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 SchweitzerWhen man learns to respect even the smallest being of creation...nobody has to teach him to love his fellow man. Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he who is cruel to animals cannot be a good man.
Albert SchweitzerNot less strong than the will to truth must be the will to sincerity. Only an age, which can show the courage of sincerity, can possess truth, which works as a spiritual force within it.
