&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Ontological dependence&amp;#039;&amp;#039;&amp;#039; is the relation that holds when one entity, property, or fact cannot exist, obtain, or be what it is without another. A statue depends on the clay that constitutes it; a shadow depends on the object that casts it; a mental state depends on the neural activity that realizes it. The concept is central to [[Metaphysics]] because it provides the structural vocabulary for asking which aspects of reality are fundamental and which are derivative — a question that cuts across philosophy of mind, physics, biology, and [[Systems|systems theory]].&lt;br /&gt;
&lt;br /&gt;
The history of ontological dependence stretches from [[Aristotle]]&amp;#039;s distinction between substance and accident — where substances exist independently and accidents exist only in virtue of substances — through medieval [[Scholasticism|scholastic]] debates about creation and causation, to contemporary analytic metaphysics, where the relation has been formalized using tools from [[Modal Logic|modal logic]] and [[Model Theory|model theory]]. At every stage, the underlying question is the same: what is the architecture of reality? Which things stand on their own, and which things stand on the shoulders of others?&lt;br /&gt;
&lt;br /&gt;
== Varieties of Dependence ==&lt;br /&gt;
&lt;br /&gt;
Contemporary metaphysics recognizes several distinct species of ontological dependence, each capturing a different aspect of the &amp;#039;in virtue of&amp;#039; relation.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Modal dependence&amp;#039;&amp;#039;&amp;#039; is the weakest form: A depends on B if A cannot exist unless B exists. Formally, in every possible world where A exists, B also exists. This captures the intuition that the statue cannot exist without the clay, but it does not capture the stronger intuition that the statue is &amp;#039;made of&amp;#039; or &amp;#039;constituted by&amp;#039; the clay — only that the statue cannot survive the clay&amp;#039;s annihilation.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Essential dependence&amp;#039;&amp;#039;&amp;#039; (or &amp;#039;essentialist&amp;#039; dependence) is stronger: A depends on B if B is part of what makes A the thing it is. The statue does not merely require some clay; it requires &amp;#039;&amp;#039;this&amp;#039;&amp;#039; clay, or at least clay of a certain sort, as a matter of essential necessity. This form of dependence is tied to debates about [[Essentialism|modal essentialism]] and the question whether objects have individual essences that specify not just what they are made of but what they could have been made of while remaining the same thing.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Grounding-theoretic dependence&amp;#039;&amp;#039;&amp;#039; is the most discussed contemporary variant. Where modal dependence is an abstract pattern across possible worlds, grounding is a concrete, explanatory relation: A depends on B when A is grounded in B — when A obtains in virtue of B, and this &amp;#039;in virtue of&amp;#039; is not merely a modal correlation but a metaphysical explanation. The literature on [[Grounding|grounding]] has revived ontological dependence as a tool for framing debates about consciousness, composition, and the status of mathematical objects.&lt;br /&gt;
&lt;br /&gt;
== Dependence and Systems ==&lt;br /&gt;
&lt;br /&gt;
The systems-theoretic perspective on ontological dependence reverses a common philosophical assumption. Traditionally, dependence has been treated as a vertical relation: the lower level is fundamental, the higher level is derivative. But [[Systems|systems theory]] suggests that dependence is often mutual or circular. The heart depends on the liver for oxygenated blood; the liver depends on the heart for circulation. Neither is more fundamental — they are co-dependent components of an organization that is itself more fundamental than either part considered in isolation.&lt;br /&gt;
&lt;br /&gt;
This raises a challenge to the hierarchical model of [[Fundamentality|fundamentality]] that dominates analytic metaphysics. If dependence relations form networks rather than trees, then the search for a single &amp;#039;bottom&amp;#039; level may be misguided. [[Emergence|Emergent]] properties depend on their base properties, but the base properties may themselves depend on the emergent organization for their functional role. A neuron in a brain depends on the network for its informational significance; the network depends on the neurons for its physical realization. The relation is not unidirectional. It is a loop.&lt;br /&gt;
&lt;br /&gt;
The same structure appears in social ontology. A currency depends on collective acceptance for its value; but collective acceptance depends on institutional structures — banks, governments, legal systems — that are themselves constituted by further layers of social fact. The philosopher who treats one of these levels as &amp;#039;the fundamental one&amp;#039; is not discovering the architecture of reality. They are choosing a projection plane.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;The assumption that ontological dependence must terminate in a foundational level — a bedrock of independent existents — is not a theorem of metaphysics. It is a methodological habit inherited from theological cosmology, where God was the independent being and creation was the dependent one. In a naturalistic framework, there is no reason to expect dependence to bottom out. It may be dependence all the way down — a network of relations without a root node, an ontology of reciprocal constitution rather than hierarchical derivation. The task of metaphysics is not to find the bottom. It is to map the graph.&amp;#039;&amp;#039;&lt;br /&gt;
