"To equate the negation of negation with positivity is the quintessence of identification; it is the formal principle in its purest form. What thus wins out in the inmost core of dialectics is the anti-dialectical principle: that traditional logic which, more arithmetico, takes minus times minus for a plus. It was borrowed from that very mathematics to which Hegel reacts so idiosyncratically elsewhere."
Adorno, Negative Dialectics.
Chapeau, Teddy. Not bad at all.
