In his attempt to account for the complexity of interactions between an organism and its environment, Jarvilehto (1998) has given us a theory in which organism and environment are considered to jointly constitute a single unitary system. While I support the idea of giving a larger role to the environment than is typical in theories of cognition, I will suggest that Jarvilehto goes too far, erasing the distinctions that are prerequisite to the very possibility of having a theory of cognition.
