"The term “assemblage,”, developd by Manuel DeLanda in his book, A New Philosophy of Society, and the ideas behind it, are drawn largely from Deleuze, and Deleuze and Guattari; though DeLanda does not merely repeat Deleuze, but reformulates his arguments (and terminology) in some very crucial ways."

Context within the philosophical debate about entities and relations
From a commentary at http://www.shaviro.com/Blog/?p=541
"Traditionally, positivist, atomistic thought has pretty much denied the importance of relations between entities: the entities themselves are the absolutes, and all relations between them are merely accidental. Thus neoclassical economics adopts a “methodological individualism” according to which “all that matters are rational decisions made by individual persons in isolation from one another” (4). On the other hand, what DeLanda calls the “organismic metaphor” (8) asserts that entities are entirely defined by the totality to which they belong, entirely constituted by their relations: “the basic concept in this theory is what we may call relations of interiority: the component parts are constituted by the very relations they have to other parts in the whole” (9). Hegelian thought is the most powerful example of this tendency, thought Saussurean linguistics and the “structuralism” influenced by it could also be mentioned.
Now, the partisans of both these views usually claim that the two opposed positions are the only possible ones: there are no alternatives. Partisans of methodological individualism simply deny the existence of units larger (or smaller, for that matter) than that of the “individual” (or at most, the patriarchal nuclear family): they see such formations as being metaphysical abstractions with no objective validity. Hence Margaret Thatcher’s notorious statement: “There is no such thing as society. There are only individuals and families.” Of course such “methodological individualism” is absurd, since it is contradicted by everything in our minute-to-minute and day-by-day experience. We are never as isolated as methodological individualism assumes, and we probably couldn’t survive for very long if we were. The very fact that we use language, that we use tools and techniques that we didn’t invent from scratch ourselves, let alone that we use money and engage in acts of exchange, belies the thesis. It’s a curious paradox that the most rabid partisans of methodological individualism tend to be free-market economists and rational-choice political scientists and sociologists, since their entire logic depends upon denying the very factors that make their arguments possible in the first place. But if you press the more intelligent methodological individualists, they will admit that their presuppositions are, indeed, “methodological” rather than ontological, that they represent a kind of abstraction, and that such a methodology, and such an abstraction, are necessary in order to avoid getting stuck in top-down, totalizing theories (their aversion to which is often justified with citations from Karl Popper, Isaiah Berlin, or Friedrich Hayek on the dangers of totalitarianism).
But on the other side of the divide, Hegelians and other proponents of the “organismic metaphor” are just as insistent that their systematic (or “dialectical”) ways of doing things are the only alternatives to the absurdities of atomistic reductionism. I can’t tell you how many arguments I’ve had with Marxists, Zizekians, and others over the years, who insist that my Deleuze-inspired objections to the very notion of totalization, or to the idea that events occur only through a dialectic of negativity (usually up to and including the “negation of the negation”), is untenable: they claim that, to reject these “relations of interiority” is ipso facto to lapse into the absurdities of positivism and atomistic reductionism. The same is true for partisans of various sorts of systems theory (all the way from followers of Niklas Luhmann, to devotees of the Lacanian Symbolic order), who tell me that I cannot escape their system, because anything I say against it already presupposes it, and is already positioned somewhere within it. (Hardcore deconstructionists, despite their denial of the very possibility of totalization or a coherent system, are nonetheless also in this camp: as they argue — just like Lacanians — that one can never escape the presuppositions and aporias of Language. Deconstruction is entirely a theory of relations of interiority, even though it recognizes that such relations are never completed but always still in process).
What DeLanda says — which is indeed what Deleuze said before him — is that we need not accept either term of this binary (nor need we be stuck in the aporia of shuttling endlessly between them). What Deleuze and DeLanda offer instead is not the golden mean of a “Third Way,” but rather a move that is oblique to the very terms of the opposition."
