Bertrand Russell's "Ten Commandments"

I just discovered this, and I love it. This is Bertrand Russell's "Ten Commandments." 1: Do not feel absolutely certain of anything.

2: Do not think it worthwhile to produce belief by concealing evidence, for the evidence is sure to come to light.

3: Never try to discourage thinking, for you are sure to succeed.

4: 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.

5: Have no respect for the authority of others, for there are always contrary authorities to be found.

6: Do not use power to suppress opinions you think pernicious, for if you do the opinions will suppress you.

7: Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.

8: 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.

9: Be scrupulously truthful, even when truth is inconvenient, for it is more inconvenient when you try to conceal it.

10. 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.

I wonder what Russell would think of The Sum of Our Gods. On the one hand, it revels in uncertainty and shows very little respect for authority. On the other hand, while it strives to tell the truth, it's the truth of fictional characters. Would Russell consider fiction to be "scrupulously truthful" or merely convenient?
