...the proper moral purpose of one's life...
To me it stumbles right there - not only asserting the assumption that there is any proper moral purpose, but then going on to act upon the assumption without questioning the assumption.
It seems once again a reflection of so many religions certainty that they can act upon you because they have a 'proper moral purpose' and in this case it's the idea they can act upon you with 'pure laissez faire capitalism'.
You want my moral reflection? I don't know if there is any moral principles in existance, ever, or if there were any, I don't know whether anything I do happens to match such principles.
All I know is that rather than drop limp where I formerly stood and cease breathing or breathe yet lie there till I starve/dehydrate (a bit like the people on that planet in the movie Serenity), I instead feel urge and hunger welling up in me. As intellect I can see this, see the urges coming, and my intellect is powered by these things that well up (you might think of it that these hungers and urges grant intellect a budget...and if they pull the budget, no intellect).
And unlike most people through history who feel such things and pronounce them right and morally just, I have reached the conclusion I can reach no conclusion about whether they are right or morally just or anything.
Anything I do may be monsterous somehow. I do not know.
All I do is at least make sure I'm the sort of monster, if monster I be, that I set out to be. To make sure I'm the monster I decided on, rather than something else that may be equally monsterous AND is not something I decided on.
Then again I don't think souls are for free.
Is there a name used in any particular culture for that?
