I think i see what you are getting at. And you are right, that we are shaped by our culture and the learning we receive/do. I still hold that even out of this, you can bring forth something new...at least as far as something like widsom/knowledge goes *. If you as a person can count as something "new" (and/or your views as a whole) ... i guess that's a very philosophical question. I cite the "you are more than the summ of your parts" quote and be done with it... i guess it shows in what direction i lean **

I think you also underestimate the value of "twist and turn" in that context? A lot of new stuff came out of starting by twisting and turning old stuff and then, suddenly, discover something totally differen/new.
*if that were not the case, science would be forever stuck in a circle where we discover nothing new...and that is demonstrably not the case.
** so from that angle, there IS room for "your" idea. Because it is very much probable that the exact "composition" of what makes your view/idea/etc. is unique and has never been here before.
