The document is a critical notice of Andy Clark's book *Supersizing the Mind: Embodiment, Action, and Cognitive Extension*. The notice, written by Robert D. Rupert, University of Colorado, Boulder, evaluates Clark's arguments and responses to critics. Rupert argues that Clark's extended view of cognition, which posits that the human mind includes elements beyond the organism, faces significant challenges. He critiques Clark's arguments for the extended view, particularly his reliance on phenomenological experiences and evolutionary arguments, and suggests that the nonextended, situated approach (HEMC) is more plausible. Rupert also addresses Clark's rejoinders to his own criticisms, clarifying the original argument and refuting misunderstandings about the Parity Principle and other concepts. He concludes that the nonextended, systems-based view is more consistent with the nature of cognition and the role of the environment in cognitive processing.The document is a critical notice of Andy Clark's book *Supersizing the Mind: Embodiment, Action, and Cognitive Extension*.
