Causal Time as a Real Feature of the Universe, Not a Psychological Artifact
DNA remembers every second it took to arrive.
Jim Rutt argues that causal time — the real, irreversible sequence in which things come into existence — is not a psychological illusion but an objective feature of reality, and that emergence itself proves the block universe wrong because complex things like DNA are literally records of elapsed causal history.

Jim Rutt has proposed elevating causal time to the status of a foundational axiom within his minimum viable metaphysics — a framework that seeks the smallest set of commitments necessary to do serious ontological work. This move directly challenges the block universe interpretation that has dominated theoretical physics since Minkowski and Einstein, in which all moments exist tenselessly and the experience of temporal flow is epiphenomenal. Rutt's counter-argument is grounded in Emergence: the causal sequence that produces stellar nucleosynthesis before heavy elements, and heavy elements before biological complexity, is not merely descriptive but constitutive. These entities are defined by their causal ancestry.
The argument gains particular force through reference to Assembly Theory, developed by Sara Walker and Lee Cronin. Their framework quantifies the minimum number of joining operations required to construct a given molecule, effectively encoding how much causal history that molecule presupposes. A molecule with high assembly index — DNA being a paradigmatic example — implies billions of years of prior physical and chemical processes. It cannot be adequately described in a framework where all times are ontologically co-present, because its very identity is inseparable from the sequential process that produced it.
This perspective reframes the arrow of time from an explanatory problem to an explanatory resource. Rather than treating temporal asymmetry as a puzzle to be dissolved by fundamental physics, Rutt treats it as an objective structural feature of reality — one without which Emergence, complexity, and ultimately anything worth explaining would be impossible. The arrow of time is not a residual illusion awaiting reduction; it is the precondition for ontological novelty.
