it is the conclusion of the Gemara."

    So what exactly are you saying? Chazal did utter definitive statements about the
    natural world that were incorrect. However, when those statements are recorded by the Gemara as a conclusion, they acquire the status of infallibility? Wouldn't that imply that the post-Chazal generations and/or the Savora'im had greater רוח הקודש than Chazal themselves?

    But once you acknowledge naar ivri's point, this major component of the critique dissolves.

    Again, Rav Meiselman explicitly did not use this novel solution as any kind of "proof" that Chazal "knew" about the platypus 1500 years ago. But the term atalef happens to be the best way to describe it using Chazal's method of animal classification.

    If you can't see why Rav Hirsch and Rav Herzog's opinion are not relevant in the face of this list of Geonim and Rishonim, I'm afraid there is no appreciation of vastly different levels of authority in Jewish scholarship on the other side of this discussion.

  46. Ephraim hits the nail on the head with regard it comes to R. Meiselman's theory. Chazal cannot make definitive statements because Chazal is not a person. Individual members of Chazal made definitive statements and they were often "wrong" (by R. Meiselman's definition of wrong), not the least of which because there were at odds with the words of other members of Chazal.

    Truly astonishing. So now, Chazal were using the name of a creature not to refer to a creature (as is the case every other time a creature is named), but instead to refer to a "generic, abstract sense"!
    And this "generic, abstract sense" happens to be one which is NOT true for the atalef of the Torah.
    And yet even so, Chazal used precisely that term, thereby leading everyone for the last 1500 years (except for The Great Rabbi Meiselman) to think that they were talking about the same creature.

    Y'know, according to me, Chazal's only deficiency was in not knowing zoology (which is no deficiency at all). You (and R. Meiselman), on the other hand, are positing that Chazal couldn't even talk straight and managed to be magnificently ineffectual at getting a simply point across.

    the term atalef happens to be the best way to describe it using Chazal's method of animal classification.

    Apologies, but this is ludicrous. For one thing, every Rishon understood Chazal to be referring to the Atalef of the Torah. Was their mesorah incorrect? What happened to the general principle that when all of the Rishonim agree on something, Acharonim can't overturn it?

    For another, even if your answer is "yes, all of the Rishonim were wrong, and R' Meiselman is the first in 1,500 years to correctly understand this gemara," you are making R' Slifkin's point.

    It is one thing to couch a difficult to accept concept in hidden language in order to ensure that only those wise enough to understand it can see the true meaning (as the Rambam explains in Chelek).

    But you are positing something else entirely: That Chazal deliberately chose misleading language to describe not the "Atalef" of the Torah, but some other creature, for no reason at all.

    As for "the best way to describe it", it would be a simple matter to say "but this Atalef is not the Atalef of the Torah" or "but this Atalef is not an Of".

    To argue that Chazal were describing a "different Atalef" - based purely on the conclusion that no winged creature fits the criteria - is both obviously circular and inherently rejects the very approach of R' Meiselman on other issues. After all, why not simply say that such a creature existed, but is now extinct? Or that it existed, but its nature changed? Or that it exists on the metaphysical level? Or that it still exists today, but hasn't been found?

    More, once used, the same "method" of "resolving" difficulties is open for use in any other area of learning. See an apparent contradiction in two gemaras? You can't learn out a diyuk - because the diyuk only applies if Chazal were speaking about the same thing in both mkoros. Given R' Meiselman's logic here, isn't the simpler answer to simply say that though Chazal were using the same word, they were using it to mean different things in the two different places?

    1) This is not halacha, so rules of P'sak (Rov Minyan U'Binyan) are not applicable.

    2) You are here contradicting R. Meiselman's thesis. He claims that no authorities disagree with him. That is why he classifies Rav Avraham Ben HaRambam and Rav Sherira Gaon as forgeries, then claims Rav Herzog was based completely the on "forgery" of R. Avraham (had he known, he would not have said it) and that Rav Sholomo Zalman wasn't serious when he wrote that it wasn't clear that anyone could argue on Rav Avraham (he also doesn't accurately translate Rav Shlomo Zalman). Rav Meiselman never claims to know better than Rav Herzog and Rav Shlomo Zalman.

    You don't seem to understand. It's not because Chazal chose to be obscure and decided to use a specific name in order to refer to a generic creature.
    It's because they didn't know the precise identity of the platypus, they had no choice but to use atalef in the generic sense.

    "And this "generic, abstract sense" happens to be one which is NOT true for the atalef of the Torah."

