Unified Field Theory: Different Principle or Too General?

[putongren]

If Classical Physics (Newton, Maxwell, Einstein) operates on the principle of determinism and causality, Quantum Mechanics operates on the principle of probability, then would the Unified Field Theory (or Theory of Everything) operate on a yet different principle? Or am I being too general?

We can't know until the theory is finally discovered but more than likely whatever we do discover will just lead to new deeper theories.
