Constituent ontologies maintain that the properties of an object are either parts or something very much like parts of that object. Recently, such a view has been criticized as leading to a bizarre and problematic form of substance dualism and implying the existence of impossible objects. After briefly presenting constituent and relational ontologies, I respond to both objections, arguing that constituent ontology does not yield either of these two consequences and so is not shown to be an unacceptable ontological framework.

Several philosophers have argued that property dualism and substance materialism are incompatible positions. Recently, Susan Schneider has provided a novel version of such an argument, claiming that the incompatibility will be evident once we examine some underlying metaphysical issues. She purports to show that on any account of substance and property-possession, substance materialism and property dualism turn out incompatible. In this paper, I argue that Schneider’s case for incompatibility between these two positions fails. After briefly laying out her case for incompatibility, I present an account of substance—one that relies on a relational ontology—that makes the combination of substance materialism and property dualism unproblematic. Then I show that even under the theories of substance that Schneider considers—those that rely on a constituent ontology—there still is no incompatibility problem

Joseph Keim Campbell has attempted to say “farewell” to a particular version of source incompatibilism, viz. direct source incompatibilism, arguing that direct source incompatibilism is committed to two theses that are in tension, thereby threatening the coherence of the position. He states that direct source incompatibilism is committed to the following claims: SI-F: there are genuine Frankfurt-style counterexamples. SI-D: there is a sound version of the Direct Argument. Campbell argues that both of these theses cannot be simultaneously held since a sound version of the Direct Argument would undermine Frankfurt-style counterexamples, and vice versa. After laying out Campbell’s argument, I will first make some preliminary comments regarding actual direct source incompatibilists and their commitment to SI-F and SI-D. I then object to Campbell’s argument, arguing that one can accept both SI-F and SI-D, thereby vindicating direct source incompatibilism from the charge of incoherence.

Standard animalists are committed to a stringent form of restricted composition, thereby denying the existence of brains, hands, and other proper parts of an organism . One reason for positing this near-nihilistic ontology comes from various challenges to animalism such as the Thinking Parts Argument, the Unity Argument, and the Argument from the Problem of the Many. In this paper, I show that these putatively distinct arguments are all instances of a more general problem, which I call the ‘Too Many Candidates Problem’ . Given my formulation of the problem, it is evident that standard animalists are mistaken in believing that restricting composition is the only solution. I show that there is another option for solving the TMC. The advantage of such a position, which I call ‘unrestricted animalism’, is that it is compatible with unrestricted composition and the existence of brains and other proper parts of an organism. I conclude by sketching several strategies one can take regarding this latter solution to the TMC
