Of the mass of letters by the same hand that I further turn over too many are of a domestic strain inconsistent with other application; but a page here and there emerges clear, with elements of interest and notes of the characteristic that rather invite than deprecate an emphasis. From these I briefly glean, not minding that later dates are involved--no particular hour at that time being far out of touch with any other, and the value of everything gaining here, as I feel, by my keeping my examples together. The following, addressed to me in England early in '69, beautifully illustrates, to my sense, our father's close participation in any once quite positive case that either one or the other of his still somewhat undetermined, but none the less interesting sons--interesting to themselves, to each other and to _him_--might appear for the time to insist on constituting. William had in '68 been appointed to an instructorship in Psychology at Harvard. He gets on greatly with his teaching; his students--fifty-seven of them--are elated with their luck in having him, and I feel sure he will have next year a still larger number attracted by his fame. He came in the other afternoon while I was sitting alone, and, after walking the floor in an animated way for a moment, broke out: "Bless my soul, what a difference between me as I am now and as I was last spring at this time! Then so hypochondriachal"--he used that word, though perhaps less in substance than form--"and now with my mind so cleared up and restored to sanity. It's the difference between death and life." He had a great effusion. I was afraid of interfering with it, or possibly checking it, but I ventured to ask what especially in his opinion had produced the change. He said several things: the reading of Renouvier (particularly his vindication of the freedom of the will) and of Wordsworth, whom he has been feeding on now for a good while; but more than anything else his having given up the notion that all mental disorder requires to have a physical basis. This had become perfectly untrue to him. He saw that the mind does act irrespectively of material coercion, and could be dealt with therefore at first hand, and this was health to his bones. It was a splendid declaration, and though I had known from unerring signs of the _fact_ of the change I never had been more delighted than by hearing of it so unreservedly from his own lips. He has been shaking off his respect for men of mere science as such, and is even more universal and impartial in his mental judgments than I have known him before.
