“Perhaps the most amazing sensation passed on to us by prehistoric man is that of presentiment. It will always continue. We might consider it as an eternal proof of the irrationality of the universe. Original man must have wandered through a world full of uncanny signs. He must have trembled at each step.”

UN Press Release SG/360 (22 December 1953)
Context: Our work for peace must begin within the private world of each one of us. To build for man a world without fear, we must be without fear. To build a world of justice, we must be just. And how can we fight for liberty if we are not free in our own minds? How can we ask others to sacrifice if we are not ready to do so?... Only in true surrender to the interest of all can we reach that strength and independence, that unity of purpose, that equity of judgment which are necessary if we are to measure up to our duty to the future, as men of a generation to whom the chance was given to build in time a world of peace.

The Faith that Heals (1910)
Context: A man must have faith in himself to be of any use in the world. There may be very little on which to base it — no matter, but faith in one's powers, in one's mission is essential to success. Confidence once won, the rest follows naturally; and with strong faith in himself a man becomes a local center for its radiation. St. Francis, St. Theresa, Ignatius Loyola, Florence Nightingale, the originator of every cult or sect or profession has possessed this infective faith. And in the ordinary everyday work of the doctor confidence, assurance (in the proper sense of the word) is an asset without which it is very difficult to succeed.

1900s, A Square Deal (1903)
Context: It is not enough to be well-meaning and kindly, but weak; neither is it enough to be strong, unless morality and decency go hand in hand with strength. We must possess the qualities which make us do our duty in our homes and among our neighbors, and in addition we must possess the qualities which are indispensable to the make-up of every great and masterful nation -- the qualities of courage and hardihood, of individual initiative and yet of power to combine for a common end, and above all, the resolute determination to permit no man and no set of men to sunder us one from the other by lines of caste or creed or section. We must act upon the motto of all for each and each for all. There must be ever present in our minds the fundamental truth that in a republic such as ours the only safety is to stand neither for nor against any man because he is rich or because he is poor, because he is engaged in one occupation or another, because he works with his brains or because he works with his hands. We must treat each man on his worth and merits as a man. We must see that each is given a square deal, because he is entitled to no more and should receive no less.
