Plato criticizes Homer’s effort to promote religious skepticism through his portrayal of the gods for overestimating the power of human reason and underestimating the power of human passions, and he criticizes Homer’s education concerning human excellence for inadvertently glamorizing the passionate and tragic hero Achilles and all too effectively hiding his own example as a philosophic thinker behind the mask of the divinely inspired singer. Plato therefore replaces the Homeric education with a new, poetic, Platonic education that presents Socrates – the fearless, dispassionate, self-sufficient, apolitical philosopher who promulgates the pious, edifying, and reassuring doctrines of the separate Forms and the Immortality of the Soul – as an explicit object of admiration and model for imitation.

Homer plays an important but overlooked role in the history of political philosophy. Plato criticizes the philosophic tradition founded by Homer and establishes a new one in its place; Machiavelli and Nietzsche, two leading philosophic critics of Plato, invoke Homer in their arguments against Plato and his legacy.

Homer first presents as a model of human excellence the hero Achilles, who lives a life of political and military virtue to the fullest, who becomes painfully aware of the limits of that way of life, and whose example as a tragic, suffering, questioning hero points to the contemplative singer Homer as the true model of human excellence in the Homeric poems. Through his explicit, skeptical judgments concerning gods and heroes; his scientific but compassionate accounts of death; and his similes, Homer points to himself as a philosophic thinker, but he deliberately hides his philosophic life in the poems to avoid incurring popular hostility and to encourage the most thoughtful members of his audience to discover the independent-minded life of philosophy on their own and for themselves.

Plato identifies Homer as the philosophic educator of Greece but severely criticizes the Homeric education for his portrayal of the gods, his portrayal of heroes as exemplars of human excellence, and his portrayal of himself. Homer reveals through his poems that nature limits the power of the gods and that the gods’ own immortal nature renders them incapable of understanding and caring for humans and hence incapable of providing for them.
