Has anyone ever wondered which philosopher each of the mane six was like? Perhaps Pinkie Pie would benefit from Mill's Eudaimonic Utilitarianism, maybe Rarity would approve more of Aristotle's continuing advancement towards perfection, Twilight Sparkle may approve more strongly of Hume's atheist skepticism, Fluttershy might like the idea of Singer's animal rights activism, Applejack may like Descartes' need to understand what is true and what is not and Rainbow Dash may think that all philosophy is stupid and more time should be spent on doing real things rather than just thinking about them (like Gallileo).
Now, imagine what would happen if these six decided to enter into a philosophical debate...
