I presume :) everyone here has reviewed all the abstracts, workshops, posters, and sessions at next month's TSC 2020 conference: http://consciousness.arizona.edu/ abstracts: https://eagle.sbs.arizona.edu/sc/abs_report_bysession.php?p=C (Does anyone have a presentation there?) What approach to consciousness is missing from this gazillion collection of presentations? @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
