The Question Is Not Only Belief or Disbelief

Disputes about God and the soul are usually understood as disagreements between belief and disbelief. Does God exist or not? Do human beings have souls or not? Can the soul continue to exist after bodily death? These are all important questions, but they are not yet the level this essay is primarily concerned with.

The more fundamental question is why two existence claims that have not received final adjudication have nevertheless been able, in several traditions, to shape the basic structure of a philosophical system over long periods. Many systems appear compelled to make an initial choice here. To affirm God is to explain the relation between God and the world, natural law, human freedom, and suffering. To deny God is to explain anew the ultimate ground of the world and the sources of order and value. To affirm the soul is to confront how soul and body are joined, how they interact, and how identity is preserved. To deny the soul is still to explain consciousness, first-person experience, personal continuity, and the unity of a human life.

God and the soul do not perform the same function. God is located primarily at the level of the world as a whole and concerns creation, first cause, ultimate ground, and the guarantee of order and value. The soul is located primarily at the level of individual life and concerns the subject of consciousness, personal identity, moral responsibility, and the possibility of continued existence after death. They are not naturally bound as a conceptual pair, yet at several decisive moments in the history of Western philosophy they have jointly marked the limits of a system. Philosophy has had to decide not only whether to believe in them, but where to place them and whether the entire framework can still stand without them.

The central judgment of this essay is not that Sustenesis Theory has answered whether God and the soul exist. It answers a different question: must a general ontology depend on a prior decision about these two claims? Sustenesis itself provides a clear counterexample.

A Recurrent Tension in the History of Philosophy

This issue should not be exaggerated into the sole cause of the development of philosophy as a whole. Philosophy has also been shaped by natural science, epistemology, logic, language, politics, ethics, social structure, and many other forces. Chinese philosophy, Indian philosophy, and other intellectual traditions cannot be compressed into the same narrative of Western theological history. Nevertheless, within Western metaphysics and the modern philosophy of mind that grew from it, the placement of God and the soul has formed a major structural tension that repeatedly returns.

The ancient Greek concept of soul was not identical with what modern people generally call mind, nor can it be directly equated with the immortal soul of later Christianity. Plato connected the soul with genuine knowledge, the order of the person, and fate after death, and discussed its immortality systematically in the Phaedo. Aristotle understood the soul as the form and principle of life of a living being, not as another thing simply placed inside the body. These two paths already display a difference that would recur: is the soul an existence separable from the body, or the form and capacity of living organization itself?

In many systems of medieval Christian scholasticism, creator, world order, immortality of the soul, moral responsibility, and final salvation were integrated into a comparatively complete theological–philosophical structure. God was not only an object of religious faith, but also performed philosophical functions as the ultimate ground of existence, the source of world order, and the guarantee of truth. The soul became an important condition of the individual’s retention of identity after death and assumption of ultimate responsibility.

With the rise of modern science, the problem did not disappear. It became more acute in new forms. Descartes distinguished thinking substance from extended substance, assigning separate places to the soul and mechanical nature, while also relying on God to guarantee the reliability of clear and distinct ideas. This arrangement preserved the human spiritual subject but left two fundamental difficulties: how can mind and body, whose natures are entirely different, interact, and why does knowledge still require a divine guarantor?

Spinoza did not simply delete God. He understood “God or Nature” as the one substance, with mind and body as expressions of the same existence under different attributes. This did not remove God from the system; it transformed the meanings of God, nature, mind, and body together.

Kant restricted the capacity of theoretical reason to prove God and the immortality of the soul. He no longer treated them as objects directly established by pure speculative knowledge, but retained God and immortality within practical reason as postulates connected with the highest good. This move significantly changed their philosophical position without making the questions disappear. They moved from objects of theoretical knowledge into the structures of moral reason, hope, and belief.

Nietzsche later opposed the eternal, indivisible “soul atom,” yet still allowed discussion of a “mortal soul” and of the soul as a social structure of drives and affects. These precedents show that the history of philosophy has never lacked ways of placing God and the soul. Rather, every placement redefines the relations among existence, nature, personhood, freedom, and value, and carries a different theoretical cost.

