Bertrand Russell and uncertainty

"I think nobody should be certain of anything. If you’re certain, you’re certainly wrong because nothing deserves certainty. So one ought 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…. One has in practical life to act upon probabilities, and what I should look to philosophy to do is to encourage people to act with vigor without complete certainty." -Bertrand Russell
