But, as I said at the outset, the paramount thing in Davidson in my eyes was his capacity for friendship. His friends were innumerable--boys and girls and old boys and old girls, Papists and Protestants, Jews and Gentiles, married and single; and he cared deeply for each one of them, admiring them often too extravagantly. What term can name those recurrent waves of delighted laughter that expressed his greeting, beginning from the moment he saw you and accompanying his words continuously, as if his pleasure in you were interminable? His hand too, stretched out when yards away, so that a country neighbor said it reached farther than any hand he ever met with. The odd thing was that friendship in Davidson seemed so little to interfere with criticism. Persons with whom intercourse was one long contradiction on his part, and who appeared to annoy him to extermination, he none the less loved tenderly, and enjoyed living with them. "He's the most utterly selfish, illiberal and narrow-hearted human being I ever knew," I heard him once say of someone, "and yet he's the dearest, nicest fellow living." His enthusiastic belief in any young person who gave a promise of genius was touching. Naturally a man who is willing, as he was, to be a prophet, always finds some women who are willing to be disciples. I never heard of any sentimental weakness in Davidson in this relation, save possibly in one case. They harmed themselves at the fire of his soul, and he told them truths without accommodation. "You 're farther off from God than any woman I ever heard of." "Nay, if you believe in a protective tariff, you 're in hell already, though you may not know it." "You had a fine hysterical time last night, didn't you, when Miss B was brought up from the ravine with her dislocated shoulder." To Miss B he said: "I don't pity you. It served you right for being so ignorant as to go there at that hour." Seldom, strange to say, did the recipients of these deliverances seem to resent them. What with Davidson's warmth of heart and sociability, I used to wonder at his never marrying. Two years before his death he told me the reason--an unhappy youthful love-affair in Scotland. Twice in later life, he said, temptation had come to him, and he had had to make his decision. When he had come to the point, he had felt each time that the tie with the dead girl was prohibitive. "When two persons have known each other as we did," he said, "neither can ever fully belong to a stranger. So it would n't do." "It would n't do, it would n't do!" he repeated, as we lay on the hillside, in a tone so musically tender that it chimes in my ear now as I write down his confession. It can surely be no breach of confidence to publish it--it is too creditable to the profundity of Davidson's affections. As I knew him, he was one of the purest of human beings.
