Thought for the Day: How Chazal View Evolution

Ok... get over it; I was also surprised to discover that Chazal addressed evolution. Who would have thunk? Where? Here (Brachos 61b): R' Akiva explained why he was teaching Torah in public -- even though the government had outlawed such assemblies on pain of death -- with a parable: A fox saw  fish darting together from one place to another. He asked them from what were they fleeing. They responded from the nets that people were bringing to catch them. The fox suggested that they join him to live together with him on dry land as his ancestors and their ancestors had done. (Italics mine, but that's how R' Akiva phrased the fox's proposal.) The fish said to the fox: Everyone extols you for being the most insightful (פיקח) of the animals. You are not insightful; you are a fool (טיפש)! If we are afraid in an environment that supports our life, how much more so would be afraid in an environment that does not supply even the basic necessities for us to live!

So... I first wondered why they called the fox a fool; I thought he we being sneaky and trying to con them into being his meal plan. Apparently the fish (and, by extension, R' Akiva) didn't see it that way. But the 500 lb gorilla here: "live together with him on dry land as his ancestors and their ancestors had done"?! Umm... what? When did foxes and fish live together? The Marharsha gives a beautiful and insightful explanation of the נמשל of R' Akiva's משל; but nary a word on the משל itself. Neither did ArtScroll quote nor note any sources. I finally found an explanation from the אמרי בינה brought in a footnote in the M'sivta Shas.

Of course I'll tell you what he said and what I think it means; but, first... my signature non-sequitur scenario whose relevance only becomes clear in the end. (At least, that is my plan, hope, and belief.)

Scientists love/live to build models. The models are built from and are meant to explain measurements in the physical world. (That's really a science, in a nutshell.) As an example of the kind of activity would be to build a model of water density as a function of temperature. (As models become more mature, they cover more phenomena and dependencies. But it's always just more of the same.) So our scientist would begin by building a lab in which he could both set and measure with extreme precision the volume and temperature of water samples. He would acquire ultra pure water to be sure he could reproduce his results. He would take 100s or 1000s of measurements.

Let us further imagine that our scientist can only make measurements between 40° and 200° Fahrenheit. He will build a model based on his measurements. Also based on his measurements, he will be able to tell you the accuracy with which he is reporting his results. You ask him, "What is the density of pure water at 45°?" He will report a number with confidence bounds. Of course, if you ask him for a density outside the range which he has measured, he will tell you that the results will be less accurate -- with the decrease in accuracy increasing as you get further outside the range in which he has measured; but he will be able to tell you precisely how much error you can expect. He is a very good scientist who follows all the correct protocols and knows his topic very, very well.

Now you ask him for the density of water at 211° and at 213°. He will confidently give you two numbers, the number at 213° being larger that at 211° by just a little bit, with a concomitantly larger uncertainty. His number for 211° will be right on target. His number for 213°, though, will be wrong; laughably and ridiculously wrong. Not because of bad measurements. Not because he is a bad scientist. It will be wrong because he didn't know that liquid water becomes a gas (aka steam) at 212°. He didn't know because it is outside his range of experience. He is quite adept at the scientific method, and everyone agrees; his ability to take careful data and construct reasonable models is not in question. What is in question is whether he is insightful or a fool. If he responds, "Hmm... fascinating. I must explore the implications of this new data."; then he is insightful. If, however, he responds, "My data and methods are unimpeachable. Reality has a problem." -- then he is a fool. But who could possibly be so ridiculously foolish?

Says the אמרי בינה, the fox is saying that since the world was originally all covered in water, obviously his ancestors and the fishes' ancestors had lived together. But the fox is a fool; because their ancestors had not even been created yet.

So that's the problem. Evolution is not in and of itself foolish. If you never heard about the order of creation, or about the idea of creation, then you have to come up with something. All those careful measurements, all that thought. But when you find out that you were missing a key piece of information, then you have two choices: (1) To ignore reality because it doesn't fit with your idea of what should be. (2) Accept reality, work out the implications of that crucial bit of new information, and then change your world view accordingly.

Who could possibly be so ridiculously foolish as to ignore the reality of מתן תורה and just continue on as if his world hadn't been just turned upside down? Who, indeed.

Thought for the Day: Pizza, Uncrustables, and Stuff -- What Bracha?

Many years ago (in fact, more than two decades ago), I called R' Fuerst from my desk at work as I sat down to lunch.  I had a piece of (quite delicious) homemade pizza for lunch.  I nearly always eat at my desk as I am working (or writing TftD...), so my lunch at work cannot in any way be considered as sitting down to a formal meal; aka קביעת סעודה.  That being the case, I wasn't sure whether to wash, say ha'motzi, and bentch; or was the pizza downgraded to a m'zonos.  He told if it was a snack, then it's m'zonos; if a meal the ha'motzi.  Which what I have always done since then.  I recently found out how/why that works. The Shulchan Aruch, 168:17 discusses פשטיד''א, which is describes as a baked dough with meat or fish or cheese.  In other words: pizza.  Note: while the dough doesn't not need to be baked together with the meat/fish/cheese, it is  required that they dough was baked with the intention of making this concoction. ...

Thought for the Day: What Category of Muktzeh are Our Candles?

As discussed in a recent TftD , a p'sak halacha quite surprising to many, that one may -- even לכתחילה -- decorate a birthday cake with (unlit, obviously) birthday candles on Shabbos. That p'sak is predicated on another p'sak halacha; namely, that our candles are muktzeh because they are a כלי שמלאכתו לאיסור and not  מוקצה מחמת גופו/intrinsically set aside from any use on Shabbos. They point there was that using the candle as a decoration qualifies as a need that allows one to utilize a כלי שמלאכתו לאיסור. Today we will discuss the issue of concluding that our candles are , in fact, a כלי שמלאכתו לאיסור and not מוקצה מחמת גופו. Along the way we'll also (again) how important it is to have personal relationship with your rav/posek, the importance of precision in vocabulary, and how to interpret the Mishna Brura.  Buckle up. After reviewing siman 308 and the Mishna Brura there, I concluded that it should be permissible to use birthday candles to decorate a cake on Sha...

Thought for the Day: Why Halacha Has "b'di'avad"

There was this Jew who knew every "b'di'avad" (aka, "Biddy Eved", the old spinster librarian) in the book.  When ever he was called on something, his reply was invariably, "biddy eved, it's fine".  When he finally left this world and was welcomed to Olam Haba, he was shown to a little, damp closet with a bare 40W bulb hanging from the ceiling.  He couldn't believe his eyes and said in astonishment, "This is Olam Haba!?!"  "Yes, Reb Biddy Eved,  for you this is Olam Haba." b'di'avad gets used like that; f you don't feel like doing something the best way, do it the next (or less) best way.  But Chazal tell us that "kol ha'omer HaShem vatran, m'vater al chayav" -- anyone who thinks HaShem gives partial credit is fooling himself to death (free translation.  Ok, really, really free translation; but its still true).  HaShem created us and this entire reality for one and only one purpose: for use...
