In the past we have tried to make a distinction between animals which we acknowledge have some value and other which, having none, can be liquidated when we wish. This standard must be abandoned. Everything that lives has value simply as a living thing, as one of the manifestations of the mystery that is life.
Albert SchweitzerNot one of us knows what effect his life produces, and what he gives to others; that is hidden from us and must remain so, though we are often allowed to see some little fraction of it, so that we may not lose courage.
Albert SchweitzerThe greatest living person in the world is some individual who at this very moment has gone in love to help another.
