The paper discusses the debate on the human nature in the sophistic thought. Focusing on the "nature-culture" controversy it presents the evolution of the views of the sophists: from Protagoras' optimistic contention of the progress of mankind and his appraisal of culture to its criticism and the radical turn to nature in Antiphon, Hippias, Trasymachos, and Callicles. The paper aims at presenting the analysis of the ongoing discussion, with the stress laid on reconstruction of the arguments and concepts as well (...) as the attitudes that are associated with various positions of this debate. -/- .

Hermann Hesse (1877–1962), the poet, novelist, man of letters, and painter, created characters who, like the Daoist sages, had many paradoxical characteristics. Some of Hesse’s characters manage their paradoxical natures well and, like the balanced sages, are able to be simultaneously changing yet stable, full of life but also empty, in unison with nature and the social world. Centered between interchanging extremes, these balanced individuals are carefree yet self-controlled, efficacious in their work yet seemingly inactive, and successful in sustaining leadership (...) and power yet humble and non-obtrusive. These sage-like individuals, the ideal leaders presented in the Daodejing 道德經, will be the focus of this essay. Specifically, I will focus on the Daoist hub and wheel analogy, the concepts of wu 無 and you 有, absence and presence respectively, which are extremely important in order to understand the influence of Daoist philosophy on Hesse’s literary examples of sage-leadership.

This thesis examines the Platonic brand in utopian fiction. It looks at Plato's dialogues, H. G Wells' A Modern Utopia and Aldous Huxley's Brave New World. The modern texts provide opportunities to observe the effects of ideas found in the dialogues, helping illustrate their implications for the Platonic utopia. Understanding the implications of Plato's textual criticism found in his dialogues is indispensable in understanding how his dialogues are to be understood and what may be understood to be his utopia. This (...) thesis is divided into four chapters; the first two chapters are further divided into sub-headings to assist with navigation of the argument. The first chapter isolates meaning from vocabulary and sets out Socrates' understanding of the relationship between the two entities. The second chapter proceeds to set out Socrates understanding of the hermeneutic effect on the interplay of his dialectic and interlocutors. The third chapter sets out how Socrates seeks to mitigate the distortion of articulated ideas. The fourth chapter concludes the argument stating that Plato's dialogues can only be understood as a unity, that his utopia cannot have a finality, instead it is fluid, free, continuing, Socratic, dialectic.

This study is inspired by the current debate between the traditional anarchist views, the post-left and post-anarchist understandings of anarchy. It claims that the depictions of anarchy by both sides are primarily negative and develops an original and positive definition of anarchy. In particular, it argues that anarchy is the concept that refers to a way of being with the cosmos and thus instead of being posterior to the political it is in fact prior to it. This is to say, (...) it is neither political nor ontological but can only be seen as metaphysical in the sense of what cannot be spoken of in terms of a primary cause or a founding principle. Methodologically, it follows Martin Heidegger’s understanding of anarchy as an-arché and his idea to look into pre-Socratic, as in non-teleological thought, to define anarchy. But it then adopts Emmanuel Levinas’ approach that anarchy refers to what escapes the thesis- antithesis dialectic. It draws mainly upon Ancient Greek philosophy and literature as this is where anarchy appears as a term for the first time. In particular, it criticizes the Aristotelian ontological and political thought, while it is mainly assisted by the thought of Democritus as the only pre-Socratic whose work escapes ontological thinking. Moreover, the development of a positive definition of anarchy ultimately leads this study to defend the communal nature of traditional anarchism while rejecting its association with the political.

Presenting philosophy properly, in a way that is clear and accessible to our target audience, is of paramount importance. In this essay I draw on my dual experience as a scientist and a philosopher to arrive at some general recommendations for good practice. Specifically, I discuss why presentation matters, whether a bad presentation style is a valid criticism of a philosopher’s work, how we may adapt our message to the variety of communication media available today, and what, if any, is (...) the relationship between how we present and how we conceive of philosophy itself.

Our purpose on the present occasion is to evaluate some ideas the biographers of late antiquity held about the origins of European thought. Speaking about this period we are no longer dealing with the question of transferring of the archaic practices: these practices are indeed long dead. What we encounter can be better defined as the import of ideas. Equally important is a study of the changing attitudes of our authors: rather than passive witnesses, they became active participants of this (...) import. The process is truly fascinating and we hope that the following examples, mostly from Hippolytus, will elucidate this. The best, almost a paradigmatic example is Pythagoras, who in late antiquity had many faces. His biography is an interesting instance of general change of attitude to ancient wisdom, typical for the source utilized by Hippolytus. Looking at a number of peculiar features of Hippolytus’ report which, we hope, will help us to see why the image of Pythagoras and his philosophy, formed by Hippolytus, is somewhat untypical for the period. We will see that Hippolytus’ biographic report, however garbled, shows no signs of so-called ‘Neopythagorean’ biographic development. Admittedly, the later authors frequently combine their sources to make them suitable to their needs, polemical or apologetic. Do we still have a reason to believe that these stories, however doubtful from the historical point of view, may contain the germs of truth? (shrink)
