 Pomponazzi’s most complete discussion of the human soul was published in his 1516 On the Immortality of the Soul. The work builds on earlier discussions found in quaestiones delivered in 1503 and 1504 (Pomponazzi 2018; Poppi 1970: 27–92; Kristeller 1944) and in lectures on De anima given in 1514–15 (Bakker 2007). In On the Immortality of the Soul, he sought to establish whether the human intellect is separable and immortal using a methodology that did not exceed “natural limits”, that is, without supposing “something from faith or revelation” and to determine what is “in conformity with the words of Aristotle” (ch. 8). He cautioned that he did not affirm anything contrary to Thomas Aquinas’s views but his critiques advance “in the way of doubt and not of assertion” (ch. 8). Moreover, he tempered his considerations by declaring his preference for scripture over “human reasoning and experience” (ch. 8).
