Abstract

Determinism is a philosophical position which states that all events in the universe are predetermined by already existing causes. Since Sir Isaac newton developed his causal (cause and effect) classical mechanics, this theory about the nature of the universe was the predominant theory in science and more specifically in physics. However, following the development of the probability-based quantum mechanics in the early 19th century, there was now strong reason to doubt the validity of determinism.

The purpose of this investigation is, therefore, to determine whether determinism is compatible with quantum mechanics. The first section of this investigation will analyze four phenomena in quantum mechanics, namely the double slit experiment, the Compton Effect, the Heisenberg Uncertainty Principle, and Quantum Tunneling, and present which problems each of the quantum mechanical phenomena pose for determinism. The second section will then be focused on replies from philosophers concerned with determinism to these problems posed from quantum mechanics. Lastly the third section will focus on considering quantum mechanics in the context of science in general, and whether this yields any evidence on the compatibility of the two subjects. Ultimately, it was concluded that that quantum mechanics and determinism can only be meaningfully compatible through either an emergence of new technologies, a restructuring of the way we do science, or a reframing of what we consider the deterministic system in the universe.
