Interpretations of Probability
At “Casting Lots” I tried to use the relationship between the field of statistics and Divine Providence as a means of looking at the verse “Hipil pur hu hagoral — he cast a pur,...

Casting Lots
Regardless of what one believes about Creation and the origin of the species, we have evolution since then. In order to even entertain the possibility of evolution as the origin of the species, one...
Midgets on the Shoulders of Giants
Someone recently (when I first wrote an earlier version of this post, Feb 2007) asked me about nisqatnu hadoros, the decline over time from one generation to the next. How is this possible, given...
A Physics Metaphor for Coming to Terms with Theodicy
As I’ve mentioned in the past, Aristotle believed that motion was caused by an intellect imparting impetus to an object, which then moved until the impetus ran out. Newton replaced this model of physics...
He Should Inspect His Deeds
אמר רבא ואיתימא רב חסדא: אם רואה אדם שיסורין באין עליו, יפשפש במעשיו. שנא’ (איכה ג): נַחְפְּשָׂה דְרָכֵינוּ וְנַחְקֹרָה, וְנָשׁוּבָה עַד ה’. פשפש ולא מצא, יתלה בבטול תורה. שנאמר (תהילים צד): אשְׁרֵי הַגֶּבֶר אֲשֶׁר...
Any Torah Which Has No Ancestral Home
Certain mitzvos must be done on a specific day, such as the beris milah of a boy who is healthy on the 8th day, or the Qorban Pesach. In these cases, the mitzvah overrides...
Aristotle, Science and Halakhah
ר’ יצחק בי רבי אלעזר שאל זרק מרשות היחיד לרשות הרבים ונזכר עד שהוא ברשות הרבים. על דעתיה דר’ עקיבה יעשה כמי שנחה בר”ה ויהא חייב שתים. א”ר חונה לא חייב ר’ עקיבה אלא...
Not for the Seder Table
We say in the Hagadah אמר רבי אלעזר בן עזריה: הרי אני כבן שבעים שנה ולא זכיתי שתאמר יציאת מצרים בלילות, עד שדרשה בן זומא “למען תזכור את יום צאתך מארץ מצרים כל ימי...
Hagadah: Random Thought
וַיְהִי בַיָּמִים הָרַבִּים הָהֵם וַיָּמָת מֶלֶךְ מִצְרַיִם, וַיֵּאָנְחוּ בְנֵי-יִשְׂרָאֵל מִן הָעֲבֹדָה, וַיִּזְעָקוּ; וַתַּעַל שַׁוְעָתָם אֶל הָאֱ-לֹהִים, מִן הָעֲבֹדָה. It was in those many days and the king of Egypt died, and the Benei Yisrael...
39 Melakhos
(Expanded from a couple of months ago.) שֵׁשֶׁת יָמִים, תֵּעָשֶׂה מְלָאכָה, וּבַיּוֹם הַשְּׁבִיעִי יִהְיֶה לָכֶם קֹדֶשׁ, שַׁבַּת שַׁבָּתוֹן לַה’; כָּל-הָעֹשֶׂה בוֹ מְלָאכָה, יוּמָת. Six days work shall be done, and the seventh day shall...
Halakhah and Phenomenology – Symbolic Logic
This will only be of interest to people who care about Symbolic Logic and about the rules of birur, of resolution of doubt in halachic questions. But I found something I wrote back in...
A Quantum of Time
There are two halachic indivisible units of time. When it comes to interruption, or for defining a single statement (e.g. when correcting oneself in davening) the unit is tokh kedei dibbur — within the...

Glory and Egalitarianism
I want to share, with permission, the following exchange I had with Ellen Rosen, a member of The Mussar Institute. On Thu, Dec 30, 2010 at 09:15:00AM -0800, Erosen1@aol.com wrote: I have a question...
Halakhah and Phenomenology – Addendum: Placebos
One more thought about my “Halakhah and Phenomenology” series…. A basic assumption behind the series is that what justifies looking at the world as experienced and as it could be directly experienced is the...
Halakhah and Phenomenology – The Unknown and Bitul
The Yerushami (Challah 3:5) discusses the case of when bread which didn’t have challah taken (or flour which didn’t have terumah taken from it), fell into a quantity of already separated bread. The gemara...
Pesaq Without Resolution
In “Invoking Tradition” I suggested that the amora’im of the Yerushalmi would not add their own interpretations to the words of the tana’im. The traditions must be preserved in their integrity. (And in “On...
When Science and Torah Conflict
(Initial post: With thanks to R’ Eli Turkel for providing some of the sources and all of the motivation for this post. (Dec 21st: Significantly expanded to include sources I dug up for further...
Explaining Tragedy
It seems to me, the overall question of theodicy and explaining why tragedy enters the lives of anyone but the most evil, can be addressed on two levels. Philosophically, the question is unanswerable. As...
Tevel is Called Holy
The Mishnah in Maaser Sheini 5:4 discusses the obligation to be finished with all maaser by the Pesach after the third and sixth years of the shemittah cycle. The mishnah describes messages sent to...
On Nets and Pieces
The story so far: In the first post, I suggested that it was Rav Yehudah, founder of the Yeshiva in Pumbedisa, who really developed the style of shaqla vetarya (dialectic) that we find in...
Invoking Tradition
So, I recently described Rav Yehudah’s trip down to Pumbedisa, where he founded a yeshiva where learning was based on the dialectic method, the style of shaqla vetarya (question and answer) that typifies the...
Clouds of Glory
I There is a famous dispute between Rabbi Eliezer and Rabbi Aqiva about what it is we commemorate with the mitzvah of sukkah. The Torah reads (Vayiqra 23:42-43): בַּסֻּכֹּ֥ת תֵּֽשְׁב֖וּ שִׁבְעַ֣ת יָמִ֑ים כָּל־הָֽאֶזְרָח֙ בְּיִשְׂרָאֵ֔ל...
M-Theory and Creation
There is much todo in some circles about Stephen Hawking’s latest book, “The Grand Design”. Co-written by Leonard Mlodinow, but it’s Hawking’s name in science and sheer genius that gives the book its gravitas,...
Terumah and Maaser
It is interesting to contrast the Chinukh’s description of terumah, the first gift taken from one’s produce, given to a kohein, with his description of ma’aser rishon, the tenth given to the levi’im. Terumah,...

Because they did not serve…
In response to my previous post, Shmuel commented: “They learned facts from their rabbeim, but without spending the time that comes from watching them live, they didn’t learn attitude.” That statement alone is worth...
Reality vs. Potential
