Thought for the Day: When It Is Permitted to Nullify a Forbidden Substance

I once had a boss who loved to poke fun at any religion.  He stopped trying with me after a few attempts, though, for a couple of reasons.  The first was because every time he tried to point out a logical inconsistency with my belief system, I was always able to show him the issue was his lack of knowledge and not my beliefs.  The turning point was when he thought we could not even a molecule of pork; he was very disappointed when I explained the concept of bitul to him.  The second was that he was an avid bird watcher and would sometimes show me pictures of some of the more exotic birds he had seen.  One had two, single, long feather straight back from its tail.  "Isn't that amazing?", he exclaimed.  "Yes!", I rejoined, "What's the evolutionary advantage it gets from extra weight and drag on his body that will make flight more difficult and therefore make him an easier target for predators?"  He didn't like me very much.

Usually, bitul is a b'di'avad affair.  We have a rule (Shulchan Aruch Y.D. 99:5) of "ein m'vatlin issur l'chatchila"/one is not permitted to nullify a forbidden substance.  That is, one is not permitted to add issur even though it's taste will not be noticeable (even to an expert).  For example, some preservatives and settling agents are not kosher; a company seeking kosher certification would need to find kosher alternatives.  Moreover, one is likewise not allowed to add heter to a mixture into which issur fell in order to nullify it.  For example, if one ounce of milk fell into 30 ounces of beef stew, one would not be allowed to add another 30 ounces of stew to nullify it.  (I chose beef stew and not chicken soup because the M'chaber permits one to nullify an issur d'rabanan.  It's and interesting question if an Ashkenazi Jew is permitted to ask his S'fardi friend to fix up his chicken soup.)

There is, however, one case where one is, in fact, permitted to nullify issur: when the process that nullifies the issur is not being done to nullify it.  Huh?  The classic example is honey.  Raw honey i always teeming with bee parts.  Not whole bees, just parts; apparently the honey collection process is brutal enough to dismember any bee that tries to go down with her hive.  Apparently, honey is not uniformly sweet, so honey needs to be cooked.  That is, the cooking is done as part of the normal processing of the honey.  A side benefit of cooking the honey is that the bee parts dissolve and one is left with much less that one part in 60 -- Ta Da!  bees are nullified and honey is kosher.

This can come up at home, also.  Frozen raspberries have bugs (not might have bugs, they have bugs).  If you grind up the raspberries in a blender, you would smash those bugs to smithereens; again nullifying them.  You are not allowed to blend the raspberries just to smash up the bugs; so this won't get you raspberry soup.  However, a fruit smoothy is made by blending the fruit (and, presumably, other ingredients) to a delectable much; hence the term "smoothy".  In that case, you can even make your smoothy with raspberries.

You don't want to question having smashed up bug bits in your food... trust me, just look away.  Unless you are really interested, then look here, in the FDA's Defect Levels Handbook.  There you can find legal levels of all sorts of unappetizing things in your food.  I told you not to look.

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…
