“All I say is that I think it is damned unlikely that anything like a central cosmic will, a spirit world, or an eternal survival of personality exist. They are the most preposterous and unjustified of all the guesses which can be made about the universe, and I am not enough of a hair-splitter to pretend that I don't regard them as arrant and negligible moonshine. In theory I am an agnostic, but pending the appearance of radical evidence I must be classed, practically and provisionally, as an atheist.”

“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.”

“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.”

“In relating the circumstances which have led to my confinement within this refuge for the demented, I am aware that my present position will create a natural doubt of the authenticity of my narrative.”

“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.”

“I couldn't live a week without a private library - indeed, I'd part with all my furniture and squat and sleep on the floor before I'd let go of the 1500 or so books I possess.”

“I have seen the dark universe yawningWhere the black planets roll without aim,Where they roll in their horror unheeded,Without knowledge, or lustre, or name.”
