The soul is an Idea in the thinking thing, arising from the reality of a thing existing in Nature. Its duration and change therefore depend upon the duration and change of the thing to which it belongs. The soul may be united either with the body of which it is the Idea or with God, without whom it can neither exist nor be known. If the soul is united only with the body, it perishes when the body perishes, since the body is the foundation of its love. But if it is united with something unchangeable and lasting, it too must remain unchangeable and lasting. It cannot destroy or alter itself, just as it could not bring itself into existence. Only that which causes its existence can also cause its non-existence, by changing or perishing itself.

If only we consider attentively what the Soul is, and whence its change and duration originate, then we shall easily see whether it is mortal or immortal.
Now we have said that the Soul is an Idea which is in the thinking thing, arising from the reality of a thing which exists in Nature. Whence it follows that according to the duration and change of the thing, so must also be the duration and change of the Soul. We remarked, at the same time, that the Soul can become united either with the body of which it is the Idea, or with God, without whom it can neither be, nor be known.
On the Immortality of the Soul is listed on Textopian as an essay by Baruch Spinoza, dated 1660 CE.
