IB Theory of Knowledge: An introduction by Professor AC Grayling

 

In this 10-minute clip, Professor AC Grayling introduces and evaluates the concept of knowledge as  ‘justified, true belief’. He discusses the conditions for making knowledge claims, and the objections of Edmund Gettier  to this definition of knowledge. He encourages reflection on the types of justification used to support knowledge claims in different areas of knowledge, including science and history.

This clip offers an excellent introduction for students new to TOK and for more experienced TOK students who want to think deeply about the distinctions between knowledge, truth, belief and justification.

On the same channel, there are further excellent clips on knowledge in history, natural science, ethics, the arts and mathematics.
