We destroy our rational mind through the way we misuse language.
How? We lose track of what we are referring to and become tangled in subtext, fanciful metaphor, poetic digression, and 'spiritualizing' our imagination.
Is poison a good thing to drink? No. That is true because it is demonstrable.
It is a useful and practical thing to know. It is factual.
What about taking a slow poison? Doesn't it bring about eventual death?
A lifetime of exposure to a socially approved form of irrational non-fact cannot be healthy. It is slow poison.
Civilization has been held in thrall by superstition almost from the very beginning. Mankind staggers about drunk on non-fact because it is inebriated by religious poison.
What is true is demonstrable in a real way.
That other sort of 'true' is bullshit, no matter what the numinous source may be said to be.
Superstition makes claims, creates fear, makes murky what is plain, and otherwise disconnects us from everyday reality.
If you find yourself confused by some 'truth' you are told--maybe, just maybe it is superstition and mysticism instead of fact.
