Thought for the Day: Moving Objects On Shabbos Comes In Two Flavors

The עירוב; much maligned, much abused.  Here are two of my favorite quotes (and my responses):
  • Oh yes, I know that R' SuchAndSuch, shlita/ztz"l doesn't believe in eiruvs [sic].
    • Response: Hmmm... Given that there is a masechta eiruvin, I am pretty darn sure that R' SuchAndSuch, shlita/ztz"l, does actually believe in עירובים just as much as he believes in kashrus.  Maybe it is his knowledge of the issue that is the source of his concerns?
  • I really don't know what the issues are with the eiruv, so I just use it.
    • Response: Hmmm... In case of doubt about a Torah prohibition, the rule is always to stringent.  Using ignorance as an excuse to risk spiritual excision seems as reckless as walking along the Grand Canyon with your eyes closed.
The problem is, of course, that people are all fired up that they are in broadcast mode before any discussion begins, so there is no dialog; only a lot of shouting.  My first Shavous in Dallas, the rabbi proposed that we discuss the Torah viewpoint on abortion.  Everyone agreed that would be interesting, and one fellow in particular was excited to show the rabbi the error of his ways.  When the rabbi walked in on Shavuous night, he said that we first needed to lay out the underlying issues.  Three or four hours later we had finally finished prerequisite materials.  What about Mr. ShowTheRabbiTheErrorOfHisWays?  After only an hour or so, it had become very clear to him  that his opinions were based on misconceptions and half-truths.  Faced with the shocking realization that he would need to alter his opinions if he took actual facts into account, he had left.

In that spirit, I would like to steadily develop a base of facts before actually formulating opinions about this or that עירוב.  Siman 346 develops the basic parameters in which all discussions of עירובים.  There are two distinct issues with carrying items on Shabbos that are problematic (read: forbidden) at the Torah level.

We need two definitions prior to stating the halacha: רשות היחיד/private domain and רשות הרבים/public domain.  Please note well that these terms have nothing to do with ownership.  A private domain -- at the Torah level -- is area enclosed by fences/walls, regardless of size.  There is a discussion about how this definition is affected by man-made vs naturally occurring (such as steep mountain sides and rivers/oceans) and also by the number of people crossing daily; but that's the basic idea.  A public domain is an open area that either has or could support (that's a BIG discussion) a daily throng of 600,000 people.

Issue #1 (in no particular order): Transporting an object between public and private domains.  The mode of transportation is irrelevent: carrying, throwing, or handing over; regardless of the direction, from public to private domain or from the private to public domain; in all cases the transportation is forbidden by the Torah.  Notice that there is no minimum or maximum distance; it is the crossing of the boundary itself that is forbidden.

Issue #2 (ditto on the order thing): Transporting an object more than four cubits (the ever popular ד' אמות -- irrelevant aside: Google translate got that exactly right!) in a public domain is forbidden by the Torah.  Interestingly, transporting an object up to (but not including) four cubits is completely permissible; both at the Torah and even Rabbinic levels.

Now... since these are Torah prohibitions, there is nothing that can be done to permit them.  That would be boring, so Chazal added their own prohibitions: (1) to and from and through a new domain (the כרמלית, a sort of pseudo public domain), and (2) crossing boundaries of any two domains (even one private to another).  Since Chazal forbad, Chazal can permit; enter (drum roll please...) the עירוב!  Now, as they say, the fun begins.

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…
