"He asked Arthur Withers what year it was. Naturally, if he did come from the future, his first anxiety would be to know into what period of man's history he had, possibly by some accident, wandered." "But how could he have come from the future?" "Time," said Gregg, quickly, "is a relative thing. The future has happened just as much as the past. It is happening at this moment." "Oh, well, you may be right there," blustered Allingham, "I don't know. I admit I'm not quite up to date in these abstruse speculations." "I regard that statement of his as highly significant," resumed Gregg, after a slight pause. "For, of course, if the Clockwork man really is, as suggested, a semi-mechanical being, then he could only have come from the future. So far as I am aware, the present has not yet evolved sufficiently even to consider seriously the possibility of introducing mechanical reinforcements into the human body, although there has been tentative speculation on the subject. We are thousands of years away from such a proposition; on the other hand, there is no reason why it should not have already happened outside of our limited knowledge of futurity. It has often occurred to me that the drift of scientific progress is slowly but surely leading us in the direction of some such solution of physiological difficulties. The human organism shows signs of breaking down under the strain of an increasingly complex civilisation. There may be a limit to our power of adaptability, and in that case humanity will have to decide whether it will alter its present mode of living or find instead some means of supplementing the normal functions of the body. Perhaps that has, as I suggest, already happened; it depends entirely upon which road humanity has taken. If the mechanical side of civilisation has developed at its present rate, I see no reason why the man of the future should not have found means to ensure his efficiency by mechanical means applied to his natural functions." Gregg sat up in his chair and became more serious. Allingham fidgeted without actually interrupting. "Imagine an exceedingly complex kind of mechanism," Gregg resumed, "an exaggeration of the many intricate types of modern machines in use to-day. It would have to be something of a very delicate description, and yet rather crude at first in its effect. One thinks of something that would work accurately if in rather a limited sort of way. You see, they would have to ensure success in some things at first even at the sacrifice of a certain general awkwardness. It would be a question of taking one thing at a time. Thus, when the Clockwork man came to play cricket, all he could do was to hit the ball. We have to admit that he did that efficiently enough, however futile were the rest of his actions." "Hot air," interrupted Allingham, reaching for his tobacco pouch, "that's all this is."
