Our contemporary horror stories are written in a world where there seems little faith, lost hope, and no salvation. All that remains is the fragmentary and occasionally lyrical testimony of the human being struggling to confront its lack of reason for being in the vast cosmos. This is the terrain of the horror genre.
Eugene Thacker explores this situation in Tentacles Longer Than Night. Extending the ideas presented in his book In The Dust of This Planet, Thacker considers the relationship between philosophy and the horror genre. But instead of taking fiction as the mere illustration of ideas, Thacker reads horror stories as if they themselves were works of philosophy, driven by a speculative urge to question human knowledge and the human-centric view of the world, ultimately leading to the limit of the human—thought undermining itself, in thought.
Tentacles Longer Than Night is the third volume of the "Horror of Philosophy" trilogy, together with the first volume, In The Dust of This Planet, and the second volume, Starry Speculative Corpse.
