How do Thomists prove that: "Everything that exists must exist by something."?

Thomists affirm theism, but God would be a counterexample to your proposition as stated: God is something "that exists" in Himself; He does not "exist by something [else]". ...

Does the PSR violate Occam’s razor?

No. To consider them at odds would be the product of committing a category mistake. The Principle for Sufficient Reason is an observation about how causality and explanation are universally applicable ...

How do Thomists prove that: "Everything that exists must exist by something."?

There isn't really a ubiquitous reading of the principle of sufficient reason (PSR), so I think it's worth going over some distinctions and different formulations. There are at least two major ...

Does quantum mechanics disprove the Principle of Sufficient Reason?

The philosopher Robert Nozick said it does. Only a weakened form of the PSR can survive. Paraphrasing: if there is no reason for something, then there is at least a reason for there being no reason ...

On the axiomatic behavior of the principle of sufficient reason

On the axiomatic behavior of the principle of sufficient reason It looks like your question asks for some proof that PSR is not simply an axiom, but is provably true. If my assumption is incorrect, ...

Can the PSR be true for everything except the universe?

It is inconsequent to announce “Everything happens for a reason”, and immediately to exempt from this universal principle the universe as a whole. Also your argument from induction is not conclusive. ...

Does the PSR violate Occam’s razor?

You've not been paying attention to the answers to your earlier question about Occam's razor, which should have made it clear to you that an argument with fewer assumptions need not be better if the ...

What is the reason for a god to create the world?

The phrase The god created the world to show his glory. which circulates the Internet, from Isaiah 43:7, to my understanding is taken out of context, is poorly translated and does not describe well ...

What is the reason for a god to create the world?

I've heard the above (ego motive), as well as something like "it pleased God" (hedonic motive), or "God saw that the [X] was good" (moral/ethical motive, from Genesis) so perhaps ...

Does the PSR violate Occam’s razor?

OP: Contrary to the widespread intuition that by default everything has an explanation, it seems instead that one should assume there is no explanation for X since that is by default more parsimonious....

Does quantum mechanics disprove the Principle of Sufficient Reason?

Arguably not, if you allow chance to be a cause, which Aristotle noted in his Metaphysics, that some philosophers argued for. This thread of thought has been forgotten since the success of Newtonian ...

On the axiomatic behavior of the principle of sufficient reason

The principle of sufficient reason is really just the principle that humans believe something if they have sufficient reason to believe it. We will only stop believing it if we find a sufficient ...

Everything must have a cause?

This question pops up a lot. Philosophers have been pointing out for centuries that this breaks down when we try to extend it beyond tangible objects in our universe. For example, the existence of ...

Everything must have a cause?

A partial answer / framing challenge. It may be more helpful to think of necessary antecedent states than causes. Empirically, we can't actually measure causation X -> Y, we can just measure that ...

Everything must have a cause?

The question "Must everything have a cause?" is a metaphysical question. Therefore, no appeal to the body of physics directly can solve the question, because the question is one of ...

Everything must have a cause?

We do sometimes speak of negative causation, where an absence is interpreted as functionally covariant with an event (i.e. the null input into some causal function yet has a nonzero output). So we ...

Hmmm. There are better answers than self-glorification. One of the better monotheist answers I have seen is to create beauty thru infinite diversity. Another better monotheist answer from open theism ...

Does the PSR violate Occam’s razor?

Occam's razor is consistent with the PSR, because in general, a world in which there are reasons for things is a simpler world. If it is necessary to describe a world containing A and B, a description ...
