Abstract

The philosophy of superdeterminism is based on a single scientific fact about the universe, namely that cause and effect in physics are not real. The philosophy of superdeterminism is supported by entropy in the light of principles of reductionism. The second law of thermodynamics and the universe's drive towards higher entropy create a clear arrow of time at the macroscopic level, which aligns with our subjective experience of time moving forward. As time moves forward, we observe causes disappearing and transforming into effects. But, at the most fundamental level described by time-reversible laws like Newton's Third Law, the universe does not inherently recognize a directed cause and effect in the way we intuitively grasp it. Time-reversible laws are considered more fundamental than entropy, because they describe the behavior of matter and energy at their most basic, often microscopic, levels and work equally well whether time flows forward or backward. If causes truly disappeared, a reversed process would imply something appearing from nothing, which would violate conservation laws that are central to these fundamental laws. Because our experience of cause and effect is an emergent phenomena based on entropy and not a fundamental principle of physical reality, then we should believe that the fundamental principles of physical reality pointing toward a static block universe is the truth. Moreover, because the most fundamental principles of physical reality do not recognize cause and effect, then we should disbelieve in cause and effect in physics in accordance with the principle of reductionism. A superdeterministic interpretation positing a predetermined static block universe without cause and effect in physics aligns well with a reductionism, because it takes the time-symmetric nature of fundamental laws at face value. Because fundamental laws do not have a preferred direction of time, then a model where all moments in time exist equally is a more direct consequence of these fundamental principles than a model with a flowing time and inherent causality.
