A study of Homer in conjunction with Plato, Machiavelli, and Nietzsche confirms that Homer was a philosophic thinker and that he plays an illuminating role in the thought of each of the three political philosophers. This study also shows that there are many ways of living a philosophic life; that philosophers may present themselves in different guises depending on the political, religious, and intellectual circumstances they may find themselves in; that their most fundamental choice is whether or not to present themselves explicitly as philosophers; and that therefore we must broaden our understanding of who a philosopher is beyond those who explicitly present themselves as philosophers and consider the possibility that a number of poets, statesmen, historians, and even theologians of the past may also be philosophers in their own right.

Nietzsche criticizes Plato for having praised the philosophic life in such a way as to deprive the active political and military life of the honor and vitality it enjoyed in the Greek culture founded by Homer and therefore seems to call for a reversal of the moral and political legacy of Platonism and Christianity and a revival of Homeric culture. But Nietzsche ultimately criticizes Plato more seriously, not for explicitly celebrating the philosophic life as the best way of life for a human being, but rather for presenting the philosopher as a champion of morality and religion and thereby obscuring the skeptical nature of the philosopher and he therefore seeks, through his rhetorical presentation of philosophy as emphatically opposed to morality and religion, to reintroduce the radical moral and religious skepticism of philosophy to a world that has lost sight of it.
