This book is about structural relations between phenomenological and neurophysiological aspects of consciousness and time. Focusing on auditory perception and making new and updated use of Leibniz and Husserl, it investigates the transition from unconscious to conscious states, especially with regard to the constitution of phenomenal time.

"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." (Kristjan Laasik, Phenomenological Reviews, reviews.ophen.org, December, 2015)

Norman Sieroka received a Ph.D. in Physics from the University of Heidelberg, Germany, working in auditory research and on the neurophysiology of time perception. He earned an M.Phil. in History and Philosophy of Science from the University of Cambridge, and both a Ph.D. and Habilitation in Philosophy at the ETH Zurich, where he is currently employed as a senior researcher.
