Descartes claims that God is a substance and that mind and body are two different and separable substances. This paper provides some background that renders these claims intelligible.

We can accept Plato's "ingredient principle" when we replace the distinction between things and properties with a slightly different one.

In Principia Philosophiae I 9, Descartes defines “thought” as follows: “By the name ‘thought’ I understand all that which happens in us such that we are conscious of it, insofar as there is consciousness of it in us”. I inquire how to read the "insofar as" in this definition.

Something is a document insofar as its official function is to compensate for the impossibility of immediately acquiring information that has a function (= plays a role in a practice).
