“Delighted, of course,” said a young voice, the unmistakable voice of the Isis, and I realized that the door had been opened, not by the decorous little servant girl, but by one of our hosts in person. He was a short, but shapely young gentleman, with curly dark hair and a square, snub-nosed face. He wore slippers and a sort of blazer of some incredible college purple. “This way,” he said; “mind the steps by the staircase. This house is more crooked and old-fashioned than you would think from its snobbish exterior. There are quite a lot of odd corners in the place really.” “That,” said Rupert, with a savage smile, “I can quite believe.” We were by this time in the study or back parlour, used by the young inhabitants as a sitting-room, an apartment littered with magazines and books ranging from Dante to detective stories. The other youth, who stood with his back to the fire smoking a corncob, was big and burly, with dead brown hair brushed forward and a Norfolk jacket. He was that particular type of man whose every feature and action is heavy and clumsy, and yet who is, you would say, rather exceptionally a gentleman. “Any more arguments?” he said, when introductions had been effected. “I must say, Mr Grant, you were rather severe upon eminent men of science such as we. I've half a mind to chuck my D.Sc. and turn minor poet.” “Bosh,” answered Grant. “I never said a word against eminent men of science. What I complain of is a vague popular philosophy which supposes itself to be scientific when it is really nothing but a sort of new religion and an uncommonly nasty one. When people talked about the fall of man they knew they were talking about a mystery, a thing they didn't understand. Now that they talk about the survival of the fittest they think they do understand it, whereas they have not merely no notion, they have an elaborately false notion of what the words mean. The Darwinian movement has made no difference to mankind, except that, instead of talking unphilosophically about philosophy, they now talk unscientifically about science.” “That is all very well,” said the big young man, whose name appeared to be Burrows. “Of course, in a sense, science, like mathematics or the violin, can only be perfectly understood by specialists. Still, the rudiments may be of public use. Greenwood here,” indicating the little man in the blazer, “doesn't know one note of music from another. Still, he knows something. He knows enough to take off his hat when they play 'God Save the King'. He doesn't take it off by mistake when they play 'Oh, Dem Golden Slippers'. Just in the same way science--” Here Mr Burrows stopped abruptly. He was interrupted by an argument uncommon in philosophical controversy and perhaps not wholly legitimate. Rupert Grant had bounded on him from behind, flung an arm round his throat, and bent the giant backwards.
