rjbuffchix: Reality, reality alone, determines what is true.
Not to derail too much but I can only partially agree with this. It still, kinda, grinds my gears. I try to explain. The rest of your comment is common sense. However, if someone feels fear then the person still felt fear so with that in mind isn't that also "reality", even if its caused by circumstances that aren't grounded in reality as we both understand it?
Anyways, its simple to understand but reality, more than often, is far more complicated than this simple saying. There is a reason its really easy and compelling to believe stuff like flat earth is the truth simply because the real truth requires more intricate knowledge and even then the statement "The Earth is round" is not really "objective truth" at all. It all boils down to making proper explainations by using and comparing axioms but I'm sure you know about this stuff already.
Anyway, back when I was much younger I actually thought about what might account as "real truth".
Do you know what a frostum is? If truth would be on the top of a pyramid and anything that makes truth murky gets put directly below it. Humans, and their understanding of truth, would probably be on the lower/middle half of this Pyramid. Our minds and senses are simply just not developed enough to see the top of the frustum. Saying that reality is truth then is kinda like giving infinite a number, it simply doesn't can't follow universally established axioms.
We can know and can understand a
degree of what is true and what might not be true at all. However, truth as a concept, unlike us, operates in a entirely different realm as we do. It literally is the subject of many believe systems and philosophies for a good reason.
Lets create a simple example. Human eyes can observe colour in many different ways. However, Eagles scientifically can see a wider range of colors than us Humans. So Eagles can natually see a "deeper truth" in colour because of their abilities. Since truth is a state rather than a scale there can only be one truth and anything else is either boils down to be an oversimplification or a lie. Which then means that both the eyesight of the Humans and the Eagles are underdeveloped to see the truth, its just that the gap between us Humans and them the Eagles that also creates this logical bridge, which then helps you to compare these two things together.
But since you can not use the same axiomatic principles to create the same bridge with reality/truth as that would require you to compare it with something of the same scale. You can only compare truth with itself, anything else you must scale, which in turn makes the subject loose some of its reality as it is percepted by us. If you know about Plato you probably heard about the Forms,
its exactly what Plato was getting at with that idea of the forms. Truth simply cannot exist within the realm of the perceptable but instead it must be reduced to a concept in name only.
If anything, only a degree of truth can exist in our world until we're ready to understand propper reality, which requires us to understand anything at once (again, reality is a binary state and not a scale, anything that oversimplifies it then pushes reality out of such a state). Nowadays, only machines might incompletely help but philosophy is still a pretty new subject for us humans after all. 3500 years of advanced cultural development is not a long time IMHO. Its also why I'm posting this kinda, simply because its too early for us to talk about reality unless we're just talking about some concept that might be related to it but judging from my supposed understanding of reality and the history of epistemology it really isn't.
What I mean is, our understanding of truth is only slightly more developed as it even was 2300 years ago. Epistemology as a tool can only take you so far after all. Understanding truth requires an almost (?) impossible amount of factural understanding of reality which is beyond the realm of possibilities, thats all I want to say with this post. This stuff can be quite complicated, yo.
EDIT: I also think people persueing truth are a commendable bunch. It takes a lot of self-criticism, knowledge and wisdom to becomes someone like this and even then those people can and will be prone to biases. I personally doubt we will ever reach the point of "understanding reality" unless we manage to create something that can perform such a task for us instead and where dogmaticism also can't be applied.
