To understand why Deleuze and Guattari reject the Freudian and Lacanian model of desire as "lack," one must examine the specific mechanical processes they propose in its place. While traditional psychoanalysis suggests desire is born from a missing object (the mother, the phallus, or the *objet petit a*), *Anti-Oedipus* posits that desire is an immanent, self-sufficient force that requires no external justification or origin.
## The Passive Syntheses of Desire
Deleuze and Guattari detail how desire functions through three **passive syntheses**. These are unconscious processes that build reality before any "ego" or "subject" emerges.
1. **The Connective Synthesis (Production of Production)**: This is the "and... and..." logic of desire. It involves the coupling of "partial objects." For example, the mouth-machine connects to the breast-machine to produce a flow of milk. There is no "person" here, only functional couplings that produce something new.
2. **The Disjunctive Synthesis (Production of Recording)**: This process organizes the various connections onto a surface, which the authors call the **Socius** or the **Body without Organs**. It creates a grid or a map of where flows can go. Unlike traditional logic, which uses "either/or" to exclude (you are either a son or a worker), the "inclusive disjunction" of desire allows for multiple, overlapping identities.
3. **The Conjunctive Synthesis (Production of Consumption)**: Only at this final stage does a "subject" emerge. The subject is not the cause of desire but a residual byproduct—a feeling of "So that’s what I am!" or "So that’s what I was doing!" It is a point of arrival, not a point of departure.
## Desire as a Social Investment
By removing "lack" from the definition of desire, the authors perform a political intervention. If desire is defined by lack, it is inherently dependent on an authority (the Parent, the Priest, or the State) to provide what is missing. This creates a "priestly" psychology of guilt and debt.
Instead, they argue that **desire is directly economic and political**. There is no "private" desire for a mother that is later "sublimated" into a job or a political stance. Rather, the child’s desire is already invested in the social field: the father is not just a parent, but a representative of a specific class, a specific workplace, and a specific history. We do not desire "objects"; we desire **assemblages**. One does not desire a car; one desires the entire social assemblage of the highway, fossil fuels, status, and mobility.
## The Critique of Scarcity
The concept of lack is the foundational myth of market economics. By framing desire as lack, capitalism can maintain the "theatre" of **scarcity**. If we believe we are fundamentally incomplete, we are easily manipulated into seeking completion through consumption.
Deleuze and Guattari suggest that "desiring-production" is actually characterized by **excess**. It is a profligate, overflowing force that capitalism must constantly capture, channel, and restrict to maintain its specific order. The "schizo" as a process represents the moment desire ignores the artificial boundaries of lack and simply continues to connect, produce, and flow.
