Towards the close of Book V of theRepublicPlato tells us that the true philosopher has knowledge and that the objects of knowledge are the Forms. By contrast, the ‘lovers of sights and sounds’, he tells us, have no more than belief, the objects of which are physical particulars. He then goes on to present us with some very radical-sounding assertions about the nature of these physical particulars. They are bearers of opposite properties, he says, in so thorough-going a manner that (...) we cannot say of them that they are nor that they are not: they lie somewhere between being and utter non-being.This passage of theRepublic still awaits an agreed interpretation and I want to suggest as a reason for this that it is usually interpreted in isolation. I will argue that it becomes easier to understand when seen against the background of Plato's developing thought. To be more precise, it makes sense when taken as a rejection by Plato of one of his earlier beliefs: namely, a doctrine of essentialism to be found in thePhaedo.The greater part of this paper then will be an attempt to show thatRepublicV is a rejection of thePhaedo'sdoctrine of essences. Its concluding part will try to explain why that doctrine was rejected. (shrink)

In Cornford's opinion, the theory of Forms as put forward in theParmenides is identical with the theory as stated in the Pbaedo—both of them expressing thethat concrete things are the bearers, simultaneously, of contrary characters. Christopher Kirwan has recently denied this identity, in a paper which, if hisis accepted, will upset many traditions and greatly alter our understandingLthe middle dialogues.

In this paper I wish to argue for a view that, despite its traditional standing, has not yet in any detail been defended. The view is briefly that in the Republic, at the point where Plato is engaged in contrasting the true philosopher with the “lover of sights and sounds”, he characterises sensible particulars — referred to as “the many” — as being bearers of opposite properties in so radical a manner that they can be said neither to be nor (...) not to be: they lie somewhere between being and utter non-being.There are two related reasons why this traditional view should now be closely scrutinised. The first is that, whatever the outcome, the passage of the Republic in question — 475a-480a — is quite crucial to our understanding of the development of Plato's thought about sensible particulars. The second’ is that it has been suggested recently, and ably argued, that Plato is not in fact talking about particulars at all; rather about types or sorts of particulars. (shrink)

First published in 1931 and originally delivered as the Deems Lectures at New York University in 1929, this book examines what scientific discoveries in many different branches of science reveal, and the implications of such discoveries for philosophy. Esteemed philosopher F. S. C. Northrop surveys a variety of advances, including relativity and quantum mechanics, and how they correlate to his epistemological theory of concepts. This book will be of value to anyone with an interest in the history of science and (...) the connection between science and philosophy. (shrink)

The biological sciences study (bio)complex living systems. Research directed at the mechanistic explanation of the "live" state truly requires a pluralist research program, i.e. BioComplexity research. The program should apply multiple intra-level and inter-level theories and methodologies. We substantiate this thesis with analysis of BioComplexity: metabolic and modular control analysis of metabolic pathways, emergence of oscillations, and the analysis of the functioning of glycolysis.

This is a book about the philosophy of Henri Bergson which shows how relevant Bergson is to much contemporary philosophy. The book takes as its point of departure Bergson's insistence on precision in philosophy. It then discusses a variety of topics including laughter, the nature of time as experienced, how intelligence and language should be construed as a pragmatic product of evolution, and the antinomies of reason represented by magic and religion. This is not just another exposition of Bergson's work. (...) It offers an account of why Bergson commanded such a massive reading public in his own day and why he deserves to be read now. Written in a terse and clear style, this book will prove appealing to teachers and students of philosophy, cognitive science, psychology, religious studies and literature. (shrink)

This paper attempts to respond to a call to find an ontological basis for establishing African legal theory. The African world of my choice is the Igbo world of South-east Nigeria. It is a world I want to examine to see how its material and theoretical structures help articulate a philosophy of law in terms of projecting a consistent understanding of law subjects and the foundations of their rights. The article builds on the contributions of F. U. Okafor and his (...) many African critics. (shrink)
