On Habermas

“Unlike Kant, Habermas is a thinker of late modernity; he no longer subscribes to the lofty belief in philosophy as the ‘queen of the sciences.’ Instead, as a critical theorist in the tradition of his teachers, he embraces a conception of ‘post-metaphysical thinking’ that sustains an alliance with the rest of the human sciences and remains responsive to its own social-historical context. Although genuinely metaphysical knowledge is no longer the rightful province of philosophical speculation, Habermas still cleaves in his own way to what Adorno once called ‘metaphysics at the moment of its fall.’ In our capacity for rational communication and in our appeal to a morality that leaves no one behind, there lies (in Habermas’s phrase) ‘a moment of unconditionality.’ While it lacks the prestige of a metaphysical absolute, it still bears a trace of the older idealism. Habermas calls it ‘an absolute that has become fluid as a critical procedure.’ Mundane reason, in other words, isn’t wholly mundane: In its modest commitment to rational argumentation, it keeps alive the universalizing impulse of the monotheistic religions when it strives to break free of its own conditions and ‘points beyond all particular forms of life.’”
