There is a danger in being unpretentious because it is not always a synonym of honest or unconscious; indeed, I fear that unpretentious is often a synonym to pretentious. Neither term means more than a type of façade; they are both the putting on of airs. The one turns up its nose at the general crowd, and the other, adding the prefix, turns its nose up at those perceived to be turning up the nose. A ruffian acting more ruffly to shock someone more genteel is just as pretentious as a well-mannered socialite snubbing someone for using the wrong fork.
Yet there is a difference, a terrible Hell, the unpretentious are in danger of from which the mere pretentious are as innocent as lambs. The unpretentious, as I am using the word, may hate something that is actually good. The pretentious oversteps the ordinate. It is better to dress smartly, to speak well, to sit right, to be mannered. The pretentious attitude, coming from pride, is a perversion of something good. We ought to have standards of behavior, and we really ought to enforce those standards through social pressure. However that becomes a pretense, however those symbols and behaviors we use to point to something higher become disordered and idolatrous, the unpretentious are inherently rebels, and as far as the symbols still retain their symbolism, the unpretentious are in the very dangerous position of calling good evil and evil good.
They are both forms of hypocrisy, but as the pretentious puts forth good standards, or even just affirms the standard that one ought to hold to standards, the unpretentious erects standards that are purposely bad, or worse, bites his own tail, generating standards against standards. I can talk with the first type of hypocrite and hold him to his own standards, I can argue with the second hypocrite that his standards are bad, but this third hypocrite, the ouroboros, I do not know how to reach. This last hypocrite is perhaps not a hypocrite at all; the hypocrite wears a mask over his true self, but the ouroboros devours himself leaving only the mask.
