Thought for the Day: Everything We Learn from the Torah is Meant for Practical Application

Among the last few TftDs there has been discussions of how HaShem runs the world, i.e, השגחה/Divine Providence. I wondered if that was really a good term for what me mean, so I checked Google, and it's not bad:
Divine Providence, in theological terms, refers to G-d's intervention and guidance in the universe. It's the belief that G-d is actively involved in sustaining and directing creation, including human affairs, towards a specific purpose. This can be understood as both a general, ongoing governance of the universe and specific, extraordinary interventions in the lives of individuals.

In  any case, as a consequence, I have a new chavrusa! We are learning a two volume set on Faith, Divine Providence, and Free Will of שפתי חיים. (אמונה/Faith runs through both volumes, but the first volume focuses on Divine Providence, while the second on Free Will; within a Torah framework.) These volumes are based on the monthly talks given by R' Chaim Friedlander, z"tzl over many decades. The sefer includes a paraphrase of the introduction with which R' Chaim would begin these lectures. In short, he says that these topics are obviously at the core of the philosophical outlook of the Torah. These matters are intellectually deep, broad ranging, and encompass every dimension of Torah philosophy and מוסר/discipline. However, they also touch and are relevant to הלכה למעשה/practical observance of normative, day-to-day halacha.

As if that were not enough, the שפתי חיים adds: [these matters are relevant to הלכה למעשה] as do all the words of Chazal, the Rishonim, and the Acharonim. We were startled and read that again. How are all these matters relevant to practical halacha? Every gemara? There are some wild gemaras.

First, though, my second favorite topic, physics! By the mid-1800s, the laws of electricity and magnetism had been studied and elegantly summarized in four laws, known by the names of the main scientists in their development: Gauss, Coulomb, Faraday, and Ampère. A mathematician was bothered by a certain detail. They just didn't look balanced. So he added a term, known as the displacement current, that didn't change much as far as practical science, engineering, technology of the day. But it made the laws so beautiful and symmetrical. It did, though, mean that the electricity and magnetism could produce waves; theoretically speaking, of course. Some years later, another scientist, Hertz, actually made some waves in the laboratory. Then more people started looking. That led to radio, television, radar, X-rays, cell phones. You can argue how good that is; you can't argue how practical that is. So 100 years (give or take) after a mathematician fixed the beauty of some theoretical physics equations, we have oodles and oodles of practical applications.

Think about this: 100s and 1000s of students over decades learned about those equations. If you had asked any one of them why they needed to know that; of what practical use was that information? None of them would have known. Maxwell himself could not have imagined the impact his work would have on future generations.

So when you learn a gemara like Avoda Zara 34b that discusses the value of excrement from an animal that has gored and killed a human being versus that from an animal that has been dedicated to avoda zara... who knows why that information is vital? But it is Torah, therefore an integral part of the structure of reality.

Thought for the Day: Pizza, Uncrustables, and Stuff -- What Bracha?

Many years ago (in fact, more than two decades ago), I called R' Fuerst from my desk at work as I sat down to lunch.  I had a piece of (quite delicious) homemade pizza for lunch.  I nearly always eat at my desk as I am working (or writing TftD...), so my lunch at work cannot in any way be considered as sitting down to a formal meal; aka קביעת סעודה.  That being the case, I wasn't sure whether to wash, say ha'motzi, and bentch; or was the pizza downgraded to a m'zonos.  He told if it was a snack, then it's m'zonos; if a meal the ha'motzi.  Which what I have always done since then.  I recently found out how/why that works. The Shulchan Aruch, 168:17 discusses פשטיד''א, which is describes as a baked dough with meat or fish or cheese.  In other words: pizza.  Note: while the dough doesn't not need to be baked together with the meat/fish/cheese, it is  required that they dough was baked with the intention of making this concoction. ...

Thought for the Day: What Category of Muktzeh are Our Candles?

As discussed in a recent TftD , a p'sak halacha quite surprising to many, that one may -- even לכתחילה -- decorate a birthday cake with (unlit, obviously) birthday candles on Shabbos. That p'sak is predicated on another p'sak halacha; namely, that our candles are muktzeh because they are a כלי שמלאכתו לאיסור and not  מוקצה מחמת גופו/intrinsically set aside from any use on Shabbos. They point there was that using the candle as a decoration qualifies as a need that allows one to utilize a כלי שמלאכתו לאיסור. Today we will discuss the issue of concluding that our candles are , in fact, a כלי שמלאכתו לאיסור and not מוקצה מחמת גופו. Along the way we'll also (again) how important it is to have personal relationship with your rav/posek, the importance of precision in vocabulary, and how to interpret the Mishna Brura.  Buckle up. After reviewing siman 308 and the Mishna Brura there, I concluded that it should be permissible to use birthday candles to decorate a cake on Sha...

Thought for the Day: Why Halacha Has "b'di'avad"

There was this Jew who knew every "b'di'avad" (aka, "Biddy Eved", the old spinster librarian) in the book.  When ever he was called on something, his reply was invariably, "biddy eved, it's fine".  When he finally left this world and was welcomed to Olam Haba, he was shown to a little, damp closet with a bare 40W bulb hanging from the ceiling.  He couldn't believe his eyes and said in astonishment, "This is Olam Haba!?!"  "Yes, Reb Biddy Eved,  for you this is Olam Haba." b'di'avad gets used like that; f you don't feel like doing something the best way, do it the next (or less) best way.  But Chazal tell us that "kol ha'omer HaShem vatran, m'vater al chayav" -- anyone who thinks HaShem gives partial credit is fooling himself to death (free translation.  Ok, really, really free translation; but its still true).  HaShem created us and this entire reality for one and only one purpose: for use...
