Does QM end Free Will/ Determinism debate ?

Click For Summary

Discussion Overview

The discussion revolves around the implications of quantum mechanics (QM) on the concepts of free will and determinism. Participants explore various interpretations of QM, including deterministic and indeterministic views, and their potential impact on causality at the subatomic level.

Discussion Character

  • Debate/contested
  • Philosophical exploration

Main Points Raised

  • Some participants question whether deterministic interpretations of QM can coexist with the concept of free will.
  • Others inquire if indeterministic interpretations of QM provide evidence against causality at the subatomic level.
  • One participant expresses confusion about the definitions and implications of free will, determinism, compatibilism, and libertarianism.
  • A participant suggests that quantum effects become probabilistic at the macro scale, implying that the universe is not purely random.
  • Another participant emphasizes that the debate on free will is ongoing and that eliminating one interpretation may not resolve the philosophical questions surrounding it.

Areas of Agreement / Disagreement

Participants do not reach a consensus; multiple competing views on the relationship between QM, free will, and determinism remain present in the discussion.

Contextual Notes

There are limitations in the discussion regarding the definitions of free will and causality, as well as the philosophical implications of different interpretations of QM, which remain unresolved.

Hello :smile:

I think my question is clear...
Another questions that need to be asked:
  • What about the deterministic interpretations of QM?
    and
  • Do indeterministic interpretations PROVE that there is really no causality on subatomic level ?
Please help me! I am more than a little confused about the meaning of this concepts. :confused:

Thanks :-p

Quantum physics does not make the universe purely random as quantum effects become probabilistic on the macro scale (thus is my understanding).

As for the determinism/free will debate I rarely hear anyone adequately explain what they mean by "free will". The three schools I thought I've learned of are determinism, compatabilism and libertarianism (not to be confused with the political/economic philosophy). The first of these states that all actions are pre-determined so free-will does not exist, the latter claims that something unique about conscious decision making means that cause and effect do not apply to it (a religious claim if there ever was one). The middle philosophy which I subscribe to highlights that even though some actions may be inevitable (or probable) we still have experience and knowledge of decision making and so they are useful terms that we can utilise.

Welcome to PhysicsForums, Van Dort!

The debate is far from over, for a variety of reasons. First, there are viable determininstic and indeterministic interpretations currently on the table. Second, I doubt that eliminating one or the other will fully settle anything. There is a lot of room for philosophical discussion of what free will is anyway. Ditto for causality.
