Have you ever tasted music or experienced numbers as having genders? If so, you might be a synesthete! Synesthesia refers to subjective experiences in which a stimulus associated with one sensory modality (e.g., vision) is experienced as having properties associated with an entirely different modality (e.g. sound, texture, or smell). This “mixing” of the senses raises fascinating questions about human experience and the life of the mind. In episode 33, Ellie and David discuss the science and philosophy of synesthesia while poking fun at people who brag about being synesthetes at parties. Are synesthetes born or made? What forms of synesthesia exist? And how might one go about cultivating synesthetic perception?
