Thought for the Day: Distinguishing Two Voices and Bitul

I always hate when a sefer has emblazoned all across the front, sides, and back: Do not take anything in this sefer as halacha l'ma'aiseh.  We are just kidding.  (Ok.. they don't usually add that last bit; but it's certainly implied.. or at lest inferred... at least by me.)  I would never do such a thing.  On the other hand, I am in no danger whatsoever of being taken seriously.  I guess that might make a difference...

Talking about hearing aids, there is an issue that has nothing to do with Shabbos or Yom Tov; namely, being yotzi one's obligation via the "shomei'a k'onah" (hearing is like saying) channel.  Minchas Shlomo, after a fair amount of pilpul and analysis, comes to the conclusion that hearing the sound generated by a hearing aid -- no matter how much it mimics and parallels the incoming sound -- just isn't the same sound that was generated from the source.  Bottom line, and as much as he appreciates the hardship and difficulties for someone who is hearing impaired, he cannot be yotzi with "shomei'a k'onah".  Minchas Shlomo is not the only opinion out there, but....

Suppose, however, one were to remove the device from one ear.  That way he would be hearing the direct voice as well as the electromechanically amplified voice.  Does that help or make things worse?  I might make things worse because there is a general principle of "trei kali lo mishtami" (two voices cannot be distinguished).  Hence, one is no better off; even a person who is not hard of hearing would not be yotzi (kiddush, for examle) in that situation.  However, for shofar and k'ri'as megilla, since those mitzvos are so beloved, we do say that two voices can be distinguished and one can choose to pay attention to the voice that will motzi him.  One small problem... the whole reason he is wearing hearing aids is that he can't hear very well.  Won't that render the whole issue moot since the direct voice will be overwhelmed by the amplified voice?

Not comes my chiddush.  In bitul, R' Yehuda has an interesting shita.  Whereas normally we say that a small quantity is negated by 60 times the volume (bitul b'shishim), that is, says R' Yehuda, is for min b'eino mino (two diferent flavors), but if the flavor of the two foods is identical (kosher and non-kosher wine, for example), then there is not bitul at all, not ever.  Moreover, the word used in the poskim to discuss the ability to tell the difference is "margish" (feel), not "to'em" (taste).  So... if you can apply the taste logic to hearing, then it comes out that R' Yehuda, who is usually the machmir, is meikel in this case and the half direct/half hearing aid advice would work out great.  In fact, it would even work for kiddush where we normally do say "trei kali lo mishtami".

You may not agree with this line of reasoning at all.  In fact, the people I have tried it out on so far were moved only so far as to say, "That's interesting" while slowly backing away.  Geniuses are never appreciated in their own time.  Neither are nuts, of course.

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: 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: 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…
