Full Idea
Our ability to picture how people are likely to respond may well be innate; indeed, our disposition to believe what other people tell us (which is fundamental to knowledge) could hardly be an inference, as that isn’t good enough for knowledge.
Gist of Idea
Knowledge depends on believing others, which must be innate, as inferences are not strong enough
