Famous quotes containing the words definition of, definition and/or terms:
“Scientific method is the way to truth, but it affords, even in
principle, no unique definition of truth. Any so-called pragmatic
definition of truth is doomed to failure equally.”
—Willard Van Orman Quine (b. 1908)
“Mothers often are too easily intimidated by their children’s negative reactions...When the child cries or is unhappy, the mother reads this as meaning that she is a failure. This is why it is so important for a mother to know...that the process of growing up involves by definition things that her child is not going to like. Her job is not to create a bed of roses, but to help him learn how to pick his way through the thorns.”
—Elaine Heffner (20th century)
“One of your biggest jobs as a parent of multiples is no bigger than simply talking to your children individually and requiring that they respond to you individually as well. The benefits of this kind of communication can be enormous, in terms of the relationship you develop with each child, in terms of their language development, and eventually in terms of their sense of individuality, too.”
—Pamela Patrick Novotny (20th century)
