Do we have free will?
OPH proposes a reconciliation of fate and freedom. A complete history contains your deliberation and decisions as events that help determine what follows. Think of a Sudoku whose clues admit one completed grid: its entries must fit together, yet the deductions that fill it are genuine work. In the universe analogy, we belong to the solution and perform the deciding within it. Freedom means being able to consider alternatives, respond to reasons and act through your own organization. It does not mean acting outside every constraint. Fate names the history taken whole, including those acts. There is no external clock on which everything happened earlier, and the finite agreement theorem does not prove that only one universe is possible. This is a compatibilist account: it makes choices consequential without claiming an uncaused will.

This answer comes from OPH, Observer Patch Holography. OPH is a rigorous, consistent and complete description of the unified, self-creating computational Universe we inhabit. Its consistency is machine-checked: the fixed point at its core is constructed explicitly, and a theory with a model contains no contradiction.
To understand OPH and check every step yourself, start with the free book Reverse Engineering Reality. It builds the theory from the ground up, and the OPH Notebook answers your questions while you read.
