Thought for the Day: Clearing the Confusion about Doubt

I learned another new word this week: selvage.  To produce a woven garment, one must first attach several threads to a frame, forming a sort of harp like effect of parallel threads; that's called the warp.  One then weaves a thread or threads through the warp (above one and below the next); that's called the weft.  At the conclusion of that process, their are some threads from the warp and/or weft sticking out.  Those may be cut off or, as often happens, they may be woven either together or with other threads to form a margin around the garment.  That margin (finished with another weaving or not) is known as selvage.  (Selvage is better than usufruct, because (1) you might actually have an occasion to use it, and (2) it doesn't sound like you are saying something rude.)

What's important about that, you ask.  I am so glad you asked!  Tzitzis are to be placed "on the corner" of a garment.  The Torah is precise: on the corner garment, not on the edge of the garment (so must be an inch away from the edge); on the corner of the garment, not on the body of the garment (so must be within three inches of the edge).  The problem is that we do not have a clear mesorah for how to handle selvage vis a vis the tzitzis.  Do we consider the garment to end before or after the selvage?  The recommendation is to trim the edges of the garment at the corners; which is what you will all talisos ("taleisim", in Yiddish).

The situation regarding the selvage itself, however, remains in doubt.  Not because I don't know how garments are made, not because I don't know how exactly to attach tzitzis.  The safeik here is not that I have a lack of clarity; the safeik is that we have a clear and definite uncertainty about the status of the selvage.

The rule, "safeik d'oraisa l'chumra, safei d'rabanan l'kula" is a rule about how to conduct oneself when the situation if one of clear doubt.  It is not a rule about what do to when you don't know what's going on.  Not being sure what bracha to make on a food, for example, is certainly not a case of "safeik"; it's a case of ignorance.  Hence, you can't say, "Well, I am in doubt about what bracha to make, so I'll make the default sh'ha'kol."  The Mishna Brura says the rule for ignorance is: go learn, but until you know, don't eat.

What's a situation of safeik?  There's the selvage mentioned above.  Strawberries, bananas, and pineapple all have roots that live for years, but foliage that dies every year.  Similarly to the selvage situation, there is a clear safeik about whether that is considered a tree or not in halacha.  Another clear safeik occurs when I can't remember making a bracha on the apple I am eating.  None of those are cases of ignorance regarding the relevant halacha, rather the status of the situation itself is -- without a doubt -- in doubt.

There now; that should be clear.

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…
