Its earliest version was read by my colleague and friend, Shabtai Unguru, and criticized in many heated discussions. I thank him for his patience and insistence on proof for everything. Special thanks go to Antony Lloyd who so freely and generously donated his time and deep scholarship to a complete stranger. His detailed criticism of the first half of the book helped me steer clear of many errors, clarify many arguments, and drastically readjust the book's perspective. Niza Dolav, my close friend and assistant during all these years, gathered (sometimes unearthed) the literature I needed, typed the infinite number of my longhand drafts and the whole book several times as it metamorphosed. She created the whole apparatus, gave the book its final look before going to the publisher, and finally proofread both galleys and the page proofs. I wouldn't have completed the book but for her devotion and determination. My wife Nira has been my daily love-support system and no words can express my gratitude to her. page_xi Page 1 Introduction: The Idea Of Anti-Informationism 1. Tradition: Forms into Forces Our traditional perception of Aristotle's philosophy of nature takes it as a kind of dynamics, a theory of forces that cause the motions of the world. This tradition interprets his concept of ''nature" by taking what he calls "beginning" or "principle" or "origin" (arche *) as some kind of a force, and the "internal origin of motion" (arche* kineseos* en auto(i)*, which is Aristotle's formal definition of "nature") as "a power, resident in natural objects" (Ross, 1936: 25). This initial step is next followed by linking the "internal power" with potentiality for motion, and potentiality (dunamis) now becomes a power or force resident in natural objects, causing their natural motions. From such humble beginnings, this traditional reading of Aristotle molds him into a sobered-up Plato, namely, a Plato without a world of Ideas. Aristotle took these, so it is suggested, and transformed them into indwelling entities residing within natural objects. These, in their new role, he renamed "forms," but apart from these two variations he left them intact as he found them in Plato. In particular, Aristotle's forms remain causative as "powers, resident in natural bodies" (Ross, ibid.) acting on these bodies from within as their immediate movers in their natural motions. "Nature or essence" is the indwelling form that is "an internal power of originating movement" as Ross put it (ibid: 24), or as a recent scholar writes, it is the "developmental force which impels it [the body] toward the realization of its form .
