This book gathers together eight essays which are loosely united by the thin thread of gnosticism. In fact, this thread is not long enough to extend to the last three chapters which embrace a different theme, namely, philosophy of religion, broadly understood. The first and second chapters complement each other nicely. The first treats the early gnostics and in so doing raises such basic questions as the complex origins of gnosticism and the multifarious expressions which can be identified under this (...) heading. Hanratty’s specific interest is in the gnostic movement with its “spectrum of ideas and attitudes which formed the many sided heresy of the early Christian centuries”. The second chapter moves from these issues of the early gnostics to a wider investigation of gnostic thought through the centuries. These first chapters provide a useful introductory overview of certain key figures and concepts. Following F. C. Baur’s classification of Hegel as a modern gnostic, Hanratty asserts in the next essay that Hegel’s early development took place within a gnostic framework which subsequently affected his own approach to reality. The next essay turns to Simone Weil and interprets her thought within the boundaries of gnostic elitism. A similar explanation of the ideas of Carl Jung—albeit from the vantage of psychology— is advanced in the fifth essay. (shrink)

The encounter between Socrates and Thrasymachus in Republic I is notoriously baffling. Most of what is said seems straightforward, and the issues at stake are ones of common concern, but the argument remains elusive. The purpose of this paper is to investigate the nature and grounds of this elusiveness, and to show that some of it can be dispelled by a sufficiently free-ranging exegesis that bears in mind the general character of Plato’s writing.

We show how a simple nonlinear dynamical system (the discrete quadratic iteration on the unit segment) can be the basis for modelling the embryogenesis process. Such an approach, even though being crude, can nevertheless prove to be useful when looking with the two main involved processes:i) on one hand the cell proliferation under successive divisions ii) on the other hand, the differentiation between cell lineages. We illustrate this new approach in the case of Caenorhabditis elegans by looking at the early (...) stages of embryogenesis, up to several hundreds of cells (lima bean larval stage). We show how the many results that have been obtained by several groups can be interpreted in terms of values for the parameters controlling the dynamical system. Furthermore, we can extend the model to the cases of genetic mutations. More precisely the teratogenetic and lethal effects are associated with abnormal variation of the control parameters with time.

First published in 1945. In this work the author seeks to correct the misinterpretation and incorrect labelling of Shelley's thought. While not neglecting Shelley as a poet, this book focuses on his contributions made to the general movement of political and philosophical thought of his era and by so doing his relevance to contemporary issues. This title will be of interest to students of literature.
