To conquer fear is the beginning of wisdom.

You must believe that you can help bring about a better world. A good society is produced only by good individuals, just as truly as a majority in a presidential election is produced by the votes of single electors.

The use of self control is like the use of brakes on train. It is useful when you find yourself in wrong direction but merely harmful when the direction is right

What else is there to make life tolerable? We stand on the shore of an ocean, crying to the night and to emptiness. Sometimes a voice of one drowning, and in a moment the silence returns. The world seems to me quite dreadful, the unhappiness of many people is very great, and I often wonder how they all endure it. It is usually the central thing around which their lives are built, and I suppose if they did not live most of their lives in the things of the moment, they would not be able to go on.

I do not believe that I am now dreaming, but I cannot prove that I am not.
