Science arouses a soaring sense of wonder. But so does pseudoscience. Sparse and poor popularizations of science abandon ecological niches that pseudoscience promptly fills. If it were widely understood that claims to knowledge require adequate evidence before they can be accepted, there would be no room for pseudoscience.
If I have not been exposed and am not in any danger of pursuit. But I have been exposed, I am pursued - by myself! That is a pursuer that does not readily let go.
I never cheat or steal. Also, I never wear a top-hat with a sack coat or munch bananas in public on the streets, because a gentleman does not do those things either. I would as soon do the one as the other sort of thing--it is all a matter of harmony and good taste.
Perfection does not come from belief or faith. Talk does not count for anything. Parrots can do that. Perfection comes through the disinterested performance of action.
The pessimist is seldom an agitating individual. His creed breeds indifference to others, and he does not trouble himself to thrust his views upon the unconvinced.
