The desire for knowledge is an abiding facet of human experience and cultural development. This work documents curiosity as a sociohistorical force initiating research across the disciplines. Projects generated by theoretical curiosity are presented as historical and material practices emerging as expressions of embodied knowledge and experience. The shifting cultural, philosophical and practical relations between theory and curiosity are situated within classical, medieval, early modern and contemporary communities of practice. The practice of theoretical curiosity advocates for a critical, aesthetic engagement in everyday life.
