Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

“it pleaseth me when I see through the meadows
The tents and pavilions set up, and great joy have I
When I see o’er the campana knights armed and horses arrayed.

And it pleaseth me when the scouts set in flight the folk with
their goods;
And it pleaseth me when I see coming together after them an host of
armed men.”
—Bertrans De Born (fl. 12th century)

“We commonly say that the rich man can speak the truth, can afford honesty, can afford independence of opinion and action;—and that is the theory of nobility. But it is the rich man in a true sense, that is to say, not the man of large income and large expenditure, but solely the man whose outlay is less than his income and is steadily kept so.”
—Ralph Waldo Emerson (1803–1882)
