That is true. If you want to learn what someone else has invented, you have to accept what they say long enough to see how, when, and if it fits your concerns. You cannot prejudge.
Most commonly based on what has already been accepted, but not always.
It makes sense to the philosopher who is attempting to see if even the most fundamental presumptions concerning existence are valid. But that is not you. You are, apparently, wanting to learn of what specific others have put together, which is fine by me. What you don’t seem to realize is that ALL of those “others” started off with nothing more than “metaphysical hypotheses”.
Until you know for certain what all of the rules are, how do you really know that the rules are different? The “rules” are merely the principles built upon an understanding. Different understandings (different ontologies) produce different rules and they can all be correct even though very different.
I started, not by assuming a bunch of rules, but rather by choosing a definition of what it means to exist - the very fundamental level of concern. But having done that, with a little math, I can already deduce many things that have no option but to exist regardless of what anyone has ever said or thought they saw.
Start at the very bottom of the complexity where you can know something with absolute certainty and then work your way up to where everyone else has been making assumptions and see how much fits together;
I was surprised to discover exactly how and why sub-atomic particles form. There isn’t any question to be had about it. And I didn’t have to use a single microscope or know anything at all about any physics. And that is because I started with what is necessarily true, primarily: “To exist means to have affect” and that “absolute zero difference in affect cannot ever happen”. From there, it is merely graphing the consequences. The entire universe of physics comes to light… not a single microscope was required… except to verify that what I deduced was also what they see.
That is the “top down approach”: “I can see this, so let me see a little closer/deeper”. That is how it has been done. But they have already discovered problems with that approach even though it helped a lot at first. They eventually find that nothing they have been “seeing” really is what they thought and some of their thoughts simply don’t work out. They find paradoxes, because they didn’t start with what is necessarily true, but rather what they saw. Observations are tricky. That is what magicians teach you.
Seeing might be believing, but believing isn’t knowing.
It is very easy on the internet to sense an offense when there really wasn’t one there. It is easy to presume that anyone you are talking to doesn’t know much more than you. It is common for people to say, “no one knows…”. People think in terms of this single data base of all human knowledge that everyone has access to. But think about that. Who could ever really claim that no one knows about something? What you see and hear about isn’t even 1/1000th of what is known by others. And Wiki is not told of very many things. But it is true that usually, you don’t meet anyone on the internet who knows much more than yourself. So it is tempting to get defensive about what you already believed to be true.
On that other thread, I proposed a situation for Relativity to explain. But Relativity can’t explain it. And in fact, Relativity can’t even predict an answer for it. It is a paradox for Relativity. But I can explain the truth of it and predict the exact answer, but trying to use Relativity. When you understand things from the ground up (rather than from what you see, down), there are no paradoxes.
