In a 1951 article in the New York Times Magazine, Bertrand Russell laid out “the Ten Commandments that, as a teacher, I should wish to promulgate”:
- Do not feel absolutely certain of anything.
- Do not think it worthwhile to produce belief by concealing evidence, for the evidence is sure to come to light.
- Never try to discourage thinking, for you are sure to succeed.
- When you meet with opposition, even if it should be from your husband or your children, endeavor to overcome it by argument and not by authority, for a victory dependent upon authority is unreal and illusory.
- Have no respect for the authority of others, for there are always contrary authorities to be found.
- Do not use power to suppress opinions you think pernicious, for if you do the opinions will suppress you.
- Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.
- Find more pleasure in intelligent dissent than in passive agreement, for, if you value intelligence as you should, the former implies a deeper agreement than the latter.
- Be scrupulously truthful, even when truth is inconvenient, for it is more inconvenient when you try to conceal it.
- Do not feel envious of the happiness of those who live in a fool’s paradise, for only a fool will think that it is happiness.
“The essence of the liberal outlook in the intellectual sphere is a belief that unbiased discussion is a useful thing and that men should be free to question anything if they can support their questioning by solid arguments,” he wrote. “The opposite view, which is maintained by those who cannot be called liberals, is that the truth is already known, and that to question it is necessarily subversive.”
