Night was a very different matter. It was dense, thicker than the very walls, and it was empty, so black, so immense that within it you could brush against appalling things and feel roaming and prowling around a strange, mysterious horror.

Daylight does not lend itself to terror: objects and people are plain to see; and we encounter there only those things which dare to show themselves in the glare of day. But night, opaque night denser than walls, night, empty and infinite and so black and fathomless that terrifying things reach out and touch us, night when we feel horror stirring, mysteriously prowling―night seemed to him to hide some unknown, imminent, threatening danger. What could it be?

I love the night passionately... I love it with all my senses: I love to see it, I love to breathe it in, I love to open my ears to its silence, I love my whole body to be caressed by its blackness...

I told myself: 'I am surrounded by unknown things.' I imagined man without ears, suspecting the existence of sound as we suspect so many hidden mysteries, man noting acoustic phenomena whose nature and provenance he cannot determine. And I grew afraid of everything around me – afraid of the air, afraid of the night. From the moment we can know almost nothing, and from the moment that everything is limitless, what remains? Does emptiness actually not exist? What does exist in this apparent emptiness?
