If perception and language objectivate the world, if imagination structures it, if knowledge orders it, then how can we describe, name, or even apprehend that which comes to pass when language is absent, when perception vacillates, and when knowledge eludes us? How can we say, show, or make known that which undermines and refutes the order of things, the supposedly immutable real, and the administration of the sensible?

This book takes us on a quest that traverses philosophy and the human sciences, but also literature, cinema, and the visual arts. Not content with analysing the ordering power of our representations, in The Infra-World François J. Bonnet also interrogates the works of artists who have experienced and experimented with those moments when they crack open, giving way to anguish and vertigo.

If perception is a sieve, what can be said of that which slips through its net, how does one speak of what escapes? What remains of unqualified perceptions, of vanishing sensations? Where do the indescribable, nocturnal fears hide, the horrors lurking behind closed eyes? What of the world beneath language and objectivated sensation? What of the infra-world?
