Quote by Karl Popper (1902-1994)

• Philosophers should consider the fact that the greatest happiness principle can easily be made an excuse for a benevolent dictatorship. We should replace it by a more modest and more realistic principle - the principle that the fight against avoidable misery should be a recognized aim of public policy, while the increase of happiness should be left, in the main, to private initiative.

• We hate the very idea that our own ideas may be mistaken, so we cling dogmatically to our conjectures.

• All life is problem solving.
