Famous quotes containing the word generations:
“The principle goal of education in the schools should be creating men and women who are capable of doing new things, not simply repeating what other generations have done; men and women who are creative, inventive and discoverers, who can be critical and verify, and not accept, everything they are offered.”
—Jean Piaget (18961980)
“Flowers so strictly belong to youth, that we adult men soon come to feel, that their beautiful generations concern not us: we have had our day; now let the children have theirs. The flowers jilt us, and we are old bachelors with our ridiculous tenderness.”
—Ralph Waldo Emerson (18031882)
“Ive finally figured out why soap operas are, and logically should be, so popular with generations of housebound women. They are the only place in our culture where grown-up men take seriously all the things that grown-up women have to deal with all day long.”
—Gloria Steinem (b. 1934)
