"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 Schweitzer
"Ask not what an animal can do for you; ask what you can do for an animal." Jasper
"The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for white, or women created for men." ~Alice Walker
The source of the quote is Walker's preface to Marjorie Spiegel's 1988 book, "The Dreaded Comparison" . Her next sentence was, "This is the gist of Ms. Spiegel's cogent, humane and astute argument, and it is sound."
