Never say there is nothing beautiful in the world anymore. There is always something to make you wonder in the shape of a tree, the trembling of a leaf.

Civilization can only revive when there shall come into being in a number of individuals a new tone of mind independent of the one prevalent among the crowd and in opposition to it. A new public opinion must be created privately and unobtrusively. The existing one is maintained by the press, by propaganda, by organization, and by financial influences which are at its disposal. The unnatural way of spreading ideas must be opposed by the natural one, which goes from man to man and relies solely on the truth of the thoughts and the hearer's receptiveness of new truth.

Any profound view of the world is mysticism. It has, of course, to deal with life and the world, both of which are nonrational entities.

Every start on an untrodden path is a venture which only in unusual circumstances looks sensible and likely to succeed.

The deeper we look into nature, the more we recognize that it is full of life, and the more profoundly we know that all life is a secret and that we are united with all life that is in nature.

We ought all to make an effort to act on our first thoughts and let our unspoken gratitude find expression. Then there will be more sunshine in the world, and more power to work for what is good.

The doctor of the future will be oneself.
