you believe you are absolutely and unquestionably right about this. Even though you cannot know or prove this to be so.
I didn't get that from him, but I do get it from you. His words were, "Its more then that, it's real, from whatever way you look at it. Oxygen is Oxygen. It doesn't need to be relative to something else." Most educated people understand that there is some uncertainty about what exists outside of conscious experience.
Reality only exists in our heads. Including the reality of 'oxygen'.
This is you being unquestionably right again. And a radical solipsist / epistemic nihilist.
I have a very pragmatic approach to knowledge and reality. Ideas that allow one to anticipate outcomes can be called knowledge. We don't need to burden ourselves with philosophical vanities when going about our days.
The value of such knowledge is in informing decisions and driving actions which then influence events in the external world and lead to objective consequences. Take away any of these elements and truth immediately loses all relevance. We should expect similar decisions made under similar circumstances to lead to similar outcomes.
The ultimate measure of a true or false proposition lies in its capacity to produce expected results. An idea called true or correct by this reckoning can be used in the real world to generate predictable consequences, and different ones if that idea turned out to be false.
We don't need to fret about absolute or objective or ultimate truths. All we need to know is that we have desires and preferences, we make decisions, and we experience sensory perceptions of outcomes. If a man has belief B that some action A will produce desired result D, if B is true, then doing A will achieve D. If A fails to achieve D, then B is false. Either you agree that truth should be measured by its capacity to inform decisions and produce results or you don't.
You seem to have some other idea of what truth or knowledge is. To you, it is ethereal and unobtainable. Is there anything true about oxygen to you?
Are you familiar with
logical positivism or
verificationism? About a century old now, they're essentially the opposite of your position and probably something you'd classify as scientism.
You cannot understand this because you are a true believer. You have joined the cult of the scientific materialists. And now your mind can no longer think outside of that box.
Fortunately, we have visionaries like you who have successfully avoided cultic thinking and seen further.
You are unable to recognize that how you understand the world and how the world is are not the same. And in fact could be wildly different without you or I ever knowing.
You are so much more perceptive than those still thinking in the box. Who (besides you) knew that there might be as yet undiscovered aspects of reality?
You're playing a game. You've cast yourself in the role of the visionary. It's pretty common. I guess people like to invent superpowers for themselves. They like the idea of possessing arcane knowledge unavailable to the uninitiated. It's related to the people who want there to be more magic in the world and to have access to magical powers. I think it drives a lot of New Age thinking and ritual.
I don't have that need or desire. I wonder why not. I can see critical thinking in that light to some degree. It could be called a ritual that allows one to see further. It allows one to accumulate knowledge as I've defined it, which is a superpower of sorts. Maybe that's why I don't find value in these other ways of knowing. Maybe that's why I'm not searching for gods.
