According to Aristotle, the "object" of study of the first philosophers was the φύσις. Even though the term appears for the first time in Heraclitus, the early answers to the question "what is the 'being' of τὰ ὄντα" present already it as a source of active and dynamic life, according to the etymology of φύσις. This is the meaning in Homer (Od. X.303), and this is also the case of water (Thales), air (Anaximenes), and the γόνιμα contained in the φύσις (...) ἄπειρον (Anaximander, apud Ps.-Plutarch). The φύσις of Heraclitus inherits this meaning, because, for him, reality, "changing, is at rest" (fr. 84a). (shrink)

_Process Philosophy_ surveys the basic issues and controversies surrounding the philosophical approach known as “process philosophy.” Process philosophy views temporality, activity, and change as the cardinal factors for our understanding of the real—process has priority over product, both ontologically and epistemically. Rescher examines the movement’s historical origins, reflecting a major line of thought in the work of such philosophers as Heracleitus, Leibniz, Bergson, Peirce, William James, and especially A. N. Whitehead. Reacting against the tendency to associate process philosophy too (...) closely with this last-named thinker, Rescher writes, “Indeed, one cardinal task for the partisans of process at this particular juncture of philosophical history is to prevent the idea of ‘process philosophy’ from being marginalized through a limitation of its bearing to the work and influence of any one single individual or group.” This book will appeal to both students and professors of philosophy. Those teachers who have not been trained in process philosophy will welcome this new text by one one of North America’s foremost philosophers as a perspicuous and informative introduction. (shrink)

Protagoras, of all the ancient philosophers, has perhaps attracted the most interest in modern times. His saying ‘Man is the measure of all things’ caused Schiller to adopt him as the patron of the Oxford pragmatists, and has generally earned him the title of the first humanist. Yet the exact delineation of his philosophcal position remains a baffling task. Neumann, writing on Die Problematik des ‘Homo-mensura’ Satzes in 1938,2 concludes that no certainty whatever can be reached on the meaning of (...) the dictum, since ‘man’, ‘measure’, and ‘things’ are all ambiguous, nor can we tell which of the three is the predicate. The time is past when it was believed that a man's philosophy could be understood apart from the events of his life and the circumstances of his age: yet in the case of Protagoras the historical method of approach has hardly been attempted, although the impact of environment was perhaps more decisive in the formation of philosophical concepts in the Greek world than anywhere else. The reality about which the Greek philosopher spoke had three aspects: it was either the one universe of physics, or the political unity, or God. For example, the book of Heracleitus Περ φσεως was divided into three chapters or logoi, About the Whole, a political, and a theological. Neither physics nor theology supplies from its own subject-matter the form in which this reality was described. (shrink)

The saying reads, "The waking have a single cosmos in common," i.e., a single world-shape in which they take part in common. By this is already expressed what the later moral philosopher Plutarch, who preserved the fragment for us, pointed to in his interpretation: in sleep each turns away from the common cosmos and turns to something which belongs to him alone, something thus which he does not and cannot share with any other. That Heracleitus himself, on the contrary, (...) understood this less as the sleep of an individual, including the sphere of dreams, than as a cosmos, one among numberless fleeting world-shapes, in no way corresponds to what we know of his teachings.

After comparing Fr. 6 with the literature of its day, Mansfeld concludes that Parmenides' poem is not a polemic against Heracleitus. Rather, the poem reflects an opinion of the low estate of human knowledge not uncommon in that day. This does not, of course, preclude any influence of Heracleitus on the poem. In a second chapter, Mansfeld analyzes the argument of Fr. 3 as a disjunctive syllogism and argues that Parmenides is the founder of a tradition of logic (...) continued by Zeno, the Megarians, and the Stoics. The final chapters are devoted to a discussion of the Doxa and the central place of the Proem in interpreting the poem as a whole. The book contains an extensive bibliography, topical index, and index of Greek texts.—O. J. L. (shrink)
