How much should intolerance be tolerated?

And how should we decide what sort of intolerances are tolerable?

They’re just some of the questions that one of the leading philosophers of the 20th century, Sir Karl Popper turned his hugely influential mind to. 

The 2025 Sir Karl Popper Memorial Lecture is being given on Monday 2 June, and an Australian philosopher is presenting it. 

GUEST:

Peter Godfrey-Smith Professor of History and Philosophy of Science at the University of Sydney
