Are Gradients Sufficient for Life?

This paper argues that gradients constitute the primordial ontological condition for the emergence of life, providing the first structure capable of sustaining interiority, agency, and temporal identity. While biology universally acknowledges gradients as necessary for metabolism, signaling, and far‑from‑equilibrium organization, they are typically treated as tools employed by already‑living systems. I challenge this assumption by proposing that gradients themselves embody the earliest form of proto‑agency: a directed organization of energy that persists, propagates, and responds to perturbations. When stabilized or enclosed, gradients generate organized interiority—the first boundary separating inside from outside and enabling a system to evaluate its own conditions of persistence. From this perspective, gradients are not merely enabling conditions but the ontological seed from which life becomes possible. Although empirical work has not yet demonstrated a full transition from gradient‑driven organization to autonomous living systems, existing evidence shows that gradients can drive chemical complexity and self‑organization. I conclude that gradients are sufficient at the ontological level for life’s emergence, forming the foundational architecture from which interiority, agency, and meaning arise.
