It is agreed, in this country, that if a man can arrange his religion so that it perfectly satisfies his conscience, it is not incumbent on him to care whether the arrangement is satisfactory to anyone else or not

Man is the religious animal. He is the only religious animal. He is the only animal that has the True Religion –- several of them. He is the only animal that loves his neighbor as himself and cuts his throat, if his theology isn't straight. He has made a graveyard of the globe in trying his honest best to smooth his brother's path to happiness and heaven.

Man is the lowest animal.

If man had created man he would be ashamed of his performance

Adam was the only man who, when saying a good thing, knew that nobody had said it before him.

I have been studying the traits and dispositions of the "lower animals" (so called) and contrasting them with the traits and dispositions of man. I find the result humiliating to me.
