  Given innateness, Socrates ultimately arrives at a doctrine of pre-existence – that there is a stage of our existence, before this life, in which we came by our knowledge – and he goes on to use pre-existence in an argument for the immortality of the soul. This connection between innateness and immortality prompts Socrates’ deathbed discussion of innateness in the Phaedo, where the topic of discussion is the immateriality and immortality of the soul. Plato seems to be aware that the connection between Nativism and immortality is tenuous, but the purported tie will haunt (or edify, depending on one’s perspective) Nativism as it evolves in the modern period.