Idealism, atheism, naturalism, and physicalism have offered further answers in modern and contemporary philosophy. Modern physicalism attempts to return mind to the physical world and avoid the causal rupture created by an independent mental substance. Reductive physicalism must still explain how consciousness, intentionality, agency, subjectivity, and personal identity can be fully reduced; non-reductive physicalism addresses these issues in other ways. Dualism preserves the irreducibility of mind but must explain the relation between mind and body. The problem persists under changing vocabularies not because philosophers have failed to choose positions, but because each choice changes the explanatory burden the entire system must bear.

This history does not show that God and the soul have determined the whole of philosophy. It is enough to establish a more limited fact: they have long been more than two objects within a system. They have been branching points capable of altering its foundations.

The Difficulty Begins with a Conception of Existence

The difficulty of placing God and the soul is connected with how some philosophical traditions understand existence. If existence is understood primarily in terms of substances with fixed essences, definite boundaries, and independent self-sufficiency, the soul is easily driven toward two extremes. It is either understood as an immaterial substance alongside the body, or denied because it cannot be observed and located as a material object. The first arrangement produces mind–body dualism. Only when the second is joined to strong reductionism does consciousness and the whole person become compressed into physiological processes. Rejecting a substantial soul does not in itself require this result.

God confronts substantialization in the opposite direction. To explain why there is a world, why the world possesses order, and why knowledge can approach truth, philosophy readily places God above all existence as the highest being or first cause. This appears to provide an ultimate ground, but it also makes ontology dependent on an existence more difficult to prove. Once this arrangement is rejected, philosophy is often required to provide an immediate replacement with exactly the same function, as though anything less would leave an unfillable gap.

Across the traditions described above, the two difficulties share a structure: general ontology is repeatedly bound to two specific existence claims. Whether the soul exists is equated with whether an immaterial substance exists; whether God exists is equated with whether the world possesses an ultimate ground. Systems then determine their direction by affirming, denying, or suspending judgment about these two objects.

What Sustenesis Theory changes is not one particular answer, but the binding relation itself.

Sustenesis Begins from the Conditions Under Which Existence Forms

Sustenesis does not begin by asking “what substance exists first?” It begins with the basic conditions under which any existence can form and be maintained. Difference keeps the elements and relations within a structure distinguishable and establishes a boundary between the structure and its environment. Constraint places differences into bounded and directed relations, limiting the possible range of change. Sustained Coherence enables a structure to preserve enough continuity through change, disturbance, and correction to present itself as a recognizable existence at a given scale.

Under the stable definition used by Sustenesis Theory, existence is the stable presentation of a sustenetic structure at a given scale: the Sustained Coherence that a structure maintains through change. Stability here does not mean stasis. A living organism continually exchanges matter, a person continually gains experience, and an institution continually changes participants; each may nevertheless remain itself. What continues is not a fixed collection of material, but the constrained organization of relations among differentiated elements and that organization’s capacity to maintain coherence through change.

This does not mean that a concept really exists whenever it appears internally coherent. Fictional characters, mathematical possibilities, and living structures in the actual world can all possess some kind of formal coherence without sharing the same mode of existence. A claim about real existence must at least answer how the thing is distinguished from what it is not, what constrains it, through which relations it persists, at what scale it retains identity, and whether it leaves effects, continuities, or traces within real relations that distinguish its existence from nonexistence. Structural describability, logical consistency, real instantiation, and degree of empirical credibility must remain distinct.

This makes Sustenesis different both from substantial materialism and from an unbounded spiritualism. It does not presuppose one kind of material as the sole qualification for all existence, but neither does it confer real existence merely because an object can be imagined or named.

God Is Not a Necessary Premise of Sustenesis Theory

“God” is not a concept with a single fixed meaning. A personal creator, the first cause of deism, the necessary being of classical theism, Spinoza’s God or Nature, and God understood as being itself or ultimate reality are not the same philosophical claim. This essay cannot address all these definitions at once. Its main concern is the function of God as creator of the world, source of order, ultimate ground, and ontological guarantor.

