En el presente trabajo intentaremos poner en evidencia un singular enfoque sobre la pólis ateniense ofrecido por Protágoras en el diálogo platónico que lleva su nombre. Dicho enfoque, soslayado por los intérpretes, hace hincapié en la dimensión visual de la praxis política de los ciudadanos y es coherente con los posicionamientos ontológicos que emergen de los fragmentos del sofista.

With the use of a particular metaphor, which appears at the end of the Cratylus and is taken up with perfect symmetry at the beginning of the Theaetetus, Plato certainly wanted to indicate the succession of Cratylus–Theaetetus as an order for reading the two dialogues, which Trasillus faithfully reproduced in structuring the second tetralogy of Platonic dialogues. The claim of the theory of ideas, with which the Cratylus ends, must therefore be considered the background in which to place not only (...) the analysis of the name carried out in the Cratylus, but also the discussion and criticism of the epistemological theories examined and refuted in the Theaetetus. The transition from the discussion of the name to that of the logos is another important theoretical element that connects the two dialogues. Another one is the theory of knowledge, already precisely elaborated in the Cratylus, and taken up and deepened in the Theaetetus. Finally, the theme of false and error is a third theoretical element common to the two dialogues, which, starting from Euthydemus, finds its solution in the Sophist. (shrink)

This article will contrast two portrayals of Protagoras: one in the "Theaetetus," where Socrates discusses Protagorean theory and even comes to his defense by imitating the deceased sophist; and another in the "Protagoras," where Socrates recounts his encounter with the sophist. I suggest that Plato wants listeners and readers of the dialogues to hear the dissonance between the two portraits and to wonder why Socrates so distorts Protagoras in the "Theaetetus." Protagoras in the "Protagoras" behaves and speaks in ways that (...) are incompatible with the Protagorean position presented in the "Theaetetus." . (shrink)

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. -/- .
