In philosophy, facticity (French: facticité, German: Faktizität)[1] has multiple meanings — from "factuality" and "contingency" to the intractable conditions of human existence.
In the mid-20th century works of French existentialists Jean-Paul Sartre and Simone de Beauvoir, facticity signifies all of the concrete details against the background of which human freedom exists and is limited.
Facticity is a term that takes on a more specialized meaning in 20th century continental philosophy, especially in phenomenology and existentialism, including Edmund Husserl, Martin Heidegger, Jean-Paul Sartre, Maurice Merleau-Ponty and Theodor Adorno.
Recent philosophers such as Giorgio Agamben, Jean-Luc Nancy, Byung-Chul Han and François Raffoul have taken up the notion of facticity in new ways.
[citation needed] Facticity plays a key part in Quentin Meillassoux's philosophical project to challenge the thought-world relationship of correlationism.
