E, so principles are healthful when we want to conjecture fucial laws of physics. But you can need these other additional set of statements to fully explain them. The full theory of the world would clude both these general principles and some specific a adendum that says theyre, they're instantiated in the following way in the actual world. Is that correct? Or did i go too far? Yes, i think this is correct.

Traditional physics works within the “Laplacian paradigm”: you give me the state of the universe (or some closed system), some equations of motion, then I use those equations to evolve the system through time. Constructor theory proposes an alternative paradigm: to think of physical systems in terms of counterfactuals — the set of rules governing what can and cannot happen. Originally proposed by David Deutsch, constructor theory has been developed by today’s guest, Chiara Marletto, and others. It might shed new light on quantum gravity and fundamental physics, as well as having applications to higher-level processes of thermodynamics and biology.
