To conflate culture with ideology is quite an obscene level of sophistry.
Only dilettantes, chronic dope smokers, dreamers, New Agers, and dirty communists buy such a line. Intelligent people of self-mastery and refined skills would never stoop to such a low level of arrogance, ingratitude, and ignorance.
Culture isn't something merely handed down and unthinkingly consumed. It is a legacy of knowledge and tools on which we can build on, and draw on for the attainment of truly creative, intellectual and moral development, and the achievement of truly refined skills.
Culture is civilization, and Civilization is culture.
If you hate civilization, you are foolish. The monster within is present always, civilization or not. Rousseau was wrong. Civilizations are felled by the uncivilized, or the de-civilized. Opulence and corruption. The civilizing forces are those things that subdue excess, sloth and impulse, discipline the beast and lead us to achieve our true human potential.
Holy shit on a stick I despise that McKenna and his weedy reedy slimy voice more with each year I age! And so many false prophets and hippies like him. They react to neuroses of our time but provide nothing but pipe dreams and spiritual cyanide leading to far worse neuroses and madness.
You know what our cure is? Hard work, self-discipline, service to others.
