A system of logic for messianic phenomena
Silman, S. 2002.  BH 13:123-137. CELD ID 21434

Classically, natural phenomena are described by a 2-valued logic. In the writings of Hasidism and Kabbala we find that the phenomena of the messianic era are characterized by a paradoxical combined natural-and-miraculous world order. The use of 2-valued logic is inadequate to describe such phenomena. Thus, it is suggested that a 3-valued logic be used as a model for these messianic phenomena. First introduced in the 1920s, 3-valued logics are now in common use in some computer languages and have been suggested as models for the paradoxical phenomena of quantum mechanics. This paper is based on research done at the Rabbi Yisroel Aryeh Leib Research Institute on Moshiach and the Sciences, of which the author is director. It is dedicated to the memory of Rabbi Yisroel Aryeh Leib ben Rabbi Levi Yitzchok Schneerson, whose fiftieth yartseit was observed this year.
