“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.”

“Not 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.”

“Human beings have capitalized on the silence of animals, just as certain human beings have historically imposed silence on certain other human beings by denying slaves the right to literacy, denying women the right to own property, and denying both the right to vote.”

“Our highest endeavor must be to develop free human beings who are able of themselves to impart purpose and direction to their lives. The need for imagination, a sense of truth, and a feeling of responsibility—these three forces are the very nerve of education.”

“The fantastically wasteful prodigality of human tongues, the Babel enigman, points to a vital multiplication of mortal liberties. Each language speaks the world in its own ways. Each edifies worlds and counter-worlds in its own mode. The polyglot is a freer man.”

“If we do not believe within ourselves this deeply rooted feeling that there is something higher than ourselves, we shall never find the strength to evolve into something higher.”

“The capacity for imaginative reflex, for moral risk in any human being is not limitless; on the contrary, it can be rapidly absorbed by fictions, and thus the cry in the poem may come to sound louder, more urgent, more real than the cry in the street outside. The death in the novel may move us more potently than the death in the next room. Thus there may be a covert, betraying link between the cultivation of aesthetic response and the potential of personal inhumanity.”
