“He who wishes to attain to human perfection, must therefore first study Logic…

 My son, so long as you are engaged in studying… Logic, you belong to those who go around the palace in search of the gates.”

(Moses Maimonides: Guide for the Perplexed.)

 I read [Judaic Logic] with great interest. It is a very important book, which has its place in every Jewish library.”

(Prof. Ely Merzbach, Bar Ilan University, editor of Higayon.)


Judaic Logic is divided into 15 chapters and 6 appendices, as well as some addenda and allied works.
