I’m still an atheist, and I still accept that those scientists who seek to reduce consciousness to matter may be right. But my experiences with Ayahuasca have convinced me, as no amount of reading or studying or listening to lectures or sermons ever could, that materialist-reductionism is a profound error, that to be alive and conscious at all is a mystery of enormous, immeasurable proportions and, in brief, as Shakespeare put it in Hamlet, that “there are more things in heaven and earth” than are presently dreamed of in our philosophy.
