Antecedence Criterion

Definition

The antecedence criterion is Grant's requirement that a ground be prior to what it grounds without being exhaustively recoverable from the grounded result. The criterion blocks a common equivocation: rejecting substance as ground does not abolish the priority of generative conditions over the actual things they generate (Iain Hamilton Grant/Texts/Essays/Does Nature Stay What-it-is Dynamics and the Antecendence Criterion.pdf, pp. 3–4).

Grant introduces the criterion within a dispute over logical, real and material grounds. Logical reason may fail to exhaust real ground, while materiality may exceed actuality by including powers and possibilities not realized in any present state (Iain Hamilton Grant/Texts/Essays/Does Nature Stay What-it-is Dynamics and the Antecendence Criterion.pdf, pp. 1–3). Matter is therefore not an inert substrate underneath beings. In a dynamical account it is a field of powers whose operations precede the products through which those powers become legible.

Against logical regionalization

Grant's targets are accounts that relocate dynamics from nature into activity or logical space. Fichte makes activity the source of reason while denying nature self-change; Gunnar Hindrichs makes grounding an operation internal to an atemporal order of reasons (Iain Hamilton Grant/Texts/Essays/Does Nature Stay What-it-is Dynamics and the Antecendence Criterion.pdf, pp. 6–9, 17). Both satisfy a formal demand by cutting it away from causal nature.

The criterion rejoins the two. A reason is supplied after an event, but reason-giving is itself an event in the same nature. Grant reads Leibniz's principle of sufficient reason as binding reasons to causes through a sequence of antecedents and consequents, rather than as an escape from physics into a timeless logical order (Iain Hamilton Grant/Texts/Essays/Does Nature Stay What-it-is Dynamics and the Antecendence Criterion.pdf, pp. 14–16).

The mountain example

Grant's mountain makes the asymmetry concrete. Thinking a mountain requires both that there already be a mountain to think and that the causes of mountain formation participate in the later capacity to think it. Reflection cannot recover this sequence completely because each thought about a prior thought is another later event, while geological causes branch into speciation, meteorology and other processes not reducible to the mountain as an isolated object (Iain Hamilton Grant/Texts/Essays/Does Nature Stay What-it-is Dynamics and the Antecendence Criterion.pdf, p. 17).

Being is antecedent to thinking in this strict genetic sense. The claim does not deny that thought is real or causally effective; it denies that thought can retrospectively install itself as the condition of the processes that produced it. Reverse inquiry finds no ultimate substantial ground, but forward operation finds powers, potentiae and productivity (Iain Hamilton Grant/Texts/Essays/Does Nature Stay What-it-is Dynamics and the Antecendence Criterion.pdf, pp. 17–18).

Consequence remakes antecedence

Antecedence does not imply that the past fully programs the future. In naturephilosophical futurism, Grant argues that a consequence determines its antecedent as the antecedent of this consequence rather than another. Futures redirect what their pasts would otherwise have done and thereby multiply beginnings (Iain Hamilton Grant/Texts/Essays/Nature After Nature, or Naturephilosophical Futurism.pdf, pp. 6–10, 14–15). The prior remains efficacious, but its identity as a prior is locally revised by what follows.

This is why antecedence belongs with deep field logic. Upstream conditions are real and indispensable, yet any exhibition of them occurs downstream and adds a new event to the field. The criterion prevents the exhibition from being mistaken for the source (Iain Hamilton Grant/Texts/Essays/Does Nature Stay What-it-is Dynamics and the Antecendence Criterion.pdf, pp. 17–18).
