Despite majority of theoretical physicists begin to accept the post-empiricism doctrine, still few physicists and mathematicians alike don’t agree with such a doctrine, partly because it is against Popper’s criterion of falsifiability for any theory in physics and other sciences. And partly because criteria like beauty or elegance seem rather subjective for a theory to be accepted as “physics’. Physicists like Peter Woit and Sabine Hossenfelder have written books on this topics [10-11]. In this article, we don’t repeat those arguments, instead we only argue in favor of principle of parsimony, or that Nature seems to prefer least action, or least energy either in modeling complexity, assumptions and free parameters involved, and minimizing computational entropy required before getting any meaningful results. Therefore, we arrive at conclusion that one shall find a balance among some criteria, of which we may call this point “Ockham optimality point..” We hope that this article points out to new hints to the problems of theoretical physics, as Woit and Hossenfelder lamented.
