"What, then, was the knowledge that God wanted to keep from Adam and Eve in the Garden? Theologians will debate this question without end, but it seems to me the most important answer is hidden in plain sight. The content of the knowledge that Adam and Eve could gain by tasting of the fruit does not matter nearly as much as its form—that is, the very fact that there was spiritual knowledge of any kind to be had from a tree: from nature. The new faith sought to break the human bond with magic nature, to disenchant the world of plants and animals by directing our attention to a single God in the sky. Yet Jehovah couldn’t very well pretend the tree of knowledge didn’t exist, not when generations of plant-worshiping pagans knew better. So the pagan tree is allowed to grow even in Eden, though ringed around now with a strong taboo. Yes, there is spiritual knowledge in nature, the new God is acknowledging, and its temptations are fierce, but I am fiercer still. Yield to it, and you will be punished. So unfolds the drug war’s first battle."
