The highest proof of the spirit is love. Love the eternal thing which can already on earth possess as it really is.

To the truly ethical man, all of life is sacred, including forms of life that from the human point of view may seem lower than ours.

We are united with all life that is in nature. Man can no longer live his life for himself alone.

We need a boundless ethic, one which will include the animals, too. Until we extend the circle of his compassions to all living things, we will not find peace.

The spirit of the age is filled with the disdain for thinking.

You ask me for a motto. Here it is: SERVICE.

Knowing all truth is less than doing a little bit of good.
