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)
“When Freedom, from her mountain height,
Unfurled her standard to the air,
She tore the azure robe of night,
And set the stars of glory there;”
—Joseph Rodman Drake (1795–1820)
“The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.”
—Thomas Henry Huxley (1825–95)