    Of course being a generic term as well as a specific one, atalef also accurately describes the bat, otherwise it wouldn't be used for both animals.
    And Rashi dos NOT define the atalef in the Torah as specifically the bat. Rashi says the bat in the Torah is the tinshemes. So the atalef is somewhat obscure even in the Torah.

    "And yet even so, Chazal used precisely that term, thereby leading everyone for the last 1500 years (except for The Great Rabbi Meiselman) to think that they were talking about the same creature."

    As I said, according to this approach, Chazal had no choice but to use this misleading term because they did not know the precise identity of the creature they were describing.

    And somehow you manage to praise Rabbi Josh Waxman for his idea of the strix as the atalef even though that suggestion also results in Chazal misleading everyone for the last 1500 years (until the Great Rabbi Waxman discovered their true meaning).

    Seems that as long as the suggestion maintains Chazal made a scientific error, it gets a free pass from you, but when a parallel suggestion says Chazal were not mistaken, it gets mocked and ridiculed.

    Of course being a generic term as well as a specific one, atalef also accurately describes the bat, otherwise it wouldn't be used for both animals.

    If you're defining the generic meaning as "creature with some characteristics of ohf and non-ohf", then what makes their statement not refer to the bat?

    somehow you manage to praise Rabbi Josh Waxman for his idea of the strix as the atalef even though that suggestion also results in Chazal misleading everyone for the last 1500 years

    Do you really not see the difference? According to Rabbi Waxman's proposal, Chazal understood that the strix was ALWAYS the EXCLUSIVE meaning of atalef. Whereas according to R.

  63. RNS,

    Your issue with Chazal misleading everyone assumes that people understood Atalef as a species, not a class. If names it would be understood as a class-name (which of course represents all its members correctly, by definition), then there was never any misleading going on.

    Obviously, there are lots of places where a descriptor will refer specifically to a species. When the statement is referring to a specific halacha which requires us to know the exact animal in question, that would necessarily be the case. For non-halachik matters…I don't see why, logically, it must be true. Do we have a reason to assume the descriptor is a species, not class?

    (Note-What are the specific characteristics of the atalef according to R' Meiselman? If the bat is the only flying creature with such attributes, then it could be a class in the Torah too--with the bat as it's only member. I would not be surprised, in fact if MANY of the species mentioned have "subspecies" [for example, "Lizard" and "Owl" have many "subspecies"] )

    Look, according to you, Chazal are on an entirely different plane of knowledge to the rest of mankind, such that they would never accept a scientific belief of their era unless they somehow knew that there was no possibility of it being wrong. And according to you, Chazal had a grasp of the underlying metaphysics of the world such that they knew that there must be an egg-laying mammal. And yet, despite all this superhuman knowledge, they didn't realize that everyone learning the Gemara after them, with the exception of R. Meiselman, would think that they are referring to the atalef of the Torah!

  65. Your issue with Chazal misleading everyone assumes that people understood Atalef as a species, not a class. If names it would be understood as a class-name (which of course represents all its members correctly, by definition), then there was never any misleading going on.

    Yes there is, because the only known member of that class (at that time) does not fit the description that Chazal give to it.

    ReplyDelete
  66. Further: If the term "atalef" is just a loose class that can include creatures as diverse as bats, platypuses and echidnas, and Chazal didn't know how many such diverse types there could be, then the whole Gemara becomes ridiculous: "Everything that bears live young, nurses them, and everything that lays eggs, gathers food for its young, except for all the creatures that this does not apply to."

    ReplyDelete
  67. I thought there was something in my proposal which indicated it, even explicitly. Namely the final paragraph:

    Furthermore, people often are bothered that the atalef is mentioned in the list of non-kosher birds in the Torah, yet it is not a bird. I don't regard this as a problem in the first place. עוף simply means "flying creature", and the Torah need not engage in scientific classifications. However, for those who are bothered by it, they should realize that they are being bothered by a particular translation of the word atalef. But, as I argued in this post, it seems rather likely that according to Chazal, the atalef was not a bat at all!

    Rabbi Slifkin and David Ohsie:

    You still do not get it.
    Chazal needed to use atalef--not because it is a class that covers every egg-laying mammal, but only because it is a type of egg-laying mammal that ALSO shares characteristics unique to bats.

    And since it was well known in the ancient world (via Aristotle and Pliny)that bats themselves do not lay eggs, they had no reason to think it would be confusing in the slightest to use the term atalef.

