Constructor Theory

What this approach tries to solve

Constructor theory seeks to express fundamental theories in terms of which physical transformations are possible or impossible, rather than only predicting what happens from initial conditions and equations of motion. Deutsch frames that possible/impossible transformation distinction as a proposed mode for fundamental theories. See Constructor Theory.

What Panta Rhei shares

Panta Rhei shares interest in possibility and impossibility, modal structure, constraint, and construction rather than prediction-only explanation.

It also shares the conviction that physical law should not be reduced to trajectory calculation alone.

Where Panta Rhei differs

Constructor theory begins from tasks and transformations.

Panta Rhei begins from the prior burden: what must be constructed for task, transformation, possibility, impossibility, law, and constructor to be meaningful inside a coherent theory of reality?

Panta Rhei’s Construction Spine is not only a modal theory of tasks. It is a build sequence from kernel to mathematics, physical carrier, life, reflection, self-hosting, and ontic-closure testing.

Constructor theory asks which transformations are possible. Panta Rhei first asks what semantics make transformation, possibility, law, and constructor admissible inside a theory of reality.
