It was with my first hit of LSD in 1970 that I started to be conscious of thinking (rationally?) and that (in my environment which was emotionally and intellectually poor and extremely abusive) put me at odds with the most of my world and with time I'd have to say it's only gotten worse for me. Spending long survivalist stretches in the Great Basin alone or with a dog has been the best of it for me.
But I can't honestly say what thinking rationally means? I do know that I can easily see flaws in much of humanities arguments based on my experiences of living and thinking but that is all. I really don't have much going in the way of formal education and am possibly way out of my league here.
Most of what I consider my rational thinking and conclusions would be abhorrent to the vast majority of humanity. For instance embracing Antinatalism. I rationally don't see a "cost effective" way to "fix" what life seems to be. Especially as a human animal. It seems all of us can go in almost all ways due to a little push from chance and chance is not likely to be lucky IME.
