This book examines an overlooked "tradition' of aesthetic geometries in ontological philosophy. Developed through Kant's aesthetic subject, I explore a trajectory of geometric thinking and geometric figurations in ancient Greek, post-Cartesian and twentieth-century Continental philosophies, through which productive understandings of space and embodied subjectivities are constructed. The discussion has a twofold purpose: first, it seeks to disrupt the "natural' relationship between geometric ideas or figures and limited forms of scientific "truth', and second, it promotes the importance of aesthetic sense in the production of geometric thinking. I therefore outline an alternative tradition of geometric methods and figures which resist being reduced to simple repetitions of scientific geometric thinking.
