 Bertrand Russell Quotes 366 |
Cocksure certainty is the source of much that is worst in our present world, and it is something of which the contemplation of history ought to cure us, not only or chiefly because there were wise men in the past, but because so much that was thought wisdom turned out to be folly- which suggests that much of our own supposed wisdom is no better.
