" This astounding success is owing to one of the cleverest evolutionary strategies ever chanced upon by a plant: the trick of producing a psychoactive compound that happens to fire the minds of one especially clever primate, inspiring that animal to heroic feats of industriousness, many of which ultimately redound to the benefit of the plant itself. For coffee and tea have not only benefited by gratifying human desire, as have so many other plants, but these two have also assisted in the construction of precisely the kind of civilization in which they could best thrive: a world ringed by global trade, driven by consumer capitalism, and dominated by a species that by now can barely get out of bed without their help.
