Eternal Life and the Body According to Spinoza
In this chapter, Matheron presents some brief thoughts on Proposition 39 of Part V of the Ethics, which states that a body capable of many things has a mind whose greater part is eternal. The key to unlocking this seemingly unusual claim is to understand what happens in the body when the mind understands. This leads Matheron to reconstruct the demonstrations that accompany the preceding propositions in Part V as well as to a discussion of adequate and inadequate ideas in Spinoza. Though we might not be immediately aware of it, to have an adequate idea of something external us is to have the adequate idea of a certain order that is established between affections in our body whose structure matches the one that inheres in the thing in question. This leads Matheron to a discussion of the ‘third kind of knowledge’ and its relation to the Spinozist concept of eternity, all of which clarify the initial starting point: the acquisition of new and more adequate knowledge always entails a clearer understanding of our body’s capacities that are already included in the eternal idea that we are.
