As part of the 2015–2016 Fellows’ Presentation Series at the Radcliffe Institute for Advanced Study, Michael Pollan RI ’16, the Suzanne Young Murray Fellow, delivered an autobiographical talk—"One Writer’s Trip”—about his thinking and writing on nature as we find it closer to home: the garden, the farm, the table, and most recently, the altered states of consciousness that certain plants and fungi allow us to achieve. These excerpts are from that talk.
