Humane Quotes (page 64)
Just as we reject racism, sexism, ageism, and heterosexism, we reject speciesism. The species of a sentient being is no more reason to deny the protection of this basic right than race, sex, age, or sexual orientation is a reason to deny membership in the human moral community to other humans.
Gary L. Francione
Individual psychotherapy - that is, engaging a distressed fellow human in a disciplined conversation and human relationship - requires that the therapist have the proper temperament and philosophy of life for such work. By that I mean that the therapist must be patient, modest, and a perceptive listener, rather than a talker and advice-giver.
Thomas Szasz
