Famous quotes containing the words physical and/or quantity:
“[In early adolescence] she becomes acutely aware of herself as a being perceived by others, judged by others, though she herself is the harshest judge, quick to list her physical flaws, quick to undervalue and under-rate herself not only in terms of physical appearance but across a wide range of talents, capacities and even social status, whereas boys of the same age will cite their abilities, their talents and their social status pretty accurately.”
—Terri Apter (20th century)
“Among the virtues and vices that make up the British character, we have one vice, at least, that Americans ought to view with sympathy. For they appear to be the only people who share it with us. I mean our worship of the antique. I do not refer to beauty or even historical association. I refer to age, to a quantity of years.”
—William Golding (b. 1911)
