There are two excesses: to exclude reason, to admit nothing but reason. The supreme achievement of reason is to realise that there is a limit to reason. Reason's last step is the recognition that there are an infinite number of things which are beyond it. It is merely feeble if it does not go as far as to realise that.

Men despise religion. They hate it and are afraid it may be true.

Imagination decides everything.

Nothing fortifies scepticism more than that there are some who are not sceptics; if all were so, they would be wrong.

All the unhappiness of men arises from one single fact, that they cannot stay quietly in their own chamber.

Man's grandeur is that he knows himself to be miserable.

That a religion may be true, it must have knowledge of our nature.
