"There are no simple concepts. Every concept has components and is defined by them.It therefore has a combination [chiffre]. It is a multiplicity, although not every multiplicityis conceptual...Not only do Descartes, Hegel, and Feuerbach not beginwith the same concept,they do not have the same concept of beginning...Every concept has an irregularcontour defined by the sum of its components,which is why,from Plato to Bergson,we findthe idea of the concept being amatter of articulation,of cutting andcross-cutting.The concept is a whole because it totalizesits components, but it isa fragmentary whole.Only on this condition can it escape themental chaosconstantly threatening it, stalking it, trying to reabsorb it."
