Famous quotes containing the words generally, composed, straight, line and/or segments:
“Peer pressure is not a monolithic force that presses adolescents into the same mold. . . . Adolescents generally choose friend whose values, attitudes, tastes, and families are similar to their own. In short, good kids rarely go bad because of their friends.”
—Laurence Steinberg (20th century)
“In a universe that is all gradations of matter, from gross to fine to finer, so that we end up with everything we are composed of in a lattice, a grid, a mesh, a mist, where particles or movements so small we cannot observe them are held in a strict and accurate web, that is nevertheless nonexistent to the eyes we use for ordinary livingin this system of fine and finer, where then is the substance of a thought?”
—Doris Lessing (b. 1919)
“Mathematics ... would certainly have not come into existence if one had known from the beginning that there was in nature no exactly straight line, no actual circle, no absolute magnitude.”
—Friedrich Nietzsche (18441900)
“Our first line of defense in raising children with values is modeling good behavior ourselves. This is critical. How will our kids learn tolerance for others if our hearts are filled with hate? Learn compassion if we are indifferent? Perceive academics as important if soccer practice is a higher priority than homework?”
—Fred G. Gosman (20th century)
“It is not, truly speaking, the labour that is divided; but the men: divided into mere segments of menbroken into small fragments and crumbs of life, so that all the little piece of intelligence that is left in a man is not enough to make a pin, or a nail, but exhausts itself in making the point of a pin or the head of a nail.”
—John Ruskin (18191900)
