There have in recent years been at least two important attempts to get to grips with Aristotle's conception of dialectic. I have in mind those by Martha C. Nussbaum in ‘Saving Aristotle's appearances’, which is chapter 8 of her The Fragility of Goodness, and by Terence H. Irwin in his important, though in my opinion somewhat misguided, book Aristotle's First Principles. There is a sense in which both of these writers are reacting to the work of G. E. L. Owen (...) on cognate matters, particularly his well-known paper ‘Tithenai ta phainomena’. Owen himself was in part reacting to what I suppose is the traditional view of how Aristotle regarded dialectic, as revealed in Topics I. 1. On that view dialectic is for Aristotle a lesser way of proceeding than is demonstration, the method of science. For demonstration proceeds from premises which are accepted as true in themselves and moves from them to conclusions which follow necessarily from those premises; and the middle term of such a demonstrative syllogism then provides the ‘reason why’ for the truth of the conclusion. Dialectic proceeds from premises which are accepted on a lesser basis ‘by everyone or by the majority or by the wise, i.e. by all, or by the majority, or by the most notable and reputable of them’, and proceeds deductively from them to further conclusions.

There is an interpretation of Parmenides’poem which has not yet had, but deserves, a hearing. It reconciles two of the most prominent views of the meaning of the verb ‘to be’ as it occurs in the poem. It agrees with the spirit of those who interpret ‘εἷναι’ as‘existence.’ It agrees with the letter of those who interpret ‘εἷν αι’ as the copula.

En el presente artículo se sostiene que la filosofía práctica de Aristóteles puede dar lugar a dos sentidos distintos de προαίρεσις, los cuales se encuentran relacionados a su vez con dos sentidos distintos de deliberación. El primer sentido de προαίρεσις hace referencia a las elecciones deliberadas particulares, en las que el fin que se busca alcanzar, el deseo relacionado y los medios empleados son de carácter particular y se encuentran circunscritos a la situación concreta en que se realiza la elección. (...) En cambio, el segundo sentido de προαίρεσις se refiere a las elecciones vinculadas con objetivos de mediano y largo plazo, que si bien pueden ser particulares, buscan fines que trascienden la particularidad de la situación dada. Al primer tipo de προαίρεσις le corresponde la "deliberación descendente", mientras que al segundo le corresponde la "deliberación ascendente". Finalmente se presenta un análisis de las características del silogismo práctico de acuerdo a los dos tipos de deliberación. (shrink)

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.

There is a problem about belief and knowledge in Plato's epistemology that has exercised serious students of Plato only to settle into a recent orthodoxy. Guthrie characterizes the problem and its current resolution this way: ‘In the Meno doxa appeared to be a dim apprehension of the same objects of which knowledge is a clear and complete understanding … in the Republic each is directed to different objects, knowledge to the Forms and doxa to the sensible world alone … at (...) least the opinion seems now to prevail that on the relationship between doxa and knowledge Meno and Republic are irreconcilable, and exhibit a complete change of mind on Plato's part.'.
