Dilemma

Is the physical world fully real?

Realists, idealists, and relationalists divide on whether matter exists mind-independently, derivatively, or as a pattern of relations. The split runs deeper than any single scientific question.

Context

The realism-idealism dispute is one of the oldest in philosophy and has new analogues in contemporary debates about quantum measurement, the simulation hypothesis, and the ontology of computation. Some traditions take the physical world to be mind-independent and fully real. Others hold that it is real but sustained — by mind, by divine attention, by an underlying computational or informational layer. Still others read reality as a pattern of standing relations rather than as substance at all. And cyclical cosmologies relativise the question to the present cosmic round.

Why it matters

What kind of reality matter has shapes the metaphysics of science (does physics describe the world or our best model of it?), the theology of creation (is the world the bedrock of God's act or a sustained appearance?), the ethics of how we treat material things, and the seriousness we give to apparently mind-dependent or simulation-style framings.

The stances

Yes — the physical world is fully real, mind-independent, persisting.

117 schools

On this view, the physical world exists as it is whether anyone observes it or not. Its reality is not derivative on mind, model, or relation; matter is itself the kind of thing that has standing. Whether grounded in a creator's act or in the brute structure of nature, matter is real, substantival, and conserved.

Why these schools land herematter_conservation=Conserved + matter_ont_status=Substantival gathers the realist and theistic-realist cluster: Naturalism, Realism, Materialism, Determinism, Empiricism, OOO, Hylomorphism, Critical Realism, Analytic Metaphysics, Dialectical Materialism, plus Catholic, Reformed, Lutheran, Eastern Orthodox, LDS, Islamic, Jewish, Bahá'í, Zoroastrianism, Manichaeism. The cluster is uniformly comfortable saying that matter is there in its own right.

Real but sustained — not mind-independent in the strict realist sense.

47 schools

On this view, the physical world is real enough — it has its own laws, its own conservation principles, its own resistance to wish — but it is not the floor of being. It is sustained by something else: mind, divine attention, computational substrate, or the patterning of conditions. Strict mind-independence overstates what is the case; pure illusion understates it.

Why these schools land herematter_conservation=Conserved + matter_ont_status=Emergent picks up the dependent-origination cluster (Buddhism, Yogācāra, Mādhyamaka, Pure Land, Vajrayāna), the naturalist-emergence cluster (Pragmatism, Phenomenology, Constructivism, Postmodernism, Existentialism, Logical Positivism), and the idealist-leaning / informational cluster (Idealism, Dataism, Transhumanism, Simulation Theory, Gamer, Quantum Realism, Multiverse, Eternalism). They share the structure: matter is real-as-sustained, not real-as-bedrock.

Real as relations — neither pure substance nor pure construction.

33 schools

On this view, the physical world is real, but its reality is the reality of a pattern: the standing relations among things, processes, and ancestors. Asking whether matter is mind-independent imposes a substance-language the view doesn't accept. What is real is the relational fabric; matter is one of the ways that fabric shows up.

Why these schools land herematter_conservation=Conserved + matter_ont_status=Relational gathers Process Theology, Process Philosophy, Animism, ATR/Yoruba-Ifá, Ubuntu, Deep Ecology, Shintoism, Confucianism, and Taoism. The cluster reads reality as a pattern of relations rather than as a heap of substances; matter is the name we give to certain stable nodes in that pattern.

Real for this cycle — the deepest reality cycles through creation and dissolution.

9 schools

On cyclical views, the physical world is real now, in this cosmic round. Its reality is not eternal; matter emerges from a deeper source and will return to it. The realism-idealism dispute, framed as a once-for-all metaphysical question, is answered at the cosmic-round scale rather than at the absolute one.

Why these schools land herematter_conservation=Non-conserved + matter_ont_status=Emergent gathers Sikhism, Sufism, Hermeticism, Neo-Platonism, Advaita Vedānta, Hinduism's cyclic cosmology, plus Psychedelic/Entheogenic and Afrofuturism in their more cosmological registers. Reality, on these views, is real for this round; the deeper structure is the cycle itself.

Schools the coordinates don't place

These schools don't satisfy any stance's coordinate pattern strongly enough to be assigned — either because they decline to commit on the question (Confucianism is famously silent on what comes after; Pyrrhonian and pragmatist traditions suspend judgment), or because their attribute signature crosses categories in a way the five buckets don't capture.
