If people would stop objectifying abstractions (which they probably never will), or if they would stop objectifying the abstractions they make consciously (which they might learn to do), at least half the pseudo-questions befuddling the world today - as they have befuddled it since time immemorial - would vanish. And that would be a very, very great gain.

 Cassius Jackson Keyser
Mathematics, even in its present and most abstract state, is not detached from life. It is just the ideal handling of the problems of life.
