In my previous discussion of Christine Korsgaard’s prologue to The Sources of Normativity, I left out one significant feature of the story she tells of Western philosophy. This is the reason – related to the basic account of excellence of obligation – why Christianity proved philosophically more powerful than Greek thought.

On Korsgaard’s account of Greek metaphysics (à la Plato and Aristotle), goodness is a feature of reality, one more fundamental in a sense than the particular physical objects that appear before us. Perfect form is more real than imperfect matter. This is true whether, with Plato, those forms exist in a world apart from matter, or, with Aristotle, they exist within matter as its potential and telos.

But if that’s the case, Korsgaard notes, then the logical question is: why aren’t things perfect already? We normally think of theodicy – the problem of suffering and responses to it – as primarily a problem for Abrahamic traditions. If God is omnipotent and omnibenevolent, it’s hard to see how there can be suffering in the world (though it’s less hard to see how there can be evil). But broaden the question a bit – make it “the problem of bad” – and it appears elsewhere too. For Śaṅkara’s Advaita Vedānta, in which reality is pure knowledge, it’s a conundrum to think how there can be so much ignorance.

And Korsgaard seems to provocatively suggest that the Christians were better equipped to handle the problem than the Greeks – connecting to her account of how an ethics of excellence was superseded by an ethics of obligation. Continue reading →