    (Going on about how Chazal should have known about the future confusion about atalef, or anything else, just like they knew about the existence a bat-like egg-laying mammal, is unfortunately reducing the maturity of the discussion to a kindergarten level.
    Just like you can just arbitrarily assert Chazal only were influenced by certain beliefs of Aristotle and Pliny but not by everything they believed, we can certainly have much more basis to say Chazal had limited expertise in Torah Sheba'al peh to derive knowledge of certain things about the world but not everything.)

    It was not "well known in the ancient world." It is not even well known today! That's why every subsequent student of the Talmud assumed it was talking about bats.

    Bottom line: If Chazal were talking about an animal that nobody knew the existence of, they should and would have said so, rather than using nothing more than the name of a known animal.

  70. Do Rishonim on the daf understand ataleif as bat, or is this all simply carrying over from the Torah's definitions?

    If they don't say "bat" on the daf, then it seems likely that they understood that it might not be the same thing, and the accusation of choosing misleading terms doesn't start (because it would indeed seem that Chazal correctly assumed that the future students would know that it isn't meant to be the same [because it's a class, or because they mean it in terms of certain characteristics, or whatever])

  71. Why not look at the daf instead of asking? Rashi in the daf writes in explanation of atalef,  קלב"א שורי"ץ דומה לעכבר ויש לו כנפים:

    That's why they called the Medieval period "the Dark Ages".

    Bottom Line: If Chazal wanted to find a name for a bat-like creature without knowing its specific name, and had reason to assume people knew bats do not lay eggs (either through observation or the science of their times), atalef is the most reasonable one to give.

  73. I find meisellmans Aristotelian objection sufficiently convincing to posit a theory of my own - taus sofer. Atalef clearly is a bat; bats clearly don't lay eggs and never have been thought to do so - some text relating to another egg laying creature must have been transposed. I don't believe that chazal made reckless random unsourced comments without adequate due diligence.

    The idea that it is a class such that it can refers to the platypus is a very big chiddush. This is the sort of novelty that, if it were so, one would certainly expect a Rishon to go out of his way to explain. Because his purpose is to act as a commentator, to explain what would otherwise be non-obvious. If the Rishon does not do so, the default should be that the Rishon understands the word כפשוטו, just like the other named creatures in context. The default should certainly NOT be that the Rishon assumes the rather surprising peshat.

    Hardly. My approach to the book is not like that Maniac's approach to my writings.

    You may be referring to R. Meiselman's statement that "the platypus is intermediary in appearance between mammals and birds in a number of ways. It is furry like a mammal, yet possesses a bill and webbed feet resembling those of a duck."

    The problem is that this does not help matters at all.

    You claimed that Chazal needed to use atalef--not because it is a class that covers every egg-laying mammal, but only because it is a type of egg-laying mammal that ALSO shares characteristics unique to bats. But a bill and webbed feet are NOT characteristics possess by bats!

    Alternately, you may be referring to R. Meiselman's alternate claimed defining characteristic of the atalef - that it can navigate in the dark, like the bat and mole. But here, too, there are problems. It is obviously completely contrived in order to obtain the desired result. There is no mention in the Gemara of this aspect nor any reason to suspect that it possesses the slightest significance. R. Meiselman is claiming that the factor is common to both bat and mole, basing himself on a Rashi that defines atalef as a mole. But that Rashi is simply a bizarre aberration, hardly sufficient to force a new category of atalef. It would be especially strange for R. Meiselman, since he so freely states that the Rishonim did not have a clear mesorah regarding the zoology of the Talmud.

    First of all, as noted, there was certainly not remotely adequate reason to assume that people knew bats do not lay eggs. People didn't even know that mice don't grow from dirt!

    Second, there would STILL be a much better way to say it:

    "Everything that bears live young, nurses them, and everything that lays eggs, gathers food for its young, except for the atalef, with which there is a type (yesh b'mino) that, even though it lays eggs, nurses its young."

    Of course, even this wouldn't answer the myriad of other problems, such as, How did they know that there was such a kind of creature, if they couldn't even derive from the Torah that the sun goes on the side of the world at night.

    But it's pointless for me to try to convince you. If you subscribe to R. Meiselman's approach, and to that of the Maniac Kornreich, then you believe that it is forbidden to believe that Chazal made a mistake here. Correct? You are convinced that any explanation, no matter how unreasonable, must be adopted, as a matter of principle. I addressed that manifesto in this post: http://www.rationalistjudaism.com/2013/12/a-recipe-for-intellectual-dishonesty.html

    So, rather than waste further time, please first indicate if you agree with R. Meiselman and Kornreich that it is forbidden to believe that Chazal erred here.

