A quotation from Russell, Bertrand

I think nobody should be certain of anything. If you’re certain, you’re certainly wrong, because nothing deserves certainty, and so one ought always to hold all one’s beliefs with a certain element of doubt and one ought to be able to act vigorously in spite of the doubt.

Bertrand Russell (1872-1970) English mathematician and philosopher
Interview by Woodrow Wyatt, BBC TV (1959)
