Famous quotes containing the words open and/or class:
“All of the valuable qualities ... like helping in the development of others—will not get you to the top at General Motors, were that path open to women.... The characteristics most highly developed in women and perhaps most essential to human beings are the very characteristics that are specifically dysfunctional for success in the world as it is.... They may, however, be the important ones for making the world different.”
—Jean Baker Miller (20th century)
“It is the mark of an educated man to look for precision in each class of things just so far as the nature of the subject admits; it is evidently equally foolish to accept probable reasoning from a mathematician and to demand from a rhetorician demonstrative proofs.”
—Aristotle (384–323 B.C.)
