Abstract Classes

Famous quotes containing the words abstract and/or classes:

    If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning, concerning matter of fact and existence? No. Commit it then to flames: for it can contain nothing but sophistry and illusion.
    David Hume (1711–1776)

    The most powerful lessons about ethics and morality do not come from school discussions or classes in character building. They come from family life where people treat one another with respect, consideration, and love.
    Neil Kurshan (20th century)
