No sadder proof can be given by a man of his own littleness than disbelief in great men.
Thomas Carlyle

Is anything sadder than a train
That leaves when it’s supposed to,
That has only one voice,
Only one route?
There’s nothing sadder.Primo Levi
We are no longer the same, you wiser but not sadder, and I sadder but not wiser, for wiser I could hardly become without grave personal inconvenience, whereas sorrow is a thing you can keep adding to all your life long, is it not, like a stamp or an egg collection, without feeling very much the worse for it, is it not.
Samuel Beckett
I shall, without further discussion of the other theories, attempt to contribute something towards the understanding and appreciation of the Utilitarian or Happiness theory, and towards such proof as it is susceptible of. It is evident that this cannot be proof in the ordinary and popular meaning of the term. Questions of ultimate ends are not amenable to direct proof. Whatever can be proved to be good, must be so by being shown to be a means to something admitted to be good without proof.
John Stuart Mill
By my physical constitution I am but an ordinary man ... Yet some great events, some cutting expressions, some mean hypocracies, have at times thrown this assemblage of sloth, sleep, and littleness into rage like a lion.
John Adams
I am obliged to interpolate some remarks on a very difficult subject: proof and its importance in mathematics. All physicists, and a good many quite respectable mathematicians, are contemptuous about proof. I have heard Professor Eddington, for example, maintain that proof, as pure mathematicians understand it, is really quite uninteresting and unimportant, and that no one who is really certain that he has found something good should waste his time looking for proof.
