It might be helpful for me to to explain this in some detail. But that Modern man is, indeed, unable to learn from experience is one of the main discoveries of my life. Nothing that has happened, is nothing that ever could happen, will make any difference to the core beliefs of the normal, average, mainstream person of today. I take that observation as proved.
The reason is Modern man cannot learn frm the experiences of his life is that the basic (metaphysical) assumptions - which are explicitly taught in all social institutions, but - more importantly - are implicit in the entirety of mainstream public discourse (political, governmental, legal, educational, medical, mass media - and even church discourse); are that Things Happen either by material causation or by random chance.
When 'something happens' in Life, therefore, it was either merely something that would be expected from understanding the causal factors that led up to it; or else it was merely random chance.
And if The Thing was materially caused, then it has no meaning - it is just an outcome of preceding causes. But if The Thing was just due to random chance, then it also has no meaning, since it Just Happened.
So, it does not matter what happens because - by our frame of reference, by our assumptions, by our fundamental metaphysical convictions - we Already Know that It (whatever It is) has no meaning.
Ultimately this meaninglessness is because we moderns (in public discourse) regard Reality as accidental, not created.
If Reality is created, then it has whatever purpose and meaning is intended by The Creator. But if Reality Just Happened - by some combination of material causation and random chance - then it has no purpose.
Reality Just Is... Just is, whatever it is...
If Reality has no purpose, is not going anywhere (except where material causality and chance happen to be taking it) then Reality has no meaning. Meaning only derives from purpose. Otherwise it is just a case of Stuff Happens (or does not happen, as the case may be).
It is pretty obvious, therefore, why it is that Modern Man does not learn from experience. The answer is that - according to Modern Man's assumptions - learning from one's life is not possible, therefore experience is irrelevant.
(For a typical Modern...) One's life is a mixture of material causality and accidents, it Just Happens, what is there to learn?
We can't do anything about randomness, and even if we know something about material causality, it happens to us anyway, regardless.
For Modern man, life is essentially passive. The only 'problem' is psychologically adjusting to that 'fact'.
What is the alternative? Well, my alternative is to believe the truth that Reality is created (by a loving God), has a purpose, has meaning - and therefore that my Life, my experiences, are tailored to my needs.
I believe that my experience - here, now, in actual life - are designed so that I may learn that which is important for my eternal well-being. My life is-being tailored, designed, such that I can and should learn from experience.
I even believe that this is the case for those who regard the universe as accidental and experience Life as meaningless! Their lives, like mine, are tailored specifcially to teach them what they most need.
The experience of meaninglessness is the lesson that these people need to learn. They need to ask why, and to keep asking. They need to learn that their daily proximate experience of life as meaningless is directly derived from their prior metaphysical assumption that life is meaningless.
Until they address their fundamental assumptions, they are self-doomed. They must recognise that it is their assumptions that deny meaning, not their experience: it is their theory that denies meaning, not the observed facts.
So, such people (most people) cannot ever find meaning in the experience of life, no matter where they look or how diligently they seek...
MIMO: Meaninglessness-in - meaninglessness-out.
