To be ethical is to endeavor to find one's proper place in the larger scheme of things rather than to seek to assert human superiority over the natural world.
Gary SteinerNot only are animals unable to avail themselves of language to assert their own rights, but many fewer humans have a clear sense of kinship with animals than have a clear sense of kinship with other humans. Among beings with subjective states of awareness, animals are the untouchable caste, those whom human others would rather not acknowledge, let alone render assistance.
Gary Steiner
