In this paper, I defend Peter Geach’s theory of Relative Identity against the charge that it cannot make sense of basic semantic notions.

In this paper, I consider the philosophical consequences of one tradition in Trinitarian theology, which emphasizes that each of the persons of the Trinity is wholly God. I pay special attention to Leftow’s claim that the persons of the Godhead must be divine in the same sense of the word ‘divine’ as the Godhead itself. I argue that the existing philosophical account of the Trinity which best captures this view is what I have termed the ‘Strong Theory of Relative Identity,’ (...) first proposed Peter Geach. I then develop what I take to be the most pressing objection to this account of the Trinity, namely that it cannot be supplemented with a coherent model-theoretic semantics. I end with a suggestion for responding to this objection. (shrink)

In this article I present St. Thomas Aquinas’s views on the possibility of multiple incarnations. First I disambiguate four things one might mean when saying that multiple incarnations are possible. Then I provide and justify what I take to be Aquinas’s answers to these questions, showing the intricacies of his argumentation and concluding that he holds an extremely robust view of the possibility of multiple incarnations. According to Aquinas, I argue, there could be three simultaneously existing concrete rational natures, each (...) of which is assumed by all three of the Divine Persons, all at the same time.

A paradox adapted from the well-known 'paradox of increase ' has been formulated against composite Christology in recent literature. I argue that concrete -composite Christologists can reply by denying the premise that the pre-incarnate divine nature = the Second Person of the Trinity. This denial can be made by modifying a hylomorphic theory of individuals. Using an analogy from material coinciding objects, this modified theory provides an illuminating account of how a person can gain parts over time but remain numerically (...) identical, and it demonstrates that concrete nature and person are not the same thing.

The notion that Jesus Christ is one person with two natures has been the venue of much philosophical theological work in the past 40 years. One mode of engagement with this idea has been to defend the coherence of the idea. This has been done by, for example, revising standard conceptions of divinity and humanity or predicate attribution. Another mode of engagement with the doctrine is to offer models for how the state of affairs of the Incarnation might work. This (...) could involve retrieving models from thinkers of the past. Finally, the constructive mode applies the reasoning of the two natures/one person conception to other areas of Christian theology such as the atonement or the Eucharist. Examples of each of these modes from the contemporary analytic literature are presented. (shrink)

In this paper we investigate composition models of incarnation, according to which Christ is a compound of qualitatively and numerically different constituents. We focus on three-part models, according to which Christ is composed of a divine mind, a human mind, and a human body. We consider four possible relational structures that the three components could form. We argue that a ’hierarchy of natures’ model, in which the human mind and body are united to each other in the normal way, and (...) in which they are jointly related to the divine mind by the relation of coaction, is the most metaphysically plausible model. Finally, we consider the problem of how Christ can be a single person even when his components may be considered persons. We argue that an Aristotelian metaphysics, according to which identity is a matter of function, offers a plausible solution: Christ’s components may acquire a radically new identity through being parts of the whole, which enables them to be reidentified as p.

In this article I object to Le Poidevin's contention that relative identity is beset with an infinite metaphysical regress. I argue, first, that since Le Poidevin's regress argument presupposes a direct theory of reference, it does not apply to accounts of relative identity which reject this account of reference. I argue, second, that Le Poidevin's regress is not inevitable for one who accepts a direct account of reference, since it does not apply to the formal logic of relative identity which (...) van Inwagen uses to articulate and defend the mysteries of the Trinity and the Incarnation.
