We cannot understand what happens in the universe. What is glorious in it is united with what is full of horror. What is full of meaning is united to what is senseless. The spirit of the universe is at once creative and destructive — it creates while it destroys and destroys while it creates, and therefore it remains to us a riddle. And we must inevitably resign ourselves to this.
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 Schweitzer
