The Heisenberg Uncertainty Principle as a Refutation of Causality

Many commentators on Heisenberg’s Uncertainty Principle claim that, because we cannot at the same time specify fully the position and momentum of subatomic particles, their action is not entirely predictable, and that the law of causality therefore breaks down. This is a non sequitur, a switch from epistemology to metaphysics, or from knowledge to reality. Even if it were true that owing to a lack of information we could never exactly predict a subatomic event–and this is highly debatable–it would not show that, in reality, the event was causeless. The law of causality is an abstract principle; it does not by itself enable us to predict specific occurrences; it does not provide us with a knowledge of particular causes or measurements. Our ignorance of certain measurements, however, does not affect their reality or the consequent operation of nature.1
