Famous quotes containing the words constructive, set and/or theory:

    “Work is a responsibility most adults assume, a burden at times, a complication, but also a challenge that, like children, requires enormous energy and that holds the potential for qualitative, as well as quantitative, rewards. Isn’t this the only constructive perspective for women who have no choice but to work? And isn’t it a more healthy attitude for women writhing with guilt because they choose to compound the challenges of motherhood with work they enjoy?”
    —Melinda M. Marshall (20th century)

    “Prudence suspects that happiness is a bait set by risk.”
    —Mason Cooley (b. 1927)

    “Freud was a hero. He descended to the “Underworld” and met there stark terrors. He carried with him his theory as a Medusa’s head which turned these terrors to stone.”
    —R.D. (Ronald David)
