Famous quotes containing the words form and/or factor:
“Our ability to fall in love requires enough comfort with our masculinity to join it with someone’s femininity and feel enhanced. . . . If our mother made us feel secure and proud in our masculinity, then we want to find that again in our wife. If we are really comfortable with our mother, we can even marry a woman who is a friend rather than an adversary, and form a true partnership.”
—Frank Pittman (20th century)
“Weapons are an important factor in war, but not the decisive factor; it is people, not things, that are decisive. The contest of strength is not only a contest of military and economic power, but also a contest of human power and morale. Military and economic power is necessarily wielded by people.”
—Mao Zedong (1893–1976)
