“I do like clarity and exact thinking. And I do think that’s very important to mankind. Because when you allow yourself to think inexactly your prejudices, your bias, your self-interests, comes in ways you don’t notice and you do bad things without knowing you do them. Self-deception is very easy. So that I do think clear thinking is immensely important.”
- Bertrand Russell
There is actually a clip of Russell speaking these words which can be seen here.
