“By this standard any thought or act may safely be judged.”
Source: Something More, A Consideration of the Vast, Undeveloped Resources of Life (1920), p. 84-85
Context: It is significant that the Great Teacher does not draw up a code of laws or list or sins. Nowhere does Jesus say explicitly that human slavery is a sin, or that the employment of little children for fourteen hours a day in a factory is a sin. He deals in general principles concerning the great fundamentals of life. So clear is his teaching, however, that there can be no doubt as to what he thinks of human slavery or the oppression of little children. In the teaching of Jesus, life is relationship, dwelling on friendly and affectionate terms with God, with ourselves, and with our fellowmen. Anything which destroys this relationship is sin. By this standard any thought or act may safely be judged.

“What is it that distinguishes man from animals? It is not his upright posture.”
"Affluence and Ennui in Our Society" in For the Love of Life (1986) translated by Robert and Rita Kimber
Context: What is it that distinguishes man from animals? It is not his upright posture. That was present in the apes long before the brain began to develop. Nor is it the use of tools. It is something altogether new, a previously unknown quality: self-awareness. Animals, too, have awareness. They are aware of objects; they know this is one thing and that another. But when the human being as such was born he had a new and different consciousness, a consciousness of himself; he knew that he existed and that he was something different, something apart from nature, apart from other people, too. He experienced himself. He was aware that he thought and felt. As far as we know, there is nothing analogous to this anywhere in the animal kingdom. That is the specific quality that makes human beings human.
