I have found that then is no ingredient of the race which I do not possess in either a small way or a large way.

When it is small, as compared with the same ingredient in somebody else, there is still enough of it for all the purposes of examination.

In my contacts with the species I find no one who possesses a quality which I do not possess.

The shades of difference between other people and me serve to make variety and prevent monotony, but that is all; broadly speaking, we are all alike; and so by studying myself carefully and comparing myself with other people, and noting the divergences, I have been enabled to acquire a knowledge of the human race which I perceive is more accurate and more comprehensive than that which has been acquired and revealed by any other member of our species.

As a result, my private and concealed opinion of myself is not of a complimentary sort.
