In Locke's Science of Knowledge, Priselac refocuses on the Essay's epistemological thread, arguing that the Essay is unified from beginning to end around its compositional theory of ideas and the active role Locke gives the mind in constructing its thoughts. To support the plausibility and demonstrate the value of this interpretation, Priselac argues that-contrary to its reputation as being at best sloppy and at worst outright inconsistent-Locke's discussion of skepticism and account of knowledge of the external world fits neatly within the Essay's epistemology.
