I still think sincere pessimism the unpardonable sin.

There are two kinds of paradoxes. They are not so much the good and the bad, nor even the true and the false. Rather they are the fruitful and the barren; the paradoxes which produce life and the paradoxes that merely announce death. Nearly all modern paradoxes merely announce death.

It is generally the man who is not ready to argue, who is ready to sneer.

Every heresy has been an effort to narrow the Church.

An enormous amount of modern ingenuity is expended on finding defences for the indefensible conduct of the powerful. As I have said above, these defences generally exhibit themselves most emphatically in the form of appeals to physical science. And of all the forms in which science, or pseudo-science, has come to the rescue of the rich and stupid, there is none so singular as the singular invention of the theory of races.

Experience which was once claimed by the aged is now claimed exclusively by the young.
