There's nothing situate under heaven's eye But hath his bond in earth, in sea, in sky. The beasts, the fishes, and the winged fowls Are their males' subjects and at their controls. Man, more divine, the master of all these, Lord of the wide world and wild wat'ry seas, Indu'd with intellectual sense and souls, Of more pre-eminence than fish and fowls, Are masters to their females, and their lords; Then let your will attend on their accords.
The best that Gauss has given us was likewise an exclusive production. If he had not created his geometry of surfaces, which served Riemann as a basis, it is scarcely conceivable that anyone else would have discovered it. I do not hesitate to confess that to a certain extent a similar pleasure may be found by absorbing ourselves in questions of pure geometry.
