Affect (philosophy)

"Affect" (latin affectus) is a concept used in philosophy by Spinoza and Deleuze. According to Ethics III, 3, Definition 3, an affect is an empowerment, and not a simple change or modification. Affects, according to Deleuze, are not simple affections, as they are independent from their subject. Artists create affects, "blocks of space-time", whereas science works with percepts, according to Deleuze, and philosophy creates concepts.
