No one can give a definition of the soul. But we know what it feels like. The soul is the sense of something higher than ourselves, something that stirs in us thoughts, hopes, and aspirations which go out to the world of goodness, truth and beauty. The soul is a burning desire to breathe in this world of light and never to lose it--to remain children of light.
Albert SchweitzerBut the others, those who tried to bring Jesus to life at the call of love, found it a cruel task to be honest. The critical study of the life of Jesus has been for theology a school of honesty. The world had never seen before, and will never see again, a struggle for truth so full of pain and renunciation as that of which the Lives of Jesus of the last hundred years contain the cryptic record.
Albert SchweitzerToday it is considered as exaggeration to proclaim constant respect for every form of life as being the serious demand of a rational ethic. But the time is coming when people will be amazed that the human race existed so long before it recognized that thoughtless injury to life is incompatible with real ethics. Ethics is in its unqualified form extended responsibility to everything that has life.
