“That Crawford Tilinghast should ever have studied science and philosophy was a mistake. These things should be left to the frigid and impersonal investigator for they offer two equally tragic alternatives to the man of feeling and action; despair, if he fail in his quest, and terrors unutterable and unimaginable if he succeed.”

“In youth he had felt the hidden beauty and ecstasy of things, and had been a poet; but poverty and sorrow and exile had turned his gaze in darker directions, and he had thrilled at the imputations of evil in the world around. Daily life had for him come to be a phantasmagoria of macabre shadow-studies; now glittering and leering with concealed rottenness as in Beardsley's best manner, now hinting terrors behind the commonest shapes and objects as in the subtler and less obvious work of Gustave Dore. He would often regard it as merciful that most persons of high Intelligence jeer at the inmost mysteries; for, he argued, if superior minds were ever placed in fullest contact with the secrets preserved by ancient and lowly cults, the resultant abnormalities would soon not only wreck the world, but threaten the very integrity of the universe. All this reflection was no doubt morbid, but keen logic and a deep sense of humour ably offset it. Malone was satisfied to let his notions remain as half-spied and forbidden visions to be lightly played with; and hysteria came only when duty flung him into a hell of revelation too sudden and insidious to escape.”

“What do we know,” he had said, “of the world and the universe about us? Our means of receiving impressions are absurdly few, and our notions of surrounding objects infinitely narrow. We see things only as we are constructed to see them, and can gain no idea of their absolute nature. With five feeble senses we pretend to comprehend the boundlessly complex cosmos, yet other beings with a wider, stronger, or different range of senses might not only see very differently the things we see, but might see and study whole worlds of matter, energy, and life which lie close at hand yet can never be detected with the senses we have. I have always believed that such strange, inaccessible worlds exist at our very elbows, and now I believe I have found a way to break down the barriers.”

“We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far.”

“Bunch together a group of people deliberately chosen for strong religious feelings, and you have a practical guarantee of dark morbidities expressed in crime, perversion, and insanity.”

“Contrary to what you may assume, I am not a pessimist but an indifferentist- that is, I don't make the mistake of thinking that the... cosmos... gives a damn one way or the other about the especial wants and ultimate welfare of mosquitoes, rats, lice, dogs, men, horses, pterodactyls, trees, fungi, dodos, or other forms of biological energy.”

“Something like fear chilled me as I sat there in the small hours alone-I say alone, for one who sits by a sleeper is indeed alone; perhaps more alone than he can realise.”
