Dependent co-arising (Sanskrit: pratītyasamutpāda) is the central ontological doctrine of Buddhist philosophy, articulated most rigorously by the second-century philosopher Nāgārjuna. It holds that nothing possesses svabhāva — self-nature — no thing exists by its own power, from its own side, independent of the conditions that give rise to it. Everything arises in dependence on other things, which themselves arise in dependence on further things, in a web of mutual conditioning with no first cause and no unconditioned ground. Macy's doctoral work traced the structural parallel between this ancient Buddhist insight and the cybernetic concept of feedback, arguing that two traditions separated by twenty-five centuries had arrived at the same view of reality through different methods. The convergence, she argued, is diagnostic of the reality itself.
Nāgārjuna's articulation in the Mūlamadhyamakakārikā (Fundamental Verses on the Middle Way) demolishes the notion of independent existence through a systematic logical analysis. Every entity, every property, every event is shown to depend on conditions outside itself for its existence as the thing it is. The flame depends on the wick, the wick depends on the wax, the wax depends on the bee, and so on without terminus. The doctrine is not a claim about causation in the Western sense; it is a claim about the structure of existence itself.
Applied to AI collaboration, dependent co-arising illuminates why the authorship question feels intractable. The thought that emerges in a human-AI dialogue does not have a single origin because the thinking is itself a co-arising — the human's question shaped by expectations of the machine, the machine's response shaped by training data produced by many humans, the human's revised question shaped by the response, in a chain of dependence with no independent originator.
The doctrine has ethical weight in Buddhist practice. Because nothing exists independently, the suffering of any being is structurally connected to the conditions affecting all beings. The bodhisattva vow to work for the liberation of all sentient beings is grounded in this ontology: the vow is not altruism added to self-interest but the accurate response to the perception that self and other are co-arising configurations of the same dependent pattern.
Macy's innovation was to place the doctrine in dialogue with Western systems thinking, showing that Bateson's ecology of mind and Bertalanffy's general systems theory had independently developed frameworks structurally parallel to Nāgārjuna's. The convergence was not coincidental, Macy argued — it pointed to the reality of mutual causation as a feature of living systems.
The doctrine is articulated in numerous Buddhist sutras and was developed philosophically by Nāgārjuna in the second century CE. Macy's synthesis with systems theory was her doctoral contribution, refined across decades of both scholarly and contemplative practice.
No self-nature. Nothing possesses independent, self-sustaining existence; everything arises in dependence.
The web has no terminus. The chain of dependence does not bottom out in some unconditioned ground; it extends in every direction without end.
Structural parallel with cybernetics. The feedback loops of living systems exhibit the same non-linear, mutually-constituting structure the doctrine describes.
Ethical implications. The perception of dependent co-arising grounds the bodhisattva commitment to the liberation of all beings as accurate response rather than altruistic addition.
Diagnostic convergence. Two traditions arriving independently at the same ontological insight suggests the insight tracks reality rather than reflecting cultural construction.
Contemporary Buddhist philosophers have debated whether Macy's synthesis with systems theory is faithful to Nāgārjuna's more radical ontology — whether the cybernetic framework preserves the full weight of the doctrine's refusal of substance. Macy acknowledged the question and argued that the synthesis illuminates both traditions without reducing either to the other.
