The first volume of the new series "Anthropological Psychiatry" impressively demonstrates how philosophical reflections on the nature of humanity enrich social and somatic psychiatry, medicine, and psychology. They not only provide access to new therapeutic approaches but also promote the necessary discourse among all actors in psychiatric professional and experiential fields. Where exactly are the boundaries between forms of delusional psychosis and other psychological phenomena? What distinguishes creative alienation from the familiar from invention mania, and what separates mass delusion from collective beliefs? In other words: Where do psychotic and "normal" human perception and processing capabilities meet and intersect? This new standard work reviews psychiatric and philosophical knowledge and showcases the entire spectrum.
