lol - no, I realize it doesn't have to be related.

....evolution in consciousness

?????

My point was that the further away from these basics you go, the more abstract it becomes (evolution in consciousness?)

So to make these purposes as real as possible, requires a self induced 'fooling of oneself', to 'make it' as real as possible.
But it never will be - it never can be.
Food shelter sex is the reality, the rest is degrees of a self convincing argument forcing other purposes to take the mantle of 'just as real'.

....you see what I mean?

Still don't mean to be nihilistic....

One might argue simply based on Maslow's hierarchy of needs that even a caveman would find better things to do if his needs for food, shelter, and sex were indubitably covered for life.

Maslow aside, learning could be argued to be the best way to ensure your own continued existence (unless you already decided your 'soul' is immortal). I'm not just talking about 'becoming immortal'; whether you lived centuries ago and learning about herbs or a snake could save your life, or you live in the present with the dangers of wasting away due to a lack of knowledge about the importance of diet, exercise, stress management, etc. Thus, to anyone who doesn't flinch away from the truth or escape thought altogether, our survival needs really aren't covered as well as they could be.
