Abstract

I criticize Sacks' ambitious work on objectivity and its history in modern philosophy in three main regards: First, Sacks tends to oversimplify the different views of Descartes, Locke, and Hume, which are not all haunted in the same sense by a "subject-driven skepticism". Second, Kant's conception of objectivity isn't directed (primarily) at refuting external world skepticism. Third, Sacks assumes that it is clear what transcendental idealism is: a doctrine that asserts an ontological distinction between "appearances" and "things in themselves". This ignores the deep interpretive and systematical discussions about this doctrine. In sum, the book lacks a proper historical diagnosis of where current notions of objectivity come from, or how our agenda has changed from those of early modern philosophers.
