I tire (sounds a little too effectual), so I’ll start again. I get fed up with statements such as ‘people can’t learn from lectures’. it is obvious rubbish. Think AJP taylor. Think Jacob Bronowski. And then of course think of the mind-numbing lectures I seem to remember sitting through in second year medical school, one bloody virus after another. It all depends, doesn’t it? Lectures are not natural kinds: do drugs work?
