Famous quotes containing the words science and/or career:
“In our science and philosophy, even, there is commonly no true and absolute account of things. The spirit of sect and bigotry has planted its hoof amid the stars. You have only to discuss the problem, whether the stars are inhabited or not, in order to discover it.”
—Henry David Thoreau (1817–1862)
“They want to play at being mothers. So let them. Expressing tenderness in their own way will not prevent girls from enjoying a successful career in the future; indeed, the ability to nurture is as valuable a skill in the workplace as the ability to lead.”
—Anne Roiphe (20th century)