  79. The resolute will of a strong man..............struggles nobly with his foe to achieve great deeds.( Longfellow )
    Is having shown that the atalef is not a duck-billed platypus a great enough deed to justify so much effort spent on it.

    Yes, that was the defining characteristic Rav Meiselman was referring to--which excludes the echidna.
    There was no claim by Rav Meiselman that his suggestion was supported by the text of the gemara itself. But that doesn't mean it can be automatically ruled out and no independent analysis of the term used by that gemara is allowed to be brought to bear on that gemara.

    If every resolution of a difficult text requires local textual support, we would find a lot fewer solutions to problematic texts in rabbinic literature.


    "R. Meiselman is claiming that the factor is common to both bat and mole, basing himself on a Rashi that defines atalef as a mole. But that Rashi is simply a bizarre aberration, hardly sufficient to force a new category of atalef."

    Hardly an insurmountable obstacle. And Rav Meiselman is not "forcing". He is suggesting. If you don't like it, and you find too many difficulties with it, that's perfectly legitimate.
    But don't make the false claim that the platypus is just some random candidate pulled out of hat just because it's an egg-laying mammal.

    "First of all, as noted, there was certainly not remotely adequate reason to assume that people knew bats do not lay eggs. People didn't even know that mice don't grow from dirt!"

    Funny how you mention the dirt mouse. Maybe you should ask yourself how Rav Hirsch says people in Chazal's time came to think mice DID grow from dirt in the first place? The answer to that question--le'shitos'choh-- should provide an adequate reason to assume people in Chazal's time knew bats don't lay eggs.

    "Second, there would STILL be a much better way to say it:

    "Everything that bears live young, nurses them, and everything that lays eggs, gathers food for its young, except for the atalef, with which there is a type (yesh b'mino) that, even though it lays eggs, nurses its young."


    You are absolutely right. I must retract--Chazal could have been more clear. But that doesn't support your claim that using ataleif is misleading-- once you factor in the previous elements that go into this suggestion:
    1)Educated people in the Greco-Roman world would know from Aristotle and Pliny that bats do not lay eggs, and would assume Chazal in this context could only be referring to a bat-like creature.
    2) The platypus has enough significant bat-like characteristics to warrant being placed in its class under the common name ataleif.

    Look, as Rav Meiselman wrote in this very chapter, acceptance or rejection of this solution does indeed come down to what level of credit one gives Chazal at the outset.
    You obviously give Chazal none, and you are predisposed to think it is more reasonable to assume they must have been suddenly ignorant of conventional wisdom every time it happened to be scientifically correct.
    Therefore your absolute rejection in light of the slightest difficulty is entirely predictable. I really don't expect you accept it and I'm not trying to get you to. You are free to reject every single argument made to support every single position made in Rav Meiselman's book based on your definition of "reasonableness".

    I'm here to say one thing. Just don't falsely present these positions as if no supporting arguments were made for it whatsoever.

    It has "enough"? How many does it have?

    acceptance or rejection of this solution does indeed come down to what level of credit one gives Chazal at the outset.
    You obviously give Chazal none


    I give Chazal credit for being very wise and intelligent Talmud scholars, who made the same false assumptions made by millions of other intelligent people. You, on the other hand, feel that if they were wrong about a zoological fact, then it is somehow insulting, even though you don't think that this is the case with the Rishonim.

It doesn't smack of honesty to claim that means that Chazal wrote a definitive statement about atalef and didnt know what they were talking about when the talmud stamps it as definitive and correct.

  95. "Chazal" is not a person.
    In several places, in the Gemara and Midrash, there is mention of various members of Chazal who believed that the sun goes behind the sky at night.
    In one of these places, Pesachim, where it mentions that the chachmei Yisrael (i.e. the general Jewish view) believed that the sun goes behind the sky, it mentions ONE person, R. Yehudah HaNasi, who likewise formerly believed that, but subsequently changed his mind.

