“I have to say that I’m not sure that there is such a thing as “objective” or “absolute” reality. Everything that we think we know is based on assumptions..many of which are commonly accepted, but wrong.”
There is in fact an objective reality. We may not know it, or have the tools to ferret out every detail of it, but we can certainly gather evidence about it and peer-review that evidence and gain an understanding of part of it and use that understanding to, say, build this Internet that we’re communicating upon. Why do I say this is true? Because it works. Because we’ve done it. Because from a utilitarian point of view, positing that there is an objective reality and utilizing the methods of science to gain understanding of parts of it has proven to provide far better results than simply making shit up like the Trumpistas are doing.
Now, granted, our personal interpretations of this objective reality may be wrong. But that doesn’t mean objective reality doesn’t exist. It just means our understanding of this objective reality is incomplete. Which is true by definition, because reality is infinite, while human minds are not. This is why we’ve created techniques to “hack” this limitation. The most important of which is science.
If your notion is that there is no objective reality, then you’re pretty much a mystic cultist, and of little use in a modern society. Hmm… Trump and his supporters… hmm…
