 Dretske and Martin have argued against experience conceptualism on the grounds that it cannot reflect the informational richness of experience (see Dretske 1981, Martin 1992a, see also Bermudez and Macpherson 1999) and Chuard (2007). The main idea that experiences can (and typically do) convey information about so many objects, properties and relations in the environment that it is implausible to suppose in those cases that the subject could possess and deploy concepts for every object, property and relation that experience represents. The richness argument thus has two main parts: the first part defending the alleged phenomenal and informational richness of experience; the second defending that inference from richness to the falsity of experiential conceptualism.
