Immortal «part» of the soul in Aristotle’s teaching, in Spinoza’s Ethics, and in peripatetic Maimonides’ reception of the rabbinic doctrine of man’s “Share in the world-to-come”

The author compares the ideas of Aristotle and Spinoza on the «immortality»/«eternity» of the wise one’s “mind”/“soul”, not excluding the Stagirite’s immediate influence on Spinoza in this aspect. The paper also deals with the possible influence of the rabbinic doctrine of one’s “share in the World-to-Come” in its Maimonides’ interpretation on Spinoza’s teaching concerning the eternal “part” of the wise one’s soul.
