Has quantum mechanics destroyed the fundaments of logical reasoning?

The idea that quantum mechanics fundamentally challenges the rules of logic was popular for a while, but has fallen out of favor in recent years. While intuitively it might seem that quantum ...

What is unique about the quantum state of superposition?

I recently answered a similar question on physics.SE here. What is special about the probabilities of quantum mechanics is that the randomness cannot be explained by a theory of nature that is both ...

"God doesn't play with dice": does QM's randomness really contradict religion?

Chance is the pseudonym of God when he did not want to sign. - Théophile Gautier came to my mind. It is a view that you can sometimes encounter in the Catholic Thinking. Quantum randomness would ...

Has quantum mechanics destroyed the fundaments of logical reasoning?

Let me clarify a confusion first. Logic applies to sentences, not to objects, so object's ability to be in two places at once is not a contradiction, unless definition of "object" rules out such a ...

How does Quantum Mechanics affect the modern account of free will and determinism?

The OP quote draws a distinction between determinism ("hard determinism"), and causal completeness ("less absolute determinism"). The former means that the current physical state ...

Philosophical implications of entangled states (and the 2022 physics nobel prize)

What are the arguments for or against the wavefunction being a subjective vs an objective entity?

In practice the wave function is a mathematical model which we can use to calculate certain properties of systems, subject to a variety of approximations. What the wave function is modelling (ie what ...

How does Quantum Mechanics affect the modern account of free will and determinism?

First a point of clarification, from what you are describing, you are talking about libertarian freewill, not compatibilist freewill. More on that later. At the heart of your question is a confusion ...

"God doesn't play with dice": does QM's randomness really contradict religion?

Einstein was a proponent of hidden-variable theory. The gist is that, if something appears random, then it's really just chaotically dependent upon information we don't have. So, God (the universe) ...

Does ones interpretation of quantum mechanics alter one's moral philosophy?

Your question relies too much on there being only two worlds - one where the 1% event happened, and one where it didn't. I think the more reasonable many-worlds interpretation is that out of the ...

How can we take the ontologies of our best physical theories seriously?

What is the most commonsense interpretation of QM for the layman?

This question presumes not only the existence of common sense, but that two individual's common sense about a very peculiar topic might somehow coincide. As Einstein categorized it, there were four ...

Has quantum mechanics destroyed the fundaments of logical reasoning?

Logic is an abstract concept which does not necessarily directly tie to reality. We like to argue that there is at least a very solid indirect relationship, in that logic does a good job of ...

What is unique about the quantum state of superposition?

The key characteristic of a quantum superposition is that all superposed states are equally real (or potentially real) at the physical level. This is quite different from a classical probability, ...
