The mistake made by all previous systems of ethics has been the failure to recognize that life as such is the mysterious value with which they have to deal. All spiritual life meets us within natural life. Reverence for life, therefore, is applied to natural life and spiritual life alike. In the parable of Jesus, the shepherd saves not merely the soul of the lost sheep but the whole animal. The stronger the reverence for natural life, the stronger grows also that for spiritual life.

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.

From naive simplicity we arrive at more profound simplicity.

It is only through love that we can attain to communion with God. All living knowledge of God rests upon this foundation: that we experience him in our lives as Will-to-love.

Preservation of life is the only true joy.

The doctor of the future will be oneself.
