Does quantum mechanics disprove the Principle of Sufficient Reason?
Lets say a scientist were to perform the double slit experiment. He sends in one electron through the slits and then that he measures the random location on his measurement device after the wavefunction collapses. Now if one were to ask what was the…

How do Thomists prove that: "Everything that exists must exist by something."?
One variation of principle of sufficient reason that Thomists use is:
Everything that exists must exist by something.
How do they prove such a statement? In particular, why can not something just exist (de facto) and not by anything else?
Edit.
I…

Everything must have a cause?
In a possible reality, if something came into existence without something giving rise to it, the fact would be that , there was nothing stopping something from coming into existence without anything giving rise to it, and if this was the existing…

Does the Principle of Sufficient Reason imply everything is necessary?
Leibniz's Principle of Sufficient Reason (PSR) states that: for every fact F, there must be a sufficient reason why F is the case (https://plato.stanford.edu/entries/sufficient-reason/#WhatSuffReas). This applies to all contingent facts.
For…

On the axiomatic behavior of the principle of sufficient reason
Have a look at the most controversial principle popularized as the principle of sufficient reason (PSR):
I mean that the concept of PSR, which has been introduced by Gottfried Wilhelm Leibniz, remains as an axiom. Otherwise, including the question I…

Relationship between Causal Determinism and Principle of Sufficient Reason?
Causal Determinism is the concept that events are bounded by causality in such a way that any state (of an object or event) is completely determined by prior states.
The Principle of Sufficient Reason states that everything must have a cause or…

Relationship between Principle of sufficient reason and Law of identity
I have an intuition that one can derive the principle of sufficient reason from the law of identity or non-contradiction but i don't know how.
If someone knows I'd like some help.

They in their 1999 article said if it be possibly that there be a God who freely created the world using S5 modal system there be such…

A quantum mechanical response to van Inwagen's rejection of the PSR
Peter van Inwagen famously rejected the PSR due to his argument that it implied necessitarianism: Take the conjunct C of all contingent facts. Being contingent itself, the PSR demands an explanation F. F must be necessary. But if F is necessary and…
