Adorno the Clean-Shaven on the Beard

Theodor W. Adorno, Negative Dialectics, p. 123:

The beard is the oppositionist costume of juveniles acting like cavemen who refuse to play along with the cultural swindle, while in fact they merely don the old-fashioned emblem of the patriarchal dignity of their grandfathers.

It seems fair to observe, however, that Adorno and the men of his generation were just as oppositionist in refusing to sport the beards that graced the jowls of their fathers.
