Life becomes harder for us when we live for others, but it also becomes richer and happier.
Albert SchweitzerIn 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 SchweitzerThe thinking (person) must oppose all cruel customs, no matter how deeply rooted in tradition and surrounded by a halo. When we have a choice, we must avoid bringing torment and injury into the life of another.
