As noted in the aside on our current national religion, unauthenticity involves all the characteristics of authenticity, but in a biased selective fashion.
Unauthenticity involves selective attention, selective intelligence, selective rationality, selective responsibility and selective affection.
What is being selected? The “surd” of “absurdity”.
The surd seems to be going somewhere, but it is only digesting itself.
Authenticity does not give directionality to the surd. Authenticity simply does not feed it. It does so by giving directionality to the soul. One of the meanings of the prefix “ab” is “to”. Authenticity is the opposite of absurd.
