Innatism

Innatism is an idea that some things we know come from our brains when we are born. It means that some of the things we know or understand are already in our brains, even before we learn them or experience them. For example, we already know how to talk, as humans, and even though kids still have to learn how to say words, the idea of talking and the ability to do so are already in our heads when we are born.
