This book needs to be studied! A recent work from Peter Webster (co-writer in the book The Road to Eleusis: Unveiling the Secret of the Mysteries,1978) is available in Kindle.
The presentation of the book:
”KOSMOS presents several arguments, examples, personal experience, and published research to develop the theory that the principal – and perhaps the only important neurocognitive effect of LSD and similar psychedelics is the amplification of perceived salience. The recent characterization of the Salience Network, and a few other recent papers that propose that the psychedelic experience is ”meaning enhancing”, confirm that hypotheses advanced in my early writing in the 1990s anticipated today’s research developments. KOSMOS continues with an evaluation of how psychedelics and salience amplification might have played a role in human evolution, the rise of Greek Civilization, and the radicalization and protest movements of the 1960s. A few personal stories from my past 50 years’ interest in psychedelics spice up the book so that it might be enjoyed by all.
The recent renewal of the study of psychedelic drugs is a welcome but long overdue undertaking. Had such work not been interrupted for many decades, today’s world might be quite different. The present work is an exposition of my own research on the subject, begun in the late 1960s and continuing sporadically ever since. I have attempted to answer not only the obvious questions about psychedelics, but to assemble a comprehensive Theory of Psychedelic Experience, an overview from several perspectives of how a psychedelic experience feels to the voyager, how and why it may affect his views and beliefs, how psychedelic perception happens on a psychological and neurological basis and why it appears to be similar or identical to states of consciousness sometimes attained spontaneously or through meditation and other age-old techniques.”
