Famous quotes containing the words power and/or technical:
“Quintilian [educational writer in Rome about A.D. 100] hoped that teachers would be sensitive to individual differences of temperament and ability. . . . Beating, he thought, was usually unnecessary. A teacher who had made the effort to understand his pupils individual needs and character could probably dispense with it: I will content myself with saying that children are helpless and easily victimized, and that therefore no one should be given unlimited power over them.”
—C. John Sommerville (20th century)
“The axioms of physics translate the laws of ethics. Thus, the whole is greater than its part; reaction is equal to action; the smallest weight may be made to lift the greatest, the difference of weight being compensated by time; and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (18031882)
