If mathematical truths were not so simple and obvious then the passions aroused in acknowledging them would lead to many difficulties. For if covetousness entered in then perhaps many housewives would determine that 2 x 2 = 5 and not 4. These things are only so obvious and simple that they can no longer be clouded by sympathy and antipathy. Continually wider regions will be grasped by this form of truth and more peace can come to mankind if truth is grasped in this manner.
