 Stephanie Leary has offered an ingenious proposal within the essentialist framework: she posits a class of “hybrid” properties, whose essences entail (i) that they are instantiated just in case certain base properties are instantiated, and (ii) that ethical properties are instantiated whenever they are instantiated, and argues that these relations do not suffice for essentialist reduction of the ethical (Leary 2017; for critical discussion see Faraci 2017 and Toppinen 2018).
