Just as the largest library, badly arranged, is not so useful as a very moderate one that is well arranged, so the greatest amount of knowledge, if not elaborated by our own thoughts, is worth much less than a far smaller volume that has been abundantly and repeatedly thought over.
Arthur Schopenhauer, E. F. J. Payne (1974). “Parerga and Paralipomena: Short Philosophical Essays”, p.491, Oxford University Press
