The time you enjoy wasting is not wasted time.
Sir, why did you not give me better evidence?
I've made an odd discovery. Every time I talk to a savant I feel quite sure that happiness is no longer a possibility. Yet when I talk with my gardener, I'm convinced of the opposite.
Of all forms of caution, caution in love is perhaps the most fatal to true happiness.
My whole religion is this: do every duty, and expect no reward for it, either here or hereafter.
I hold all knowledge that is concerned with things that actually exist – all that is commonly called Science – to be of very slight value compared to the knowledge which, like philosophy and mathematics, is concerned with ideal and eternal objects, and is freed from this miserable world which God has made.
If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument. It is exactly of the same nature as the Hindu's view, that the world rested upon an elephant and the elephant rested upon a tortoise; and when they said, "How about the tortoise?" the Indian said, "Suppose we change the subject." The argument is really no better than that.
The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.
There is no nonsense so arrant that it cannot be made the creed of the vast majority by adequate governmental action.
The greatest challenge to any thinker is stating the problem in a way that will allow a solution.
