Do you know when you may concede your insignificance? Before God or, perhaps, before the intellect, beauty, or nature, but not before people. Among people, one must be conscious of one's dignity.
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.
We are always more anxious to be distinguished for a talent which we do not possess, than to be praised for the fifteen which we do possess. Sometimes we are too close to the scene, to see clearly. We "know" ourselves so well that we cannot see how we are perceived by others. Our opinion of ourselves is only "one" opinion and it may not be the truth.
Consumption is the sole end and purpose of all production; and the interest of the producer ought to be attended to, only so far as it may be necessary for promoting that of the consumer.
