I remember, however, remarking on the criminal futility of the whole thing, doctrine, action, mentality; and on the contemptible aspect of the half-crazy pose as of a brazen cheat exploiting the poignant miseries and passionate credulities of a mankind always so tragically eager for self-destruction. That was what made for me its philosophical pretences so unpardonable. Presently, passing to particular instances, we recalled the already old story of the attempt to blow up the Greenwich Observatory; a blood-stained inanity of so fatuous a kind that it was impossible to fathom its origin by any reasonable or even unreasonable process of thought. For perverse unreason has its own logical processes. But that outrage could not be laid hold of mentally in any sort of way, so that one remained faced by the fact of a man blown to bits for nothing even most remotely resembling an idea, anarchistic or other. As to the outer wall of the Observatory it did not show as much as the faintest crack.

I pointed all this out to my friend who remained silent for a while and then remarked in his characteristically casual and omniscient manner: `Oh, that fellow was half an idiot. His sister committed suicide afterwards.' These were absolutely the only words that passed between us; for extreme surprise at this unexpected piece of information kept me dumb for a moment and he began at once to talk of something else. It never occurred to me later to ask how he arrived at his knowledge. I am sure that if he had seen once in his life the back of an anarchist that must have been the whole extent of his connection with the underworld. He was, however, a man who liked to talk with all sorts of people, and he may have gathered those illuminating facts at second or third hand, from a crossing-sweeper, from a retired police officer, from some vague man in his club, or even perhaps from a Minister of State met at some public or private reception.

Of the illuminating quality there could be no doubt whatever. One felt like walking out of a forest on to a plain - there was not much to see but one had plenty of light. No, there was not much to see and, frankly, for a considerable time I didn't even attempt to perceive anything. It was only the illuminating impression that remained. It remained satisfactory but in a passive way. Then, about a week later, I came upon a book which as far as I know had never attained any prominence, the rather summary recollections of an Assistant Commissioner of Police, an obviously able man with a strong religious strain in his character who was appointed to his post at the time of the dynamite outrages in London, away back in the eighties. The book was fairly interesting, very discreet of course; and I have by now forgotten the bulk of its contents. It contained no revelations, it ran over the surface agreeably, and that was all. I won't even try to explain why I should have been arrested by a little passage of about seven lines, in which the author (I believe his name was Anderson) reproduced a short dialogue held in the Lobby of the House of Commons after some unexpected anarchist outrage, with the Home Secretary. I think it was Sir William Harcourt then. He was very much irritated and the official was very apologetic. The phrase, amongst the three which passed between them, that struck me most was Sir W. Harcourt's angry sally: `All that's very well. But your idea of secrecy over there seems to consist of keeping the Home Secretary in the dark.' Characteristic enough of Sir W. Harcourt's temper but not much in itself. There must have been, however, some sort of atmosphere in the whole incident because all of a sudden I felt myself stimulated. And then ensued in my mind what a student of chemistry would best understand from the analogy of the addition of the tiniest little drop of the right kind, precipitating the process of crystallization in a test tube containing some colourless solution.

It was at first for me a mental change, disturbing a quieted-down imagination, in which strange forms, sharp in outline but imperfectly apprehended, appeared and claimed attention as crystals will do by their bizarre and unexpected shapes. One fell to musing before the phenomenon - even of the past: of South America, a continent of crude sunshine and brutal revolutions, of the sea, the vast expanse of salt waters, the mirror of heaven's frowns and smiles, the reflector of the world's light. Then the vision of an enormous town presented itself, of a monstrous town more populous than some continents and in its man-made might as if indifferent to heaven's frowns and smiles; a cruel devourer of the world's light. There was room enough there to place any story, depth enough for any passion, variety enough there for any setting, darkness enough to bury five millions of lives.
