Bertrand Russell Ethics Quotations

We have in fact, two kinds of morality, side by side: one which we preach, but do not practice, and another which we practice, but seldom preach.

I can only say that, while my own opinions as to ethics do not satisfy me, other people's satisfy me still less.

Humanistic ethics is based on the principle that only humans themselves can determine the criterion for virtue and not an authority transcending us.

Science, by itself cannot, supply us with an ethic.
