why neoclassical economics bites....in 3000 beautiful words

So...i think i can give this whole academic caper up. happened upon this essay - http://www.paecon.net/Fullbrook/Descartes.htm - by edward fullbrook on google whilst looking up definitions of the word 'intrasubjectivity"...(y'know 'to google' has entered the english vocab but i reckon their should be a word that refers to online happenstance occuring when googling for something else.)

anyway this guy pretty much says exactly whay i want to one day be able to say in response to everything i have been taught about neoclasscal economics. but he has said it already. so i should just go and play guitar. turns out the problem with neoclassical economics is descartes. i supected as much.
