Putting the idea of innatism into question, John Locke (1632 – 1704) is a philosopher and a scientist, contributed much to the realms of philosophy, law and politics. He strongly believed in the innate goodness of humans and the right to freedom and property of the people. In this paper we will be looking at both Empiricism and Innate ideas and whether Locke’s ‘children and idiots’ argument against innate ideas is sound. Locke believes that people are born with blank slates, and that knowledge is acquired throughout one’s life through experiences and sensations. In the 18th century, Locke came up with the term empiricism. Empiricism is the view that most knowledge is derived from experience. Which means both senses and inner thought.
