Thought for the Day: חלב ישראל and Camel Milk

Here's a fact that probably doesn't interest you at all:
Aside from cattle, many kinds of livestock provide milk used by humans for dairy products. These animals include buffalo, goat, sheep, camel, donkey, horse, reindeer, and yak. The first four respectively produced about 11%, 2%, 1.4% and 0.2% of all milk worldwide in 2011. (From Wikipedia... so you know it's true!)
Notice that most of those animals are kosher, so their milk is also kosher.  The only non-kosher animal that even made it into the top four is camel at 1.4%.

Why might that be an interesting factoid for you to file away?  The gemara wonders (Avoda Zara 35b) why Chazal instituted the decree of חלב ישראל.  After all, explains the gemara, milk from a kosher animal is white and can be made into cheese, whereas milk from a non-kosher animal is creamy/yellow and cannot be processed into cheese.  That being the case, we could easily detect if milk from non-kosher sources was added, so why do we need a special decree?  Now here's the deal... camel milk is white as snow (or at least as cow's milk) and you can actually make cheese from it.  Check it out.  Now what?

Before we talk about how to understand that this gemara in light of those facts, though, we need to ask a different question: Yeah!  Why did Chazal make a special decree for חלב ישראל?  If non-kosher ingredients were added, then of course it isn't kosher and if I don't have adequate supervision then of course I can't eat it!  After all, that is my answer to anyone who asks why I don't eat vegetarian or fish meals in non-kosher restaurants?

The answer to that question is that we don't really expect the goyim to add milk from non-kosher animals.  But it's one of those things that you don't really expect to have to worry about.  There is another food like that: דמאי (yes, Wikipedia has a Hebrew presence also).  These are cases where the Chazal saw a certain laxity in observance to which they wanted to encourage more care.

Given that, the gemara is not at all questioning what the purpose of the decree, the gemara is wondering where there is room for laxness.  After all, you can see the color and you can't make cheese out of it.  Regardless of the answer (see there), we still need to deal with the apparent contradiction of the gemara's statements to the reality we see with our own eyes.

The cheese issue is easiest.  The gemara is not telling you a הלכה למשה מסיני, it's telling you an observation.  In those days they didn't have the wherewithal to make cheese from camel.  Or can also say (as some rishonim do) that the gemara meant you can't make hard cheese; which is also true by observation.

The color issue is a bit trickier, but along the same lines.  The gemara is telling you an observation made in Babylonia that milk from kosher animals is white and from non-kosher animals is yellow/creamy.  In fact, the milk from a yak -- also a kosher animal and also not available in Babylonia -- is also yellow/creamy.  What about camels, though?  They certainly had camels and milk from a camel is certainly white.  To answer this requires some speculation, but its a very reasonable speculation (the kind where I am tempted to say, "so you have to say", but I never, ever say that).

Why would a goy add milk from a non-kosher animal into cow's milk?  Because he will otherwise have to throw it away.  Nobody drinks horse (mare) milk, nor cat milk, nor dog milk; so if the goy has a mare or a cat or a female dog (no, I am not going to say it), then he might throw that worthless milk into the mix.  However, he is most certainly not going to throw camel milk in there -- because he can sell camel milk!  And camel's milk is a lot more expensive than cow's milk.  If anything, he is more likely to put cow milk into the camel milk.

Thought for the Day: Using a Mitzvah Object for Non-Mitzvah Purposes

As I am -- Baruch HaShem -- getting older, I am more cognizant of the fact that I'd like to stay as healthy as possible right up the moment I leave this world.  Stuff hurting is not the problem (I am told there is an old Russian saying that once you are 40, if you wake up and nothing hurts -- you're dead), stuff not working, however, is a problem.  To that end, for several years now I commute to work by bicycle (weather permitting, 30 minutes on an elliptical machine when weather does not permit).  I recently took up some upper body weight training.  Not because I want to be governor of California, just simply to slow down loss of bone mass and extend my body's healthy span.  Simple hishtadlus.  I have an 18 month old grandson who is just the right weight for arm curls (yes... I am that weak), so I do about 10 reps when I greet him at night.  He laughs, I get my exercise; all good.  (Main problem is explaining to the older ones why zeidy can't give them the same "…

Thought for the Day: Thanking HaShem Each and Every Day for Solid Land Near Water

Each and every morning, a Jew is supposed to view himself as a new/renewed creation, ready for a new day of building his eternal self through Torah and mitzvos.  We begin the day with 16 brachos to praise/thank/acknowledge HaShem for giving us all the tools we need to succeed.  We have a body, soul, and intellect.  We have vision, mobility, and protection from the elements.  Among those brachos, we have one that perhaps seems a bit out of place: רוקע הארץ על המים/Who spreads out the land on/over the water.  After all, it's nice to have a dry place to walk, but does that compare to the gratitude I have for a working body and vision?  As it turns out, I should; as explained by the R' Rajchenbach, rosh kollel of Kollel Zichron Eliyahu (aka, Peterson Park Kollel).  Your best bet is to listen to the shiur; very distant second is to continue, which I hope will whet your appetite for the real thing.

First... since we have dry land, I don't have to slog to work through even a foot…

Thought for the Day: Hydroponically Grown Humans... I Feel Sick

I am quite openly not at all objective about abortion in particular and the treatment of human embryos and fetuses in general.  I am, after all, the survivor of a failed abortion attempt.  Not "thought about it, but couldn't go through with it"; not "made appointment, but then chickened out at the lost moment"; but, "tried a procedure, but was unsuccessful in attempt to abort".  Nonetheless, I try very hard to listen to the liberal arguments (which I also used to chant as part of the general liberal catechism), and am genuinely empathetic to the plight of women who find themselves in that difficult position.

What I heard on NPR this morning, however, has left me feeling physically ill.  You can read about it, if you like, but here's the bottom line:  Scientists in Cambridge have achieved a new record, they fertilized a human ova and then kept it alive in vitro (that is, in a test tube/petri dish in a laboratory) for 14 days.  The scientist involve…
