Abstract

Between Physics and Metaphysics — on Determinism, Arrow of Time and Causality

Highlights

  • From times of Aristotle, physics is called as a starting subject in philosophical discussion: the teleological cause appeared in his Physics

  • Albert Einstein first, just at the dawn of the 20th century, still within the classical physics and Werner Heisenberg soon later, within the quantum mechanics, expressed doubts on the possibility of the exact description; a simplified conclusion is sometimes drawn that the physical world is not deterministic, ontologically

  • Heisenberg, in particular in discussion with Einstein, sustained that the quantum mechanics removed the determinism from physics: we cannot predict the path of an electron

Summary

Introduction

The question to which extent we determine our lives and how it is decided by some external fate waving our live thread, is probably as old as the human reflection. Section One. Inert Matter of physics in the contemporary philosophy is that it brought two spectacular mental revolutions: quantum physics and Einstein’s relativity. Inert Matter of physics in the contemporary philosophy is that it brought two spectacular mental revolutions: quantum physics and Einstein’s relativity Both of them are still far from being understood. From times of Heisenberg “the future is no longer contained in the past” says British physicist (and theologian), John Polginghorne (1989) Both revolutions of modern physics are commonly considered as ontological, suggesting that the micro-world is chaotic-like and the macro-world is relative. We conclude that the ontological determinism holds firmly in physics, but the epistemic indeterminism, for several reasons, is a limiting feature both in classical and in quantum physics
