Professor Chadd appeared totally unmoved, with his face still lifted to the lamp and the wrinkle cut in his forehead.

“Your mental processes,” he said, “always go a little too fast. And they are stated without method. There is no kind of inconsistency”—and no words can convey the time he took to get to the end of the word—“between valuing the right of the aborigines to adhere to their stage in the evolutionary process, so long as they find it congenial and requisite to do so. There is, I say, no inconsistency between this concession which I have just described to you and the view that the evolutionary stage in question is, nevertheless, so far as we can form any estimate of values in the variety of cosmic processes, definable in some degree as an inferior evolutionary stage.”

Nothing but his lips had moved as he spoke, and his glasses still shone like two pallid moons.

Grant was shaking with laughter as he watched him.

“True,” he said, “there is no inconsistency, my son of the red spear. But there is a great deal of incompatibility of temper. I am very far from being certain that the Zulu is on an inferior evolutionary stage, whatever the blazes that may mean. I do not think there is anything stupid or ignorant about howling at the moon or being afraid of devils in the dark. It seems to me perfectly philosophical. Why should a man be thought a sort of idiot because he feels the mystery and peril of existence itself? Suppose, my dear Chadd, suppose it is we who are the idiots because we are not afraid of devils in the dark?”

Professor Chadd slit open a page of the magazine with a bone paper-knife and the intent reverence of the bibliophile.

“Beyond all question,” he said, “it is a tenable hypothesis. I allude to the hypothesis which I understand you to entertain, that our civilization is not or may not be an advance upon, and indeed (if I apprehend you), is or may be a retrogression from states identical with or analogous to the state of the Zulus. Moreover, I shall be inclined to concede that such a proposition is of the nature, in some degree at least, of a primary proposition, and cannot adequately be argued, in the same sense, I mean, that the primary proposition of pessimism, or the primary proposition of the non-existence of matter, cannot adequately be argued. But I do not conceive you to be under the impression that you have demonstrated anything more concerning this proposition than that it is tenable, which, after all, amounts to little more than the statement that it is not a contradiction in terms.”

Basil threw a book at his head and took out a cigar.

“You don't understand,” he said, “but, on the other hand, as a compensation, you don't mind smoking. Why you don't object to that disgustingly barbaric rite I can't think. I can only say that I began it when I began to be a Zulu, about the age of ten. What I maintained was that although you knew more about Zulus in the sense that you are a scientist, I know more about them in the sense that I am a savage. For instance, your theory of the origin of language, something about its having come from the formulated secret language of some individual creature, though you knocked me silly with facts and scholarship in its favour, still does not convince me, because I have a feeling that that is not the way that things happen. If you ask me why I think so I can only answer that I am a Zulu; and if you ask me (as you most certainly will) what is my definition of a Zulu, I can answer that also. He is one who has climbed a Sussex apple-tree at seven and been afraid of a ghost in an English lane.”

“Your process of thought—” began the immovable Chadd, but his speech was interrupted. His sister, with that masculinity which always in such families concentrates in sisters, flung open the door with a rigid arm and said:
