A major obstacle to chemistry being a deductive science is that its core concepts very often are defined in a circular manner: it is impossible to explain what an acid is without reference to the complementary concept of a base. There are many such dual pairs among the core concepts of chemistry. Such circulation of concepts, rather than an infirmity chemistry is beset with, is seen as a source of vitality and dynamism.

This article argues that the figure of Oedipus lies at the heart of Horkheimer and Adorno's Dialectic of Enlightenment. Oedipus is the prototypical Aufklärer as no one can rival him in his courageous attempt to employ his own autonomous reason `without direction from another'; yet self-knowledge remains beyond his grasp. Indeed, Oedipus' obsessive drive to bring the truth to light ultimately leads him to put out his own eyes because he is unable to bear the sight of the catastrophe that (...) this drive engenders. Oedipus' demise represents in allegorical form the self-destruction of enlightenment itself. Enlightenment is similarly driven to illuminate the world in its totality by reducing it to philosophical concepts. In the process, however, it becomes blind to the question of its dependence upon that which it purports to possess. In its attempt at total illumination, therefore, enlightenment does not effectuate an exit or Ausgang from the opacity of myth, as Kant had held, but rather is blinded, paradoxically, by the radiance of its own projections. Reading the dialectic of enlightenment through the tragedy of Oedipus leads back to the enigmatic question of art as the means by which the rationalization and disenchantment of the world can be reflected upon critically.

This interdisciplinary article argues that ancient Greek and Roman representations of Okeanos, Tartaros, and the underworld demonstrate an observational awareness of the hollow underground spaces that characterize the geomorphology of karst terrains in the Mediterranean world. We review the scientific facts that underlie Greek and Roman accounts of karstic terrain in observation-based discourse and in myths, and we demonstrate that the Greek words barathron, limnē, koilos, and dinē are used with precision in observational accounts of karst terrain. Ancient accounts of (...) the dynamic limnē and barathrum systems characteristic of much karst terrain offer a complex matrix of observation-based and belief-based discourse: at the edge of the barathrum, the imaginative or spiritual realm of the underworld has a material plausibility and the closely observed material world has a plausible potential to connect to a world we cannot see.

This article discusses the Homeric background of the Republic with the aim of elucidating Plato’s critique of Homeric nostos. It argues that the Republic unfolds as a nostos voyage, with Socrates striving to steer the soul home. Even though Segal has already argued for seeing the Republic as an Odyssean voyage, this article suggests that Plato does more than simply borrow the idea of a voyage as a metaphor for the wanderings of the soul. Rather, there is an implicit critique (...) of Homer as the “poet of Becoming” in the dialogue. Thus, reading the Republic in the context of other Platonic dialogues such as the Cratylus and Theaetetus where Socrates identifies Homer as the source of the view that Ocean is the origin of all things and that everything is in flux allows us to better appreciate Socrates’ critique of poets in the Republic. At stake in this critique is ultimately the question of the soul’s true nostos, which Plato identifies with a vertical ascent to Being rather than with a temporary homecoming within Becoming. This article contributes to the elucidation of the Homeric and pre-Socratic background of Platonic philosophy. It undertakes a literary reading of the Republic against the background of the hero’s journey motif. Specifically, it argues that Plato critiques and emends the Odyssean nostos in order to make space for Parmenidean ontology, thus forging a new understanding of salvation. (shrink)
