Objeciones a la tesis de la mente extendida (I): Sobre el contenido intrínseco y la marca de lo cognitivo

Adams y Aizawa formularon así la cuestión:

"A Ž first essential condition on the cognitive is that cognitive states must involve intrinsic, non-derived content. Strings of symbols on the printed page mean what they do in virtue of conventional associations between them and words of language. Numerals of various sorts represent the numbers they do in virtue of social agreements and practices. The representational capacity of orthography is in this way derived from the representational capacities of cognitive agents. By contrast, the cognitive states in normal cognitive agents do not derive their meanings from conventions or social practices. Despite possible interpretationist perversions to the contrary, it is not by anyone’s convention that a state in a human brain is part of a person’s thought that the cat is on the mat" (2001, p. 48).
