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.

Anyone who has accustomed himself to regard the life of any living creature as worthless is in danger of arriving also at the idea of worthless human lives.

Man can no longer live his life for himself alone. We realize that all life is valuable and that we are united to all this life. From this knowledge comes our spiritual relationship to the universe.

Civilization can only revive when there shall come into being in a number of individuals a new tone of mind, independent of the prevalent one among the crowds, and in opposition to it - a tone of mind which will gradually win influence over the collective one, and in the end determine its character. Only an ethical movement can rescue us from barbarism, and the ethical comes into existence only in individuals.

Thought is the strongest thing we have.

I decided that I would make my life my argument.
