If we call some theory T, call the aims that it gives us our T-given aims. Call T indirectly individually self-defeating when it is true that, if someone tries to achieve his T-given aims, these aims will be, on the whole, worse achieved.are in MacIntyre's analogy, like the empty chanting of the priests in A Canticle for Leibowitz, blindly trying to recreate science based on rituals they don't understand. For MacIntyre, moral virtue - all virtues - are inseparably embedded in the lived experience of human culture, and part of our basic understanding of and interaction with the world. In metaethical terms this is probably akin to subjectivism, or (in Isaiah Berlin's term) value pluralism. It is close to my worldview, and, I suspect, close to that of Parfit's hero Bernard Williams.
Suppose that Satan rules the Universe. Satan cannot affect which is the true theory about rationality, or which is the best or best justified theory. But he knows which this theory is, and he perversely causes belief in this theory to have bad effects in this theory’s own terms.Another especially egregious one involves scientists replacing every cell in my brain and body, one by one, with those of 30-year-old Greta Garbo. (A lot of modern philosophy is the Sorites paradox in disguise.) This is dumb in a specific way - even an exact replica of Greta Garbo, being not "Greta Garbo" but "an existing being replaced cell by cell with Greta Garbo in a lab", would dramatically diverge from Greta Garbo within the first second of awakening - but also in a broader sense, that such an operation is so bizarrely improbable, such a cartoonish reduction of the little we know of neuroscience, that to waste even a second of our short time on Earth considering it feels obscene. (Needless to say, if such an operation becomes available in the future I will need to dramatically revise many of my philosophical beliefs.)
