 Recent debates about constructivism focus on its “constitutivist strategy”, which explains the normativity of (practical or moral) reasons in terms of what is constitutive of agency. For instance, Korsgaard (2009) argues that the principles governing action are “constitutive standards” of agency, that is, standards arising from the nature of agency itself. The marks of agency are autonomy and efficacy, and the categorical and hypothetical imperatives are norms grounded on these two properties. These norms are “constitutive” of agency in that (i) they determine what an agent is (“constitution requirement”), (ii) an agent makes herself into an agent, and into the particular agent who she is, by conforming to those standards (“self-constitution requirement”). According to Korsgaard (2019), Kantian constructivism is uniquely positioned to vindicate the self-constitution requirement while Humean and Aristotelian theories fail to meet it. But there is a disagreement about whether constitutivism is compatible with Kant’s ethics. While some scholar hold that the constitutivist strategy is a distinctively Kantian move in response to moral skepticism (O’Neill 1989, Korsgaard 2019, Engstrom 2009, Bagnoli 2019, Shafer 2019), others hold that it does not serve the Kantian agenda (Gobsch 2019, Saemi 2016, Tenenbaum 2016).
