Full Idea
To say a Notion is imprinted n the Mind, and yet at the same time to say, that the mind is ignorant of it, and never yet took notice of it, is to make this Impression nothing.
Gist of Idea
Innate ideas are nothing, if they are in the mind but we are unaware of them

A Reaction
Not much of an argument, given that Locke would accept that we remember things, but have enormous difficulty recalling them. The introspective evidence of innateness I take to be the obviousness of a new idea, when it strikes.
