Dana Gaynor’s The Journal of Psychospiritual Transformation has some fairly ‘hard’ minded articles about its subject matter. For example, on the contents page of vol.1 you’ll find an article by Charles Tart, “An Emergent Interactionist Understanding of Human Consciousness”. It exemplifies this qualification. On Tart’s site is the best itemization of credible parapsychology resources.
Andrew Cohen’s What Is Enlightenment magazine is good. It’s a bit beleaguered by single-mindedness. (My bias: you can’t praise the mysterium tremendum and also praise only one implied form of ultimate higher consciousness. Creative, ‘messy‘ awareness often gets tossed out in reductive, logos-centric framings of consciousness.)
Hard-mindedness, (a pun if you know what the hard problem is,) is one of the key thrusts of David Chalmer’s web compendium of papers and research on consciousness, the philosophy of psychology, mind, and neuroscience. He’s an editor of the very worthy virtual journal, Psyche.
The Science and Consciousness Review -obviously- is enthusiastically all over the map and includes what old hippy explorers would term research into the doors of perception.
Stephen Jones is behind The Brain Project, another site melding neuroscience and research into consciousness. There is an inviting section of multimedia presentations here.
Did I mention parapsychology earlier? Why yes! What about altered states of consciousness? Two fine resources: Rhea White’s Exceptional Human Experience site, and, TASTE:the archive of scientist’s transcendent experiences, I highly recommend.
