"Aesthetic choice is a highly individual matter, and aesthetic experience is always a private one. Every new aesthetic reality makes one's experience even more private; and this kind of privacy, assuming at times the guise of literary (or some other) taste, can in itself turn out to be, if not as guarantee, then a form of defense against enslavement. For a man with taste, particularly literary taste, is less susceptible to the refrains and the rhythmical incantations peculiar to any version of political demagogy. The point is not so much that virtue does not constitute a guarantee for producing a masterpiece, as that evil, especially political evil, is always a bad stylist. The more substantial an individual's aesthetic experience is, the sounder his taste, the sharper his moral focus, the freer - though not necessarily the happier - he is."
