Abstract
The Kantian strain of practical constructivism (through Rawls, Korsgaard, and others) has been so influential that it is tempting to identify the constructivist approach in practical domains with the Kantian development of the outlook. In this essay, I explore a different variety of practical constructivism, what I call “Aristotelian constructivism”. My aim is to establish conceptual space for this form of constructivism by indicating in what ways Aristotelian constructivism agrees with its Kantian counterparts and in what ways it differs. I claim that it is, in one sense, more faithful to the constructivist enterprise than the Kantian varieties, in that its understanding of both the establishment of practical truth and the vindication of the theory itself is constructivist.
