"On Nature Physics, Book II" is the most important of the Aristotelian works on matters relating to the philosophy of nature. It contains the most complete version of Aristotle's theory of the four causes. Aristotle attempts to chart a middle between the Platonic idealism and the materialism of the last pre-Socratic philosophers. This volume includes an extensive introduction and copious commentary by Vassilis Kalphas, Professor of Philosophy at the University of Crete, who has also published his work on Plato's "Timaeus".
«"On Nature" is a work that enriches and elevates the science of philosophy in Greece.»
