Jeremy Sherman set out, fairly early in life – to be a hippie. He now asserts that science is his spiritual path. Possessing a naturally questioning mind, Jeremy abandoned the quest for undefined enlightenment to seek out answers to higher truths by applying scientific methods. Working closely with Harvard and Berkley neuroscientist and biological anthropologist Terrence Deacon he seeks to explain the basis on which biological organisms aspire or try. He told me that this aspect of life – trying or aspiring or dreaming, so to speak – distinguishes living organisms from machines. It has names but little in way of explanation.
