Michael W. Clune on Ligotti (and “the psychology of cosmic horror”):
Things are not what they seem. This is the mantra and the practice of cosmic horror. Lovecraft wrote stories in which familiar appearances — mountains, stars, old New England houses — melt away from things that now wear an unspeakably different aspect. While the focus in Lovecraft is always on the alien reality below the appearances, Ligotti is fascinated by the simple capacity of changing appearances to suggest a different reality. He pursues the inhumanist psychology of the process in which appearances come loose from their anchor in the human world.