    ReplyDelete
  96. no, indeed no one frames the gemara that way. the gemara is framed that when the edited talmud was canonized the definitive position was rendered as being within the imprimatur of the promise Hashem made regarding the persistence of Oral Law. And the position of Rabbi Meiselman ( and the vast majority of all of the chchmei hamesorah) is that prior to that finalized canon the engagements of the chachamim were not branded as the imprimatur of the Torah she baal peh, and as we know, anyone can make a mistake, even the chachamim, yet once the stamp of the imprimatur is on something ( the canon that is finalized) the hashgocha of HKBH is that which all the sources R Meiselman brought and explained- persists ( among them pages 32, 33, 113, 120-132. The difference is delineated in the book. prior to canon, after canonized, definitive, not definitive, this is what you fail in your writings.

  97. Does Bava Basra 25a-b bear the "imprimatur" of God's seal of truth? Because there, Rabbi Eliezer and Rabbi Yehoshua speak about the sun going behind the sky. It makes no mention of their view being rejected.

    Of course, I disagree with yours and Rabbi Meiselman's claim that "the vast majority of all of the chchmei hamesorah" considered canonized claims in the Talmud to be indisputable. So, evidently, did Rav Hirsch, Rav Herzog, and so do many Gedolei Torah of our generation.

  98. R Slifkin and R Ohsie, R Slifkin wrote: "Presenting this [R Hirsch's] approach to the Gemara does not diminish the honor of Chazal." This is not clear at all to me.

    when i realized that rabbis based their rulings and interpretations on their science etc., it led me to assume that they also based their rulings on women etc. on the zeitgeist of their time (how can one draw the line, and where? for a random example, when Chazal read Vekasav Lah sefer krisus, in our day a Modern Orthodox Rabbi may have read the drasha to say a man MUST give a get, not that a Get MUST have been given willingly by the man, and one cannot force him).

    basically, by acccepting that the rabbis can be wrong on stuff and still be binding (and there is no higher daas torah crazy power that makes sure whatever they say is right) the majority of our torah is just a bunch of rabbis from long ago making their best guesses on things, including stuff that we now know to be wrong and/or immoral. One cant help but feel less honor for R Meir if he thinks that he was a bit spiteful towards women because of an inferiority complext with his wife. This is why the Chareidim hold fast to the alternative approach, of believing that what we see now is wrong and the ancients were always right.

    As my Rosh Yeshiva used to say, essentially the machlokes is where it is better to have the chiddush that addresses the issue.
    per R Hirsch, the science we see today is fine etc., but we must be mechadesh that irregardless of the Rabbis back then being totally wrong (and perhaps immoral based on the beleifs of their times), Divine Will still wants us to follow these rulings, even if they may be silly in today's eyes.
    The Chareidim just make a chiddush that everything they said is and will always be correct (and we are just wearing the wrong glasses today so we see things (e.g. science) incorrectly), so no chiddush needed with divine will or following the rabbinic rulings (which are per se all just and right, which we will realize one day).

    personally, both sides arent too satisfying. Do you disagree?

    (I'm not a Rabbi, please call me David. Also, my answer is obviously only for myself).

    1) The "Rationalist approach" is an approach. If it doesn't suit you, then it doesn't. Most of the argument here is that it is a legitimate approach, not that it is the only one.

    2) The alternative to infallibility is not agenda-driven decision making. So you seem to present a false choice.

    3) The Torah was given over to human beings to make decisions. This was simply not based on assumption of infallibility. If there was, then the Gemara could be thrown out because there would be no argument.

    4) R Hirsh did not say the rabbis were "totally wrong" or "immoral". See point #2. Fallible doesn't mean "totally wrong" or "immoral".

    So may answer to you is: All black and white models of the world will be unsatisfying, since the world is not black and white.

    So I disagree.

    ReplyDelete
  100. David, thank you for responding, and i agree with your general points and perspective.
    I did not mean to imply that R Hirsch held that everything Rabbis said was wrong (or immoral). my point was on specific halachic decisions where science is involved and the consensus (agreed to by R Slifkin) is that we still follow the halacha even though we now see that the basis is scientifically incorrect, it is a wild leap of faith to follow such laws. My addition of immoral is based on my assumption that while not every halachic decision is "agenda-driven", people are clearly affected by their times, and in my opinion that comes out most clearly with respect to halachos about other nations, as well as women's issues.

    When i read the Chinuch expplaining that girls are dirtier and lead to more disease as a basis for niddah/tumma'as leidah etc., i cant help but see it as a now-immoral understanding, and assume that many women's rules were also made based on such understanding, and perhaps against divine will).
    My problem is then what should i follow to be a good person and follow in God's ways, certain (of course not all) laws that are based on incorrect or immoral presumptions JUST BECAUSE stare decisis is easy, or try to reform and change all those laws now based on our understanding (i.e. become a Reformist). Do you not feel this struggle?

