1. Human, humane may refer to that which is, or should be, characteristic of human beings. In thus describing characteristics, human may refer to good and bad traits of a person alike ( human kindness; human weakness ). When emphasis is placed upon the latter, human is thought of as contrasted to divine: To err is human, to forgive divine. He was only human. Humane (the original spelling of human, and since 1700 restricted in meaning) takes into account only the nobler or gentler aspects of people and is often contrasted to their more ignoble or brutish aspect. A humane person is benevolent in treating fellow humans or helpless animals; the word once had also connotations of courtesy and refinement (hence, the application of humane to those branches of learning intended to refine the mind).
