Famous quotes containing the words national, centers and/or prediction:
“Perhaps our national ambition to standardize ourselves has behind it the notion that democracy means standardization. But standardization is the surest way to destroy the initiative, to benumb the creative impulse above all else essential to the vitality and growth of democratic ideals.”
—Ida M. Tarbell (1857–1944)
“[Madness] is the jail we could all end up in. And we know it. And watch our step. For a lifetime. We behave. A fantastic and entire system of social control, by the threat of example as effective over the general population as detention centers in dictatorships, the image of the madhouse floats through every mind for the course of its lifetime.”
—Kate Millett (b. 1934)
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
