Well, I think it gets to the question of what the verb 'exists' actually means. For example, we can agree that certain fictional characters do not exist (Santa Claus, Sherlock Holmes, an honest politician). But *why* do they not exist? What is it that separates them from those things that do exist?
I don't really have a fully formed theory about what the word 'exists' means. But I guess that as an initial approximation I'm inclined to think of something that exists as having its own mind-independent reality. Fictional characters are obviously a problem-case. I guess that I'd say that Sherlock Holmes wouldn't exist if there were no minds capable of understanding Conan Doyle's stories. All there would be is squiggles of ink on pieces of paper.
Ultimately, it is because we can detect things that exist and not things that do not exist.
I don't want to embrace what appears to me to be the idealistic premise implicit there. The way I see it the mind-independent reality of certain things (those that exist) is in no way dependent on what we can or can't detect.
What might arguably be dependent on what we can and can't detect is our knowledge of those things. I'm a bit leery of that idea since we can seemingly know of things by inference, as well as by direct detection. But that might still arguably depend on the detections from which we draw our inferences.
Sorry, but Aristotelian philosophy and metaphysics needs to be left in the last millenium. There are just too many basic philosophical mistakes there to make the system useful.
I have the greatest respect for and interest in Aristotle. He was probably the greatest thinker in all of human history, judging from his surviving works. But that doesn't mean that I accept all of his views. Aristotle was basically inventing many of his subjects de novo for the first time. He was the first logician, the first scientific biologist and many more. Many of the departments in our universities address subjects that Aristotle first defined. Others followed after and expanded on the intellectual subjects he pioneered, but that doesn't detract from his creativity and vision in initially inventing the subjects. But that's neither here nor there, since nothing I wrote is dependent on Aristotelian philosophy.
No, I do not agree with the 'Principle of Sufficient Reason'. I don't believe that everything that exists has a cause.
The Principle of Sufficient Reason didn't originate with Aristotle. Earlier philosophers like Anaximander and Plato knew it. It didn't culminate with Aristotle either. History's biggest proponent of the Principle of Sufficient Reason was probably Leibniz.
I'm undecided on it and certainly am not wedded to it. I was just pointing out how it can be used in an argument for a Deist-style 'God', even if we have no direct or indirect way to detect such a deity.
Contra the Principle of Sufficient Reason I'm willing to entertain the possibility that entirely anomic states of affairs might sometimes exist, states of affairs inexplicable by and perhaps even inconsistent with plugging earlier physical states into the "laws of physics". But I'm not convinced that random stray states like that actually occur, I just don't want to close off the possibility by fiat.
The Principle of Sufficient Reason does seem to be implicit in the practice of science today. We don't just accept biological species as givens, instead like Darwin we want to know how species originate. If we detect a big flash of light a few miles away, followed by a loud concussion, we want to know what exploded and why. If we see a bird soar overhead, we don't just conclude that it's part of the essence of birds to fly. We want to know about the aerodynamics of how birds do it.
Perhaps it's inherent in human cognition. I'm not sure that my dog thinks in terms of explaining things. Whatever she encounters is simply how things are.
I don't think it even works that far. For example, God exists (according to this logic), but has no sufficient reason to exist (a thing cannot be the sufficient reason for its own existence). So that is a contradiction to the system.
It does seem to lead to infinite regresses. We can ask 'why' repeatedly. Every time we get an answer (our sufficient reason) we can ask 'why' about that reason. That's not a contradiction though, strictly speaking. Though how some theists use the principle to terminate in God certainly seems to be. I agree with you about that.
But isn't it also a contradiction to combine "a thing cannot be the sufficient reason for its own existence" with an attack on use of the principle of sufficient reason to hypothesize an explanation other than itself? The path between that Scylla and Charybdis looks to be exceedingly narrow. There might arguably be problems either way.
Ultimately, metaphysics tends to be a collection of biases that people claim are 'obvious'
The same could be said about mathematics which seems to ultimately be based on intellectual intuition. I can't explain the seeming objectivity of mathematics, but in some of my moods I tend towards mathematical Platonism, which obviously is a metaphysical position.
I personally think that the metaphysical questions are the deepest and most fundamental questions we can ask about pretty much anything. I'm not convinced that human beings will ever be in a position to answer those questions. But until we can, the rest of our vaunted understanding will seemingly float without foundations.
And I don't think that we will ever make much progress in the philosophy of religion if we are unwilling to consider the metaphysical issues.
when, in fact, they are usually just false.
How does one determine truth and falsity in matters like these?
