Schopenhauer is well known for his assertion that what disappears with our demise is the most vulgar and uninteresting part of our existence: in other words, when we die our individuality goes away. That is not to say that everything that is us disappears with our final day of light. In the essay on “Immortality: a dialogue,” Schopenhauer puts it thus:
As far as you are an individual, death will be the end of you. But your individuality is not your true and inmost being: it is only the outward manifestation of it. It is not the thing-in-itself, but only the phenomenon presented in the form of time; and therefore with a beginning and an end. But your real being knows neither time, nor beginning, nor end, nor yet the limits of any given individual. It is everywhere present in every individual; and no individual can exist apart from it. So when death comes, on the one hand you are annihilated as an individual; on the other, you are and remain everything. (p.405 in T. Bailey Saunder’s translation)
What is less trumpeted is that Schopenhauer should have drawn some of his ideas from his colleague Spinoza, who wrote some 200 years earlier. Spinoza held that there really is only one substance — God — and everything else is part of this single substance. As Bertrand Russell noted in his History of Western Philosophy, Spinoza made this claim in distinction to Descartes, who had made a clear separation between mind — which is the element that allows us to connect with God — and matter, our physical, machine-like substance. What sets us apart from the determinism of matter was to Descartes our ability to perceive ideas, or, in his famous dictum, our ability to think: I think therefore I am.
Russell notes in no uncertain terms that Spinoza would take exception from this view: God is not only omnipotent, but is in fact everything. Thought and extension are attributes of this single substance, and, subsequently,
Individual souls and separate pieces of matter are, for Spinoza, adjectival; they are not things, but merely aspects of the divine Being. There can be no such personal immortality as Christians believe in, but only that impersonal sort that consists in becoming more and more one with God. (p. 571)
What is crucial is to perceive the way in which Spinoza arrived at a conclusion remarkably similar to Schopenhauer’s well-known rejection of individual immortality some centuries later: individuality is nothing but an aspect of our “true and inmost being,” and this being is timeless.
It follows that, for Spinoza, logical necessity is not limited to the material domain (as noted in this blog post): “Everything that happens is a manifestation of God’s inscrutable nature, and it is logically impossible that events should be other than they are” (ibid.).
Our path to contentedness? To find peace in the wisdom of knowing that things are the way they are by necessity, and that they could not be otherwise.
