Bertrand Russell talking about exact thinking in philosophy

Transcript: "But I do like clarity and exact thinking, and I believe that very important to mankind. Because when you allow yourself to think inexactly, your prejudices, your bias, your self-interest, comes in in ways you don't notice, and you do bad things without knowing that you're doing them (self-deception is very easy). So that I do think clear thinking [is] immensely important. But I don't think philosophy in the old-fashioned sense is quite the thing the world needs nowadays. I think its needs are rather different."
