PLANTS, OF COURSE, are subject to as much moralizing as anything else. They provide our essential power—the energy to live, the medicines to be cured of diseases, the materials for clothes and shelter, and the relief from ordinary, everyday experience. In preparing this section, we were shocked by how many books on all aspects of plant power had disappeared. It felt like modern humans wished to hide, and in some sense, deny the massive vegetative influences in their lives. So, with respect and rebelliousness, this cluster has mostly out-of-print books. Hopefully, the carrots and the ayahuasca understand.