    Of course the world is not black and white, but how do you live with doing what is probably wrong scientifically) or immoral socially) from our perspective when really perhaps Divine Will is to do something else?

    Of course the chareidim are lucky, as their black/white approach protects them from ever having this issue.

  101. I recently saw a midrash that I think resolves this conflict.

    http://judaism.stackexchange.com/a/40109/4682

    The Tanhuma on Leviticus 1:7 says that the reason we bring sacrifices from animals and birds, but not from fish is because they are flesh and blood like us and their young are born from them, like us, whereas fish lay eggs from which babies are born.

    This is at first glance absurd. Obviously birds lay eggs, and obviously the Sages knew this, as there is an explicit verse about them in Deuteronomy 22:6. However, I think the resolution i quite simple when you consider that in general, birds fertilize eggs in the mother, by way of a cloacal kiss, meaning that the babies come out of the mother ready to be born.

    Female fish on the other hand generally lay their eggs, and then have them fertilized by the male, outside of the mother! In this way the midrash makes a lot of sense.

    In any event, we see that the Sages considered birds to have a commonality with animals, birthing their young from inside them. I do not think it is a terrible stretch to say that the Sages made another generalization, when it came to flying creatures, (generally being egg-layers), by including the bat.

  102. Greetings, Rabbi Dr. Natan Slifkin.

    I am not Jewish, nor do I claim to be familiar with the Hebrew Language in any manner. Nevertheless, the Torah is an important part of the foundation of my faith, and I believe that there is a simple and logical answer to this apparent enigma.

    The link to the image below is important.

    The image above demonstrates that the layout of the flyers in Leviticus 11 and Deuteronomy 14 is actually quite logical.

    First, notice that the bat is not placed arbitrarily among the list of the Chordate flyers, but it is always placed at the end (Lev 11:19B, Deu 14:18B).

    Also, there are two Phylum of flyers presented in those chapters. According to the Scientific Classification System, the Phylum must precede the class.

    In the King James Version, the Hebrew word (owph) that is rendered "fowl" is also rendered "flying" (Leviticus 11:21, 23) and "that flieth" (Deuteronomy 14:19). This justifies using "flyer" instead of "fowl" in Leviticus 11:13, and it is so rendered in the Concordant Literal Version (CLV):

    CLV "These you shall regard as abominable among the flyers..."

    But the ostrich, for example, is "winged" but can not "fly". The definition from the Strong's Concordance justifies rendering the word "winged".

    FACT: the FIRST group of flyers listed in Lev 11:13-19 are members of the CLASS Aves: birds.

    FACT: the LAST flyer listed in Lev 11:13-19 is a member of the CLASS Mamalia: the bat.

    FACT: birds are NOT members of the CLASS Mamalia.

    CONCLUSION: the bat is NOT a bird.

    CONCLUSION: the bat is NOT the eagle. 11:13.

    CONCLUSION: the bat is NOT the ossifrage. 11:13.

    CONCLUSION: the bat is NOT the ospray. 11:13.

    CONCLUSION: the bat is NOT the vulture. 11:14.

    CONCLUSION: the bat is NOT the kite. 11:14.

    CONCLUSION: the bat is NOT every raven. 11:15.

    CONCLUSION: the bat is NOT the owl. 11:16.

    CONCLUSION: the bat is NOT the night hawk. 11:16.

    CONCLUSION: the bat is NOT the cuckow. 11:16.

    CONCLUSION: the bat is NOT the hawk. 11:16.

    CONCLUSION: the bat is NOT the little owl. 11:17.

    CONCLUSION: the bat is NOT the cormorant. 11:17.

    CONCLUSION: the bat is NOT the great owl. 11:17.

    CONCLUSION: the bat is NOT the swan. 11:18.

    CONCLUSION: the bat is NOT the pelican. 11:18.

    CONCLUSION: the bat is NOT the gier eagle. 11:18

    CONCLUSION: the bat is NOT the stork. 11:19.

    CONCLUSION: the bat is NOT the heron. 11:19.

    CONCLUSION: the bat is NOT the lapwing. 11:19.

    INQUIRY: IF Leviticus is Taxonomically unreliable, THEN from the text of Leviticus 11:13-19, and the Scientific Classification System, LOGICALLY CONCLUDE that the bat is a bird...

    Thus, the apparent enigma becomes a point of accuracy.
