by Bertrand Russell.
- “Do not feel absolutely certain of anything. 
- Do not think it worthwhile to proceed by concealing evidence, for the evidence is sure to come to light. 
- Never try to discourage thinking, for you are sure to succeed. 
- Overcome arguments by arguments, not authority, for a victory dependent on 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 if the 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 would think that it is happiness. “
