Equivalence Class Structure

Famous quotes containing the words class and/or structure:

“But the strong and healthy yeoman and husbands of the land, the self-sustaining class of inventive and industrious men, fear no competition or superiority. Come what will, their faculty cannot be spared.”
—Ralph Waldo Emerson (1803–1882)

“Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking faith, it nevertheless does not deride faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens. It tries to use reason to demolish a structure that is not built upon reason.”
—Sydney J. Harris (1917–1986)
