Maybe because psychedelics wake up the part of the human psyche that understands religion
I think of the brain as a "rationalization machine". It observes environmental inputs, and reflexively seeks to ascribe a cause for those inputs. In so doing, a causal model of the world is constructed (whether accurate or not), allowing the agent to make intelligent decisions about what actions to take in order to produce desired outcomes.
What hallucinogenic drugs tend to do is overwhelm the brain with sensory inputs that are sui generis and cannot be folded neatly into a pre-existing causal model of reality, but that are so numerous that they cannot simply be ignored.
So the "protective mechanism" of the brain, rather than abandoning or risking damage to this highly valuable causal model of reality, is to shunt these experiences over into an "other" category of mystical and religious significance. The fact that these experiences are inexplicable, rather than being an indication of any "malfunction" in the brain which might prompt us to doubt our perception in general, is instead proof of their cause: the incomprehensible divine.
This isn't academic, just my 2c.
I don't think whichever one you see is a choice either, more like the yanny vs laurel thing
At one point I made the same argument you make. Now I don't see it that way. And I feel much better honestly
I think you're right that it's a personality thing, maybe connected to how strong the "rationalization drive" is? I don't know.
I guess I'd rather tickle the rationalizing side of my brain with a rationalizination of the tendency to stop rationalizing rather than just stop rationalizing :)
It's important to not become too confident in this either. Our perception of that is as you say useful but also subjective and flawed, and I think if you get down to pure materialism, it's harder to pin down than you may think.
Even something basic which seemingly we all agree on at a basic level and require to function, trying to answer questions like "what is time?", you quickly can end up with mind bendy examples from physics where the intuitive understanding falls apart.
There is no religion, outside of what we imagine. We made it up. It isn’t like the water cycle, it’s not something just waited to be discovered by humans who know how to look for it. Religion is fantasy.
You're making a metaphysical claim here, good luck proving it
Someone mentions religion and you come along and decide to attack it with the same cliche. Why?
Really in all cases, religious and secular, we make the best guesses available to us. I think we need to be humble about all of this.
