John locke (1632-1704) believed that knowledge is not innate. He believed that the mind is a tabula rasa (blank slate). For locke, all knowledge is derived from our experiences. Steven pinker (2002) has shown why the blank slate thesis is implausible. However, this does not mean that empiricism, the view that knowledge is derived from our senses, is implausible. Impossible for the mind to be completely blank. Rationalism: all (or majority) of our knowledge is derived from reason, most of our knowledge is innate think plato and descartes. Rationalists claim there are some moral principles that are innate in all humans. Empiricism: all (or majority) of our knowledge is derived from our senses, it is not innate think john locke and david hume. Moral nativists: believe morality is innate (a version of rationalism) Harm norms are a universal feature of morality.
