My favourite aphorisms of the day, dreamt up in exam boards and the local Wetherspoons are:
'It is a total fallacy to think that knowledge helps you do something. Usually, if you are doing it right, it stops you doing it'.
'The pursuit of knowledge is a bit like the pursuit of alchemy. It's worth doing but there is a lot of crappy by-product'.
'We have knowledge because we have a word for it'.
