The project of developing a mechanical theory of meaning is beginning to take shape. In the past, scientists couldn’t readily observe a nervous system feeling deep meaning. People aren’t generally hooked up to neuroscience gizmos when the noetic experience strikes. But the return of clinical research into psychedelics is making it easier to provoke these elusive states in the lab, and over the past few years, scientists have begun to develop hypotheses on what these drugs could teach us about the neurobiology of meaningfulness.
