Famous quotes containing the word act:
“We call the intention good which is right in itself, but the action is good, not because it contains within it some good, but because it issues from a good intention. The same act may be done by the same man at different times. According to the diversity of his intention, however, this act may be at one time good, at another bad.”
—Peter Abelard (10791142)
“Psychology has nothing to say about what women are really like, what they need and what they want, essentially because psychology does not know.... this failure is not limited to women; rather, the kind of psychology that has addressed itself to how people act and who they are has failed to understand in the first place why people act the way they do, and certainly failed to understand what might make them act differently.”
—Naomi Weisstein, U.S. psychologist, feminist, and author. Psychology Constructs the Female (1969)
“But the whim we have of happiness is somewhat thus. By certain valuations, and averages, of our own striking, we come upon some sort of average terrestrial lot; this we fancy belongs to us by nature, and of indefeasible rights. It is simple payment of our wages, of our deserts; requires neither thanks nor complaint.... Foolish soul! What act of legislature was there that thou shouldst be happy? A little while ago thou hadst no right to be at all.”
—Thomas Carlyle (17951881)
