This volume investigates the epistemological consequences of the extended cognition thesis, specifically questioning how the integration of environmental features into cognitive processes alters our understanding of knowledge and justification. The editors, J. Adam Carter and colleagues, assemble a collection of essays that bridge the gap between cognitive science and traditional epistemology. By examining the boundaries of the mind, the contributors argue that if cognitive processes extend into the environment, then the epistemic status of our beliefs must also be re-evaluated in light of these external constituents.

Experts in the field identify this volume as a significant contribution to the ongoing debate regarding the externalist turn in philosophy of mind. Readers frequently note the academic density of the prose, which is intended for advanced students and professional philosophers.
