Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

“The lady—bearer of this—says she has two sons who want to work. Set them at it, if possible. Wanting to work is so rare a merit, that it should be encouraged.”
—Abraham Lincoln (1809–1865)

“The theory [before the twentieth century] ... was that all the jobs in the world belonged by right to men, and that only men were by nature entitled to wages. If a woman earned money, outside domestic service, it was because some misfortune had deprived her of masculine protection.”
—Rheta Childe Dorr (1866–1948)
