Foundations of the Ontology of Emergent Complexity/Philosophical Commitments/Against the Invention of Two Worlds

1.2 – Against the Invention of Two Worlds Several influential Western philosophical lineages have organised intelligibility through a hierarchy between ideal and material orders. Plato’s distinction between intelligible Forms and the sensible world and Descartes’s distinction between res cogitans and res extensa exemplify different versions of that operation (Plato 1997, 1132, 1259; Descartes 1996, 26, 59). They neither exhaust Western thought nor constitute a single doctrine. The narrower claim is that, where meaning, value, or intelligibility is assigned its source or final measure in an order not exhausted by mutable material processes, contingency, opacity, and error tend to acquire a subordinate status. In the cases examined here, this hierarchy does more than distinguish domains. It can perform a symbolic stabilising function by placing the source or measure of truth beyond material transformation. The argument is not that every appeal to form or intelligibility constitutes an escape from matter. It is that a duplicated ontology becomes explanatorily incomplete when material processes and symbolic efficacy can be understood only by reference to a superior order whose relation to those processes remains unexplained. The asymmetry is explicit in some traditions, but it does not take the same form in all of them. Plotinus organises reality through a vertical hierarchy articulated by procession from and return to the One (Plotinus 1966, 198). Hegel cannot be assimilated to a simple two-world architecture: dialectical mediation seeks to overcome fixed oppositions within a systematic movement. The disagreement developed here concerns instead the teleological orientation and final integration associated with absolute knowing, not the postulation of a separate intelligible realm (Hegel [1807] 1977, 27, 45). Kant also requires a different treatment. The noumenon marks a limit of cognition rather than a superior world available to knowledge, and transcendental idealism does not make empirical experience merely illusory. The question raised from the present framework is whether the formal conditions assigned to possible experience have themselves been sufficiently located in material organisation (Kant [1781] 1998, 360). A more difficult question concerns thinkers who explicitly displace classical metaphysics. Heidegger’s ontological difference is not a second substance; Levinas’s alterity is not an object placed in another world; Derrida’s trace contests the ideal of pure presence (Heidegger [1927] 1962, 41; Levinas [1961] 1969, 77; Derrida [1967] 1997, 71). The question is not whether these concepts simply reproduce a two-world ontology. It is whether the material supports, relations, and effects through which they become operative have been sufficiently specified. Where those conditions remain unspecified, the present framework regards the explanation as incomplete; it does not thereby classify these thinkers as classical dualists. The ontology developed here rejects the explanatory need for a second domain. No difference or alterity must be exempted from material relations in order to be real, and no ontological tier is immune to material conditions and transformation. Emergence is not the appearance of a higher order within a lower one. According to an explicit criterion, materially realisable relations may exceed the relations realised in the present symbolic or structural form, thereby making reconfiguration possible. Whether reconfiguration occurs and which configuration results depend on the full set of materially active relations. A new property or capacity counts as emergent only when it becomes operative and is established through its material effects. Differences among physical, living, and symbolic regimes remain real without becoming differences between separate worlds. There are not two worlds. There is one heterogeneous spatiotemporal material reality, without ontological exterior or final ground, and no second world is required to explain what emerges within it. Reading Colloquium This guide accompanies the argument; it does not replace it. 1. Placement of the Text within the Architecture of the Work This section develops a specific consequence of the refusal of metaphysical dualism established in §1.1. The previous section rejected explanations that grant priority to a domain outside spatiotemporal material reality. Section 1.2 examines how some philosophical doctrines construct two ordered domains — one assigned explanatory or normative priority, the other treated as derivative, mutable, or deficient. The section does not claim that this structure exhausts Western philosophy, that every distinction creates two worlds, or that all the thinkers discussed reproduce the same architecture. Its function is diagnostic: to identify cases in which an ideal or intelligible order placed outside or above spatiotemporal material reality becomes its source, ground, or final measure. 