"Man is now a new animal, a new and different animal; he can jump a hundred miles, see through brick walls, bombard atoms, analyse the stars, set about his business with the strength of a million horses. And so forth and so on. Yes. Yes. But all the same he goes on behaving like the weak little needy ape he used to be. He grabs, snarls, quarrels, fears, stampedes, and plays in his immense powder magazine until he seems likely to blow up the whole damned show."
