Your soul suffers if you live superficially.

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

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.

A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help.

I always think that we live, spiritually, By what others have given us in the significant hours of our life. These significant hours do not announce themselves as coming, but arrive unexpected.

The the question whether I am a pessimist or an optimist, I answer that my knowledge is pessimistic, but my willing and hope are optimistic.

Even if it is a little thing, do something for those who have need of help.
