The aim of art, the aim of a life can only be to increase the sum of freedom and responsibility to be found in every man and in the world. It cannot, under any circumstances, be to reduce or suppress that freedom, even temporarily. No great work has ever been based on hatred and contempt. On the contrary, there is not a single true work of art that has not in the end added to the inner freedom of each person who has known and loved it.
The art of leading, in operations large or small, is the art of dealing with humanity, of working diligently on behalf of men, of being sympathetic with them, but equally, of insisting that they make a square facing toward their own problems.
The art of living does not consist in preserving and clinging to a particular mood of happiness, but in allowing happiness to change its form without being disappointed by the change for happiness, like a child, must be allowed to grow up.
