If it's worth doing, it's worth doing badly. (on not perfectionism to put things off) .

Pessimism is not in being tired of evil but in being tired of good. Despair does not lie in being weary of suffering, but in being weary of joy. It is when for some reason or other good things in a society no longer work that the society begins to decline; when its food does not feed, when its cures do not cure, when its blessings refuse to bless.

There is a great deal of difference between an eager man who wants to read a book and the tired man who wants a book to read.

The sceptics, like bees, give their one sting and die.

Right is Right even if nobody does it. Wrong is wrong even if everybody is wrong about it.

Latter-day scepticism is fond of calling itself progressive; but scepticism is really reactionary. Scepticism goes back; it attempts to unsettle what has already been settled. Instead of trying to break up new fields with its plough, it simply tries to break up the plough.

Science in the modern world has many uses; its chief use, however, is to provide long words to cover the errors of the rich.
