# 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 is from your family, endeavour to overcome it with 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 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 will think that is happiness.
