Suppose the rationalists are right when they claim that we know some truths that no one ever taught us and that we could not have discovered by observing the world around us. Some rationalists explain those truths by saying they are innate; that is, we either are born with them in our minds or they develop naturally in our minds as we grow up. What are some ways that you think the presence of such truths in our minds could be explained, without relying on the rationalist theory of innate ideas?
