In the Critique of Practical Reason, Kant grounds his postulate for the immortality of the soul on the presupposed practical necessity of the will’s endless progress toward complete conformity with the moral law. Given the important role that this postulate plays in Kant’s ethical and political philosophy, it is hard to understand why it has received relatively little attention. It is even more surprising considering the attention given to his other postulates of practical reason: the existence of God and freedom. The project of this paper is to examine Kant’s postulate of the immortality of the soul, examine critiques of this argument, and show why the argument succeeds in showing that belief in the moral law also obligates one to believe in the soul’s immortality.

The soul has played many different roles in philosophy and religion. Two of the primary functions of the soul are the bearer of personal identity and the foundation of immortality. In this paper I shall consider different interpretations of what the soul has been taken to be and argue that however we interpret the soul we cannot consistently maintain the soul is both what we are and what continues after our bodily death.

In the Dedicatory Letter of the Meditations, René Descartes claims that he will offer a proof of the soul’s immortality, to be accomplished by reason alone. This proof is also promised by the title page of the first edition of the Meditations, which includes the words “in which the existence of God and the immortality of the soul are demonstrated.” But in the Synopsis, and later in his replies to objections, Descartes gives a more nuanced account of the possibility of proving immortality and whether an attempt is even to be found in the Meditations. To confuse matters further, the title page of the second edition no longer mentions a demonstration of immortality but promises only to prove the distinction between body and soul. The question arises, therefore, whether the Meditations contains a purely philosophical demonstration of the immortality of the soul.

In this paper, I examine the thought of Descartes and Spinoza regarding the immortality of the soul. I conclude that Descartes’s argument(s) for the immortality of the soul—or at least the argument(s) that one can construct based on Descartes’s texts—are disappointing, and that Spinoza’s thought on the soul and its relation to the body leaves little room for the traditional doctrine of personal immortality.
