Mathematics has beauties of its own - a symmetry and proportion in its results, a lack of superfluity, an exact adaptation of means to ends, which is exceedingly remarkable and to be found only in the works of the greatest beauty. When this subject is properly . . . presented, the mental emotion should be that of enjoyment of beauty, not that of repulsion from the ugly and the unpleasant.
