I have reflected; and I think I see the place of the amateur.

The obscure things, the details and disputed points, the great scholar can always see and note better than we can. It is the obvious things that he cannot see. I do not say this in mere depreciation; I think it is really inseparable from that concentrated research to which the world owes so much. It is the truth in the traditional picture of the absent-minded professor, who remains gazing at a fossil or a Roman coin and fails to observe external objects, such as a house on fire, a revolution, an escaped elephant putting its head through the skylight, and similar things....it is precisely because I am so much less learned than he that it is my privilege to lead him through common ways, pointing out elephants and other enormous objects.
