 Other varieties of metaethical constructivism are emerging, building upon the insights of philosophers other than Kant: the Spinozian variety (Zuck 2015), the Smithian variety (Stueber 2016), the Hegelian variety (Westphal 2013; Rockmore 2016; Laitinen 2016, and the Nietzschean variety (Katsafanas 2013; Silk 2015). Not all of them claim a place in metaethics, independently of existing forms of realism and antirealism. But they all find that the notion of construction is a distinctive explanatory device for capturing the objectivity and normativity of ethical truths.
