バートランド・ラッセルの名言・警句( Bertrand Russell Quotes )

Bertrand Russell Quotes 366

The scepticism that, I advocate amounts only to this:
(1) that when the experts are agreed, the opposite opinion cannot be held to be certain;
(2) that when they are not agreed, no opinion can be regarded as certain by a non-expert; and
(3) that when they all hold that no sufficient grounds for a positive opinion exist, the ordinary man would do well to suspend his judgment.
