“The belief that established science and scholarship—which have so relentlessly excluded women from their making—are “objective” and “value-free” and that feminist studies are “unscholarly,” “biased,” and “ideological” dies hard. Yet the fact is that all science, and all scholarship, and all art are ideological; there is no neutrality in culture!”

“The trouble with tea is that originally it was quite a good drink. So a group of the most eminent British scientists put their heads together, and made complicated biological experiments to find a way of spoiling it. To the eternal glory of British science their labour bore fruit.”
—George Mikes (b. 1912)