2. Philosophical Problem at Stake The problem is not simply whether a distinction between ideal and material orders is true or false. It concerns the explanatory work performed by that distinction. In the cases examined, the superior order can stabilise intelligibility by placing its source or measure beyond material contingency and transformation. Material processes are then interpreted by reference to an order treated as exempt from material conditions and granted explanatory or normative priority over them. Calling this division an “invention” does not mean that it is an arbitrary fiction or that the philosophers concerned were deceptive. It means that the division is a symbolic construction responding to genuine philosophical pressures, including the stability of knowledge, the authority of reason, and the possibility of truth. The relevant question is whether the construction explains material and symbolic processes or transfers the explanatory burden to another domain whose relation to those processes remains unspecified. 3. Core Thesis and Conceptual Reorganisation The core thesis is that a duplicated ontology is not required to explain intelligibility, meaning, or value. The OEC refuses both the priority of an order placed beyond spatiotemporal material reality and the simple inversion of the hierarchy. It does not replace the supremacy of the ideal with the supremacy of an undifferentiated material substance. There is one heterogeneous spatiotemporal material reality within which physical, living, and symbolic organisations can acquire different properties and capacities. Emergence is not the manifestation of something higher within something lower. Operative excess makes reconfiguration possible when, according to an explicit criterion, materially realisable relations exceed the relations realised in the present symbolic or structural form. Emergence is established separately when a materially conditioned reconfiguration occurs and produces a property, capacity, or effect that was not realised by the prior organisation. Its occurrence is verified through the material effects it introduces into the field of possible operations. Contemporary proposals such as modal realism, simulation hypotheses, or ontological interpretations of the multiverse should therefore be examined rather than classified in advance. They reproduce a two-world architecture only if they posit another domain and grant it explanatory priority over the material configuration under consideration. A heuristic model, an epistemic limit, or reference to the material environment of a local organisation does not by itself constitute metaphysical duplication. 4. Key Concepts and Their Articulation Invention of Two Worlds: the symbolic construction of distinct ontological domains when one is made the source, ground, or final measure of the other. Symbolic Hierarchy: an organisation of intelligibility in which one domain governs how another is interpreted, valued, or explained. Emergence: the process in which a materially conditioned reconfiguration occurs and produces a property, capacity, or effect that was not realised by the prior organisation, verified through its material effects. Operative excess makes that reconfiguration possible without making it necessary or determining its result. Rejection of Transcendence: refusal to assign explanatory or normative priority to an order exempted from material conditions and transformation. One Field Without Exterior: the claim that no ontological domain exists outside spatiotemporal material reality. Distinctions between local organisations and their material environments remain entirely internal to that reality. The historical cases must remain differentiated. Plotinus explicitly organises reality through a hierarchy of procession and return. Hegel does not posit a simple second world; the disagreement concerns the teleological orientation and systematic integration associated with absolute knowing. Kant’s noumenon marks a limit of cognition rather than a superior world available to knowledge. Heidegger, Levinas, and Derrida should likewise not be classified as classical dualists. The narrower question is whether the material supports, relations, and effects through which their decisive concepts operate have been sufficiently specified. 5. Implications for Readers and Pedagogical Pathways Readers should not infer a two-world ontology from the mere presence of distinctions, epistemic limits, relations between local organisations and their material environments, or entities that cannot be directly observed. The relevant test concerns explanatory priority: What domains are being distinguished? Is one domain treated as the source, ground, or final measure of the other? Is the relation between that domain and material processes explained? Does the proposal posit a domain beyond spatiotemporal material reality, or only an epistemic limit, a heuristic instrument, or a material environment? Does refusing an ontological exterior preserve real differences among material organisations, or does it flatten them? For classroom or study-group work: Compare the different functions performed by intelligible order in Plato, Plotinus, and Descartes. Explain why Hegel and Kant cannot be treated as straightforward instances of the same two-world architecture. Apply the explanatory-priority test to modal realism, simulation hypotheses, and ontological interpretations of the multiverse without deciding the result in advance. Show how one heterogeneous spatiotemporal material reality can contain distinct physical, living, and symbolic regimes without becoming a flat or homogeneous monism.
