About Baruch Spinoza

Baruch (Benedictus) Spinoza (1632–1677) was a Dutch philosopher of Portuguese-Jewish descent who developed a rigorous geometric metaphysics of God-or-Nature. Excommunicated from Amsterdam’s Jewish community in 1656, he ground lenses and wrote in Latin with a small circle of freethinkers.

Interpretation

Spinoza's claim is epistemological rather than about personal survival after death. In the Ethics he distinguishes the duration a body has from the eternity belonging to the mind's adequate ideas, which are not measured by time at all. To know something truly is, on his account, to participate in that. The sentence therefore reports a kind of experience available now, not a promise about later.

Why it matters

Read this way it is about a particular kind of knowledge: the understanding that sees things as necessary is not the sort of thing that ages.
