In book IX of the Republic, Socrates offers a strange mathematical calculation, which claims to prove that the tyrant lives exactly 729 times less pleasantly than the king. For the first time, a complete and detailed reconstruction of this difficult text and its underlying structure is offered in the present article. It thereby proves that the distinction between ‘pleasure’ and the ‘image of pleasure’ is one among the keys to understanding the passage. It is furthermore shown how the whole calculation (...) is based on Plato’s ontology of dimensions and therefore proves that this theorem can be taken into account at least already for the time of the Republic.

I discuss Aristotle’s opening argument against Platonic Forms in _Metaphysics_ A.9, ‘the Razor’, which criticizes the introduction of Forms on the basis of an analogy with a hypothetical case of counting things. I argue for a new interpretation of this argument, and show that it involves two interesting objections against the introduction of Forms as formal causes: one concerns the completeness and the other the adequacy of such an explanatory project.

Plato's Republic critiques Athenian democracy as practised during the Peloponnesian War years. The diseased city Socrates attempts to purge mirrors Athens in crucial particulars, and his proposals should be evaluated as counter-weights to existing institutions and practices, not as absolutes to be instantiated. Plato's assessment of the Athenian polity incorporates two strategies -- one rhetorical, the other argumentative -- both of which I address. Failure to consider Athens a catalyst for Socrates' arguments has led to the misconception that Plato was (...) dogmatically committed to a single political doctrine for all and for all time.

The paper concerns the refutation of Polus (474c-475e). My approach to the refutation is to give a logical analysis of the argument and the fallacy in it. I argue that the verbal nature of the refutation is a valuable key to understanding the special emphasis that Plato places on the sophistic misuse of language.

I argue that Plato distinguishes between personal immortality and immortality of the soul. I begin by criticizing the consensus view that Plato identifies the person and the soul. I then turn to the issue of immortality. By considering passages from 'Symposium' and 'Timaeus', I make the case that Plato thinks that while the soul is immortal by nature, if a person is going to be immortal, they must become so. Finally, I argue that Plato has a psychological continuity approach to (...) personal identity. Thus, for Plato, a person becomes immortal by avoiding reincarnation and securing for themselves psychological continuity forever. (shrink)

Alcibiades relates Socrates' warning on his proposal for a reciprocal exchange of beauty; he should take a better look in case he is mistaken about Socrates' beauty and true worth: ἥ τοι τῆς διανοίας ὄψις ἄρχεται ὀξὺ βλέπειν ὅταν ἡ τῶν ὀμμάτων τῆς ἀκμῆς λήγειν ἐπιχειρῆι· σὺ δὲ τούτων ἔτι πόρρω, ‘the sight of the mind, you know, begins to see sharply when the sight of the eyes attempts to fade from its prime—but you still far from these.’.

The article explores E.M. Forster’s story The Machine Stops as an example of dystopian literature and its possible associations with the use of technology and with today’s cyber culture. Dystopian societies are often characterized by dehumanization and Forster’s novel raises questions about how we live in time and space; and how we establish relationships with the Other and with the world through technology. We suggest that the fear of technology depicted in dystopian literature indicates a fear that machines are mimicking (...) the roles that humans already play in relational encounters. Our relationship with machines frequently suggests a classical “I-it” situation. However, a genuine dialogue is where there is no master and where communication and understanding are achieved through the encounter and through openness to difference and to change. The article examines the ways machines and automata are imagined and become part of lived human existence, in the light of Martin Buber’s philosophy of dialogue and Merleau-Ponty’s phenomenology of perception and otherness. The problem seems to be how everyday technological interfaces can change the way we first perceive the world and the possibility that with certain types of mediation there is a loss of connection with the Other. It is argued that understanding dialogical conditions could help turn the relationship with technology into something more humane. Literature such as Forster’s is considered as an example of such a dialogical condition, suggesting ways of dealing with human dilemmas by exploring the field of possibilities. (shrink)

Does the Longer Way, described but not taken in Plato's Republic, provide understanding that justice and other virtues are good? Sarah Broadie argues that it does not, on the grounds that Socrates and the brothers learn about justice's goodness without taking the Longer Way. I argue that Socrates’ arguments for justice's goodness are not so complete as to make it impossible for philosopher-rulers to gain from the Longer Way greater understanding of the same point. My main textual evidence is a (...) passage of Book IX (589b–c), a summary that has been widely underappreciated. (shrink)
