Russell's Ten Commandments of free Thoughts

Russell's Ten Commandments of free thoughts:
1. Do not be absolutely certain about everything;
2. Do not try to conceal the evidence because the evidence will eventually be exposed;
3. Don't be afraid of thinking, because thinking can always make people benefit;
4. When someone disagree with you, you should use arguments to persuade them, instead of using authority to conquer them, because the victory achieved by authority is illusory and self-deception;
5. Do not blindly worship any authority, because you can always find the opposite authority;
6. Do not use power to suppress opinions that you think are harmful, because if you suppress them, it only means that you have been squashed by these opinions;
7. Do not be afraid of holding your own unique views, because the common sense we accept has always been a unique view;
8. Instead of passively agreeing to others' opinions, it is better to express your opposition in a rational manner, because if you believe in your own wisdom, your objection indicates more consent;
9. Even if the truth is not pleasant, you must be honest, because it often takes more effort to conceal the truth;
10. Do not envy those who enjoy happiness in the heaven of the fools, because only the fools think that is happiness.