The core framework of Sustenesis Theory does not require this premise to be introduced first. Difference does not conceptually require a subject that produces difference, and Constraint does not necessarily imply an external will that legislates constraints. Constraint may appear as relations internal to a structure, mutual limitations among different structures, boundary conditions at a given scale, or the regularities actually presented by the world. Sustained Coherence provides a conceptual framework for analysing how order forms and is maintained under constraint without presupposing that this order must first have been designed by a personal will.

The core definitions and basic derivations of Sustenesis Theory do not take “God exists” as a premise. Its analyses of structural formation, maintenance, change, and failure can still be stated and applied without introducing that claim. This is what the essay means by saying that Sustenesis “does not require God.” It means independence at the level of theoretical foundations, not a proof that God does not exist. To say that the theory can “stand” here means only that its core concepts can be defined and its basic reasoning can operate; it does not mean Sustenesis has thereby been proven true. Its core concepts do not themselves decide between theism and atheism. Whether a particular theistic world is compatible with Sustenesis depends on whether that concept of God conflicts with the scope of Difference, Constraint, and Sustained Coherence. An atheistic world requires no additional theological premise. Choosing among these interpretations of the world requires further argument, but does not determine whether the basic Sustenetic criteria of existence can be stated and applied.

Sustenesis also does not thereby answer “why is there something rather than nothing?” Nor does it prove that Difference and Constraint have an ultimate source. The question remains. But the fact that an ultimate source can still be asked about does not directly entail that the source must be God, much less that God should therefore be made an axiom that general ontology must accept before it can begin operating. Constitutive conditions and ultimate source belong to different levels.

Sustenesis Theory is therefore not a concealed atheism. It does not require God not to exist. It removes only the necessity of God as the theoretical guarantor of Sustenesis. If God exists, particular conceptions of God must still enter an analysis of difference, relation, constraint, and sustained coherence. If a theology defines God as an absolute entirely beyond all difference and constraint, its compatibility with Sustenesis requires separate discussion. A theory’s independence from God does not make it automatically compatible with every definition of God.

The Soul Is Neither an Added Entity nor Excluded in Advance

“Soul” likewise contains several levels. Without distinguishing them, affirmations and denials of the soul readily shift their meaning. At minimum, we must distinguish the complete personal sustenetic structure during bodily life; the organization of identity not exhausted by its present material composition; the strong sense of a soul able to continue across changes of body or carrier; and the religious soul that exists eternally and bears ultimate responsibility. These claims cannot substitute for one another. Within Sustenesis, “do human beings have souls?” is no longer primarily a binary question about whether another kind of entity exists inside the human body. It becomes two consecutive questions: what constitutes the soul as a complete personal sustenetic structure, and whether that structure can continue its sustenesis across the constraints of the body.

For Sustenesis Theory, the soul is the complete personal sustenetic structure through which a person integrates body, self, consciousness, memory, feeling, relationship, value, and temporal direction across time. It is not an independent entity residing within the body, nor another little self capable of leaving the body at any moment. This definition does not reduce the soul to a fictitious name. A person’s parts and processes form the person’s integral existence only when they are connected, constrain one another, and maintain the first-person direction of a life. This whole cannot simply be identified with any one organ, a psychological state at one moment, or a fixed collection of matter.

In this structural sense, Sustenesis is not silent about the soul. It recognizes the reality of the soul as a complete personal sustenetic structure. What remains open is the stronger question: after the present body’s capacity for self-repair and self-maintenance has irreversibly ended, can this structure retain real causal continuity, organizational coherence, capacities for self-maintenance and self-operation, embodiment or environmental embeddedness, and first-person continuity in another carrier or structure?

Sustenesis cannot exclude this possibility in advance merely because the soul is not a material substance in the ordinary sense. In Sustenesis, whether an existence can continue is determined not by the permanent identity of its constituent material, but by whether the organizational relations that constitute its identity can continue under new constraints. The replacement of matter throughout life shows that identity of fixed material is not a necessary condition of personal continuity. This establishes only that material identity and identity of the person can be distinguished. It does not show that transfer between carriers can preserve the same subject.

