"Sieroka has developed a kind of empirically-informed Husserlian-Leibnizian parallelist account of perceptual and physiological phenomena. ... he develops his views with great rigor, and in many passages brings to bear his perspective on current debates, attesting to the current relevance of his account. The book is very clearly written, rendering the Leibnizian and Husserlian views accessible to a broad philosophical and scientific readership, and providing a framework to organize one's thoughts on the topics of perception and time."
