It has been argued that Kant's all-consuming efforts to place autonomy at the center of philosophy has had, in the long-run, the unintended effect of leading to the widespread discrediting of philosophy and of undermining the notion of autonomy itself.

Ameriks challenges the presumptions that dominate popular approaches to the concept of freedom, and to the interpretation of the relation among the Enlightenment, Kant and post-Kantian thought.