Yet non-exclusion in principle is far from proof of real existence. An affirmative claim about a post-mortem soul must at least explain how a new carrier or structure receives the original subject’s causal continuity, organizational coherence, continuous memory, emotional and value direction, reflexive integration, capacity for self-operation, embodiment or environmental embeddedness, and first-person continuity. On this basis it must distinguish the continuation of the same subject from the copying of a similar structure, informational remains, the memories of others, and social influence. Without these conditions, “the soul continues to exist” remains an incomplete claim.

Brain injury and changes in states of consciousness induced by anaesthesia show that the consciousness and personality activity presently known to us is closely related to the state of the body, especially the brain (Di Perri et al., 2014; Norup & Mortensen, 2015). Sustenesis has no reason to avoid these facts. They impose important empirical constraints on strong claims about the soul, but they cannot by themselves deductively establish that no identity structure could ever persist across carriers under any conditions. Degree of empirical credibility and a priori ontological exclusion are not the same.

Nor can the preservation of information be automatically equated with the continuation of a soul. A person’s writing, images, data, or digital replica may preserve a great deal of structure without thereby acquiring that person’s first-person continuity. A rigorous Sustenetic account of immortality must preserve causal continuity, organizational coherence, the capacity for self-maintenance, and first-person continuity together. Similarity is not identity, and replication is not continued existence in the ordinary sense.

The claim that “Sustenesis cannot deny the soul” must therefore be understood precisely. It does not say that every conception of the soul is valid or that life after death has been proven. The stricter formulation is that Sustenesis cannot exclude a priori the possibility that the same first-person subject may continue its sustenesis in another carrier or structure. It rejects fixed material substance as the sole criterion of existence and transforms the continued existence of the soul into a question about conditions of maintenance, continuity of identity, transfer between carriers, and real evidence.

The Two Conclusions Are Not Symmetrical

The position of God and the soul in this essay can easily be mistaken for a compromise agnosticism, as though Sustenesis merely declined to take a position on either. In fact, the logical direction of the two conclusions is different.

Object What Sustenesis can conclude What does not follow
God The core concepts and reasoning of Sustenesis do not require God’s existence as a premise. God does not exist, or every theological definition is compatible with Sustenesis.
Soul Sustenesis recognizes the reality of the complete personal sustenetic structure and does not derive the necessary nonexistence of a soul in the stronger sense from its own principles. The soul can exist apart from the body, continue after death, or has been proven immortal.

The following is only a shorthand for the argumentative relation, not a formal proof. Let T be the core framework of Sustenesis Theory, G the existence claim about a creator or ultimate ground as delimited in this essay, and S the claim that the same subject preserves causal continuity, organizational coherence, and first-person continuity after bodily death. The essay argues that T does not take G as a premise of its derivation and does not by itself entail either S or ¬S. Whether T is compatible with a particular G still has to be judged from the specific attributes assigned to that God. One further qualification is required: Sustenesis does affirm the soul as a complete personal sustenetic structure; S refers to the stronger claim that this structure continues after bodily death.

With respect to God, Sustenesis establishes the independence of its theoretical foundation. With respect to the soul in the stronger sense, it establishes ontological non-exclusion. The first says that a philosophical framework need not make a certain existence its ground. The second says that a certain existence cannot be ruled out in advance merely because it fails to satisfy a substantial-material criterion. To merge both into one attitude would erase what is structurally important in this conclusion.

Sustenesis therefore does not simply say “God and the soul are both possible.” It changes the form of each question. The question of God no longer begins with “who must design and guarantee order?” It asks how difference forms order under constraint, how this order continues, and whether an additional explanation in terms of an ultimate source is still needed. The question of the soul no longer begins with “is there an immaterial entity hidden inside the body?” It asks whether the sustenetic structure that carries first-person integration and continuity of identity can continue in another carrier or structure once the constraints of the original body fail, while preserving causal continuity, organizational coherence, capacity for self-operation, environmental embeddedness, and first-person continuity.

