The doctor nodded curtly. He loved Reed as he would have loved a son of his own, and it hurt him to put into words even the possibility.

"It is in the limits of the possible," he answered.

Again the tramp across the floor and back again. Then Brenton burst out fiercely.

"And I can sit here and whimper about my fate, that I am the square peg in the round hole, while he—Doctor Keltridge, you don't mean it has come to that?"

"Not yet. I only said, what we all must know, that it is on the cards. No one can tell whether they will turn up, or down. Of course, the fact that the rallying comes so slowly is bound to make us fear that the injury was worse than we thought at first. On the other hand, it is almost out of the question to judge it with any accuracy. Do what we will, we can't get inside Reed's body, and see for ourselves just what reactions, if any, are going on in there. I wonder, Brenton," the doctor faced him steadily; "if ever it has occurred to you that, in the last analysis, pure science is often baffled by the personal equation which comes into it, which defies all analysis, and which upsets the whole of our calculations. If it were not for the fact that Reed's ego is his own property, not ours, we could have settled this point about his future, months on months ago. Beyond a certain limit, though, there is no way for us to tell how far he responds to our experimental treatment. If his muscles do twitch, well and good. If they almost twitch and don't, no mortal mind outside of his can reckon how wide the falling short has been. You can talk about pure, abstract, impersonal science, till the moon turns to an Edam cheese. You can no more grasp the initial fact of what that science really is, than you can follow the example of the athletic cow. There's always the distorting lens of one's own mind to be taken into consideration; quite often there's another fellow's: the eye-piece of the compound microscope, and the objective. Take them away, and what impression do you get?" The doctor pulled himself abruptly out of his harangue. "You can't get any science, without the muddling addition of an ego, Brenton; and, moreover, there's a tentacle or two of every ego that sticks out beyond the edges of the law, and demands a separate code for its own management. It is in framing that separate code that we all fall down."

But, to his regret, Brenton was deaf to his harangue.

"You think," he was repeating; "that it may end in that?"

The doctor ruffled his hair until it stood on end, rampant and tousled as a corn-husk mat.

"Good Lord, man! A doctor doesn't think things," he said, with sudden ire. "Moreover, if he did, he wouldn't say them out. Else, where would his patients be? You can frighten any man to death, by offering him a premature glimpse into the next decade. One day at a time is enough for most of us; more than some of us can manage. As for Reed, it is impossible to testify at present; in the end, I fancy, he will be the chief witness for the defence. Meanwhile, he's game. You don't find him maundering supinely about his latter end. No! Do sit down. That wasn't a back-hander, aimed at you, Brenton. I hit straight, or not at all. I wish I could give you a tonic that would take away a little of your blamed self-sensitiveness, if I can coin the term. You're as unselfish as the rest of them, until you get hold of a bit of impersonal slander. Then you seize it in your arms, and hold it on your mental stomach like a mustard plaster. It doesn't do any good, though. It hurts like thunder in the time of it, and it plays the deuce with your later digestion."

Obediently Brenton sat down; or, to speak more accurately, was borne down by the weight of the doctor's energetic denunciation. It was the first time that he had found the doctor in such a mood as that. Mercifully, Brenton had no inkling that he had brought it on himself by his prelude to the talk. It would have shocked him unspeakably, had it dawned upon him that Doctor Keltridge, within himself, was applying profane adjectives to the spiritual doubtings of his rector. It would have astounded him beyond all words, had he known how trivial to the doctor's seasoned mind had seemed his own juggling touch upon the rival claims of Tweedledum and Tweedledee. Had Brenton held within himself one tenth of Reed Opdyke's staying power, all would have come out right in the end. The pieces of the puzzle would have fallen into their true places. Instead, Scott Brenton, in his impatience, was apparently determined to chop the pieces into smaller bits, and then to deface their surfaces almost past recognition. Therefore it had seemed to Doctor Keltridge the one way of escape from the whole pother had been opened by his words, which he now repeated with a fresh emphasis that he hoped would finally impress them upon Scott Brenton's ear.
