H. M. to H. G. A.

My dear Friend,

I rather think the reason why we have so much pleasure in talking over, and writing about, the powers and action of men, and the characters of individuals, is, that your observations proceed upon some basis of real science, and that I know that they do; and that thus we are talking to some purpose on those most interesting subjects, instead of theorizing without taking stock of our facts on the one hand, or merely amusing ourselves with desultory observations on the other. I want, however, to look closer into the matter. I want to know precisely what your scientific basis is, instead of merely profiting by your having one, and having a general notion how you came by it. I want you to tell me, with great particularity, (if you will,) how you would have one set about the study of the powers of Man, in order to understand his nature, and his place, business and pleasure in the universe.

For thirty years past I have been disposed to this kind of study; and it is strange to think how many books I have read, and how often over, and what an amount of hours I have spent in thinking, and how many hundreds of human beings I have watched and speculated upon, without being ever, for one moment, satisfied that I knew what I was about,—for want, I suppose, of some scientific basis for the inquiry, and of some laws manifesting themselves in its course;—laws on which one might rest, and to which one might recur, when in perplexity how to proceed.