This does more than suspend judgment. It transforms two overly general existence questions into questions for which conditions, mechanisms, evidence, and refutations can be further specified.

What Dependence Does Sustenesis Actually Release?

It may be objected that Kant and many modern secular philosophies have long ceased to treat God and the soul as foundations of theoretical knowledge, and that Sustenesis therefore brings no new change. This reminder is necessary. Sustenesis should not claim to be the first to suspend judgment about God or reject a substantial soul. Aristotle, Kant, process philosophy, phenomenology, and many contemporary theories of mind have all repositioned these concepts in different ways.

The work of Sustenesis is also more than suspension. Within a positive ontological framework, it separates three levels that had constrained one another: the conditions under which existence in general forms; whether God exists and constitutes an ultimate ground; and whether the complete personal sustenetic structure can continue across the present body. Difference, Constraint, and Sustained Coherence allow the first level to be stated independently. The other two return to the definitions and arguments that each must separately bear.

This separation changes the relation among theism, atheism, and theories of the soul. Theism may further argue that God is the ultimate source of Difference and Constraint, but cannot make this claim a necessary axiom of Sustenesis merely because the theory still permits an ultimate question. Atheism and reductive physicalism are not necessarily bound together; rejection of the God hypothesis does not imply that every non-substantial holistic structure is fictitious. A theory of the soul can investigate personal structure and continuity across carriers, but cannot use the word “immaterial” to bypass questions of identity, causality, and evidence.

Religion and faith thereby receive a more precise position as well. Religion is a public and historical sustenetic structure. Faith is the subject’s sustained commitment through which an existence, value, or ultimate judgment is incorporated into the direction of life. Both can be compatible with Sustenesis and can become objects of Sustenetic analysis, but neither can replace the theory’s own derivation. Whether a person believes in God does not determine whether the core ontology of Sustenesis can operate. Whether a person believes in a soul after death cannot determine whether the complete personal sustenetic structure is real.

What this work releases is not the unknown, but foundational dependence. Sustenesis does not resolve every factual question about God and the soul. It releases its core ontology from prior dependence on those two claims and thereby shows that a general ontology need not begin from their prior adjudication. In Sustenesis, God is no longer posited as the theoretical premise that guarantees the world, but becomes an ultimate existence claim requiring independent discussion. The soul is no longer forced to be accepted or denied as a second substance, but becomes a question that must be studied in terms of structure, constraint, continuity, and evidence.

Conclusion

The placement of God and the soul is a longstanding structural tension within Western metaphysics and modern philosophy of mind. The importance of Sustenesis Theory does not lie in declaring these questions closed, nor in offering a compromise between theism and atheism. Its work is to rearrange the levels of the problem.

Sustenesis does not need God to exist in order to establish its core concepts and analysis. God is therefore no longer a necessary guarantor of its core ontology. But this does not mean that God does not exist; particular conceptions of God still require independent argument. Sustenesis understands the soul as the complete personal sustenetic structure and therefore does not accept the soul as a mysterious entity added to the body. At the same time, it does not allow the possibility that this structure might continue beyond the body to be denied a priori solely by a material-substance criterion. Any stronger claim about the soul must still confront causal continuity, organizational coherence, the capacities for self-maintenance and self-operation, embodiment or environmental embeddedness, first-person continuity, and empirical evidence.

Sustenesis therefore does not end discussion of God and the soul. What it releases within its own framework is prior dependence on these two claims. Sustenesis no longer needs to establish itself by affirming or denying God and the soul. Claims about God and the soul must instead be defined, analysed, and argued separately, then assessed and corrected in accordance with their own evidential conditions.

The most concise formulation is:

Sustenesis does not take God as a premise, nor does it establish itself at the cost of denying the soul. It removes God from the position of necessary guarantor for Sustenesis, and removes from a fixed material-substance criterion the right to reject the soul a priori.

This is not an evasion of two ancient questions. It is a structural reset of their relation to philosophy.
