Demonic geography is an approach to practising human geography that operates from the premise that there are no such immaterial entities as ‘souls’, ‘spirits’, ‘minds’, integrated stable ‘selves’ or conscious ‘free will’. This paper elaborates the theoretical framework of demonic geography by spelling out how it is different from non‐representational theory and by articulating it within recent developments in experimental psychology, neuroscience and the philosophy of mind. Counterintuitively, the paper shows that the deflationary, materialistic ontology of human nature espoused by demonic geography need not lead to meaninglessness, unhappiness or the collapse of moral behaviour. Instead, subscribing to demonic geography opens up new ways to find meaning, to pursue happiness and to live the good life.
