Good reasons to philosophize: On Hadot, Cooper, and ancient philosophical protreptic

Abstract

This paper reassesses the Cooper-Hadot debate surrounding how students are converted to philosophy as a way of life (section 1) through engagement with philosophical protreptics. In section 2, the paper identifies the core “argument from finality” in philosophical protreptics seeking to convert non-philosophers to philosophy, starting from the universal human interest in securing eudaimonia. In line with Cooper, this argument seeks to persuade prospective students on rational grounds, so that their choice to philosophise would be rationally motivated. In section 3.1, the paper illustrates how in Plato's Euthydemus (a) the choice to undertake philosophy is rationally justified by Socrates, using the eudaimonistic argument from finality. In section 3.2, by recourse to Aristotle's Protrepticus, the paper shows how the protreptic texts also compared philosophy to other intellectual pursuits, notably rhetoric, so as to recommend philosophy specifically for delivering a directive wisdom concerning how to live.
