The architecture of Deleuze’s theory of virtual genesis, quasi-causality, and Spinoza’s natura naturans/naturata is a remarkably well-constructed whole. Compressing such ideas into a book of only 164 pages is, in itself, a titanic achievement.
Out of This World by Peter Hallward is therefore far from an easy read, but it remains an impressive project: one that seeks to follow Deleuze’s philosophy rigorously within its own logic. I first encountered it through Žižek, who in several of his works - notably Less Than Nothing and Organs Without Bodies (the introduction to the later edition) - refers to Hallward’s analysis. One does not have to fully endorse Deleuze in order to appreciate him. As Hallward himself insists in his conclusion: “Before you disagree with a work that is worthy of disagreement, you have to admire it and rediscover the problems that it poses.” (p. 159)
Deleuze does not use categories of German Idealism such as negativity, dialectical materialism, Aufhebung, or even the death drive. Instead, he takes a different path, one deeply inspired by Spinoza and Bergson. From this foundation he develops concepts such as the Body without Organs, the (positive) immanent virtual field of differentiation, and most decisively: the virtual as a primordial totality.
The virtual is nothing other than pure difference: an infinite variation without causality, perceptible only as difference itself.
The virtual pure past is not measurable or observable, but functions solely as difference. Here, an intriguing link emerges with Fichte’s Tat-Handlung - the causa sui, the “I that posits itself in itself” - as an authentic act (passage à l’acte), a founding gesture that retroactively creates its own precursor (the quasi-cause). Freedom, in this sense, is always retroactive.
Dark Precursor: “This virtual object or precursor conceals itself and its functioning in the actual field or series that it differs. Its own invisible path becomes visible only in reverse …” (p. 49)
“A creating is an effect that becomes irreducible to its cause.” (p. 41)
At this point Deleuze comes close to themes that we also encounter in Žižek and Lacan: the objet petit a, the death drive, that element which always divides itself and never coincides with itself: a thought traceable back to Heraclitus and echoed in Beckett, Schelling (Vanishing Mediator), .... (which you can read in Žižek's works).
This trajectory leads to Deleuze’s notion of Univocity: the ultimate coincidence of signifier and signified. No longer is there any distinction between for-itself and in-itself; the subject itself disappears and becomes asubjective, a Body without Organs.
The central question for Deleuze is: how can we once again become a CREATIVE field of immanence, a Body without Organs?==> His answer is deterritorialisation/ Counter - Actualisation.
This includes the logic of creative subtraction (resonant with Badiou) and the question of how one might become anorganic, asignificant, unlived, larval. In short: how can one divest oneself of the subject in order to become asubjective?
==> The abstract line here functions as a concept of non-division, of taking no place in space, dissolving boundaries without limit.
==> Or, in Deleuze’s famous contrast, as the rhizome against the tree (a form of tendential disembodiment).
==> The figure of the nomad is particularly compelling: the virtual nomad is not bound to land or symbolic order, has no place in history, and emerges from nowhere. “… the nomads have no history; they have only a geography.” (p. 101)
==> or the symbole of the Rhizome in contrast to the Tree (tendential disembodiment).
==> For readers familiar with Hegelian, Žižekian, or Lacanian contexts, this resonates with notions of drive, subjective destitution, and radical self-abolition (COGITO, the ZERO-Level of subjectivity).
==> For Deleuze, all of this falls under the heading of deterritorialisation.
These metaphors are what make Deleuze so fascinating.
What makes Hallward’s book especially valuable is that it has enriched my own understanding of Hegel and Žižek. The parallels and contrasts – which Deleuze himself would almost certainly deny – nevertheless open a space for greater depth. They point toward that eternal idea which continually resurfaces/resurrects (as a 'Difference and Repetition'): the very core of Deleuze’s thought.
Of course, Out of This World remains dense – it is not a book one can skim. Yet unlike some academic philosophical texts that verge on the unreadable, Hallward’s study remains accessible, provided one approaches it through slow, deliberate reading.
I was fortunate to have some prior background through Žižek, especially his Organs Without Bodies, which I still regard as a masterpiece. That preparation allowed me to follow Hallward more closely.
In the end, Out of This World is a true enrichment for my bookshelf: a work to which I will return. Deleuze himself remains unfortunately notoriously difficult, but Hallward offers an invaluable alternative: a study rich with quotations and references that invite the reader back to the original texts.
