This work investigates the core question of whether a coherent philosophy of mind can exist without a rigorous metaphysical foundation, specifically challenging the Cartesian dualist tradition. Anthony Kenny, a prominent philosopher known for his work on Wittgenstein and the history of Western philosophy, synthesizes his previous inquiries into a systematic critique. He argues that the prevailing Cartesian view of the mind as a separate, non-physical entity is fundamentally flawed and seeks to dismantle its influence on contemporary thought.

Experts recognize this text as a significant contribution to the analytical tradition, particularly for its rigorous dismantling of Cartesian assumptions. Readers frequently note the academic density of the prose, which requires a strong background in philosophical terminology to fully grasp the author's arguments.
