Picnic Quotes (1 quote)
The demand for certainty is one which is natural to man, but is nevertheless an intellectual vice. If you take your children for a picnic on a doubtful day, they will demand a dogmatic answer as to whether it will be fine or wet, and be disappointed in you when you cannot be sure.
From 'Philosophy For Laymen', collected in Unpopular Essays (1950, 1996), 38. This idea may be summarized as “What men want is not knowledge, but certainty” — a widely circulated aphorism attributed to Russell, but for which Webmaster has so far found no citation. (Perhaps it is a summary, never expressed in those exact words, but if you know the primary source, please contact Webmaster.)

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
