Abstract

Erickson's article links the concept of four tastes to color perception as a sensory modality with similar problems of categorization. Such problems are also present for odors and olfaction. Olfaction is the sensory modality with the closest physical relationship to taste, and the sense organs of both permanently interact. We discuss the origins and influences of core ideas of the science of smell to add to the discussion of unresolved categorization problems in taste from another, closely related point of view
