ABSTRACT
Philosophers may disagree with unmatched zeal, but no philosophical controversy can free them from their common dependence upon the concept as a privileged vehicle of truth. Even when embracing the most radical empiricism or the most unyielding skepticism, philosophers cannot help but make conceptual arguments. All their efforts may aim at curing themselves of addiction to the concept, but so long as they reason in behalf of experience or the suspension of judgment, thinking remains the element in which their claims live and die.
