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.

Albert SchweitzerCivilization 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.
