For many of us at the LSE in the 1950s, Professor Popper was the leading intellectual influence there. It was a privilege for second-year undergraduates to be taught by such a major figure. The biggest eye-opener was his insistence on the fallibility of knowledge, including his own.
In keeping with this arresting proposition, he would ask us to spend the second hour of each lecture period in criticising him. He would shout 'Criticise]' in a thick Germanic accent, and we would do our best to stand up to him. Needless to say, nobody ever got the better of him.
