According to certain interpretations of quantum mechanics, the behavior of some physical systems is random—that is, certain current states of physical systems are related to other current states and the set of possible future states in a probabilistic, rather than a deterministic, fashion. This account of physical systems seems to conflict with the claim that there is an omnipotent God—that is, a God Who can efficaciously bring about any logically possible creaturely state, and Who can cause efficacious secondary causes—and so raises problems for classical theism. After explaining these problems, I provide a solution to them based upon a version of hylomorphism, which I call Theistic Hylomorphism with Randomness. On this view, it can be affirmed that the physical world is both random and in determinate states, and divine omnipotence can be upheld in a random world. After presenting this version of hylomorphism and showing how it defeats the problems for classical theism raised by quantum mechanics, I defend it against three objections.

Thomistic hylomorphism holds that human persons are composed of matter and a form that is also a subsistent entity. Some object that nothing can be both a form and a subsistent entity, and some proponents of Thomistic hylomorphism respond that our experience, as described by phenomenology, provides us with evidence that this theory is true. Some might object that that would be more easily seen to be a good way to defend Thomistic hylomorphism if the scholastics themselves had provided such evidence. I show how some scholastics do give evidence for Thomistic hylomorphism from their descriptions of our experience of forming and using habits. I consider their account of experiences of different acts of habit formation and exercise, and of experiences founded upon different kinds of potencies and obedience to reason that underlie their habits. Then I show that these experiences, when reasoned about in an effect to cause manner, provide evidence for Thomistic hylomorphism, and that the objection fails.

Francisco Suárez’s account of the transcendentals in Disputationes Metaphysicae 3 has been noted by Aertsen, Courtine, Darge, and Sanz for its reductionism; Suárez argues that all proposed transcendentals reduce to unum, verum, and bonum. This scholarship overlooks a key feature of Suárez’s account. In addition to providing his own theory, Suárez also works out a meta-metaphysical framework with which it can be shown how any proposed metaphysical item, including those that do not fit into Suárez’s own theory, relates to Being; he also works out rules for ordering these items. The way in which Suárez orders and reduces items related to Being involves several different kinds of reduction, and is more complex than current interpretations allow. Suárez’s framework and rules providea neutral standard for assessing the truth of any theory of transcendentals; this is shown through examining four accounts of the proposed transcendental aliquid using Suárez’s framework and rules

Many personalists have argued that an adequate account of the human person must include an account of subjectivity as irreducible to anything objectively definable. The personalists contend that Aristotle lacks such an account and claim that he fails to meet three criteria that a theory of the human person must fulfill in order to have an account of subjectivity as irreducible. I show first that some later Aristotelians fulfill these criteria, and then that Aristotle himself also does so. He describes four characteristics of human subjectivity that are considered crucial by many personalists. I do this through an interpretation of Aristotle’s accounts of substantial actualities, nous, friendship, and beauty.

Human ability to freely choose requires knowledge of human nature and the final end of man. For Aristotle, this end is happiness or full flourishing, whichinvolves various virtues. Modern scholarship has led to debate over which virtues are absolutely necessary. Taking into account the hierarchical nature of the soul and the fact that relationships with the divine and with others are necessary for human flourishing, it can be seen that human flourishing requires contemplation, phronesis and all the moral virtues, as perfections of the various parts of the soul. The truly happy person has actualized all of his faculties and potential relationships. Rather than taking one of the standard exclusivist or inclusivist viewpoints on this ‘problem of the two lives,’ this paper argues that a holistic reading of Aristotle’s ethical works requires a hierarchical and relational view of the virtues, with all of them necessary for human flourishing.

In this paper we present the standard Thomistic view concerning substances and their parts. We then note some objections to that view. Afterwards, we present Aquinas’s Christology, then draw an analogy between the relation that holds between the Second Person and the assumed human nature, on the one hand, and the relation that holds between a substance whole and its substance parts, on the other. We then show how the analogy, which St. Thomas himself drew at points, is useful for providing a theory that answers the objections that the standard Thomistic view faces. Finally we answer objections to our approach. We conclude that there is a hylomorphic theory, founded on an analogy from Aquinas’s Christology, that fits well with the empirical data concerning substance parts, on which some complete created material substances have other complete created material substances as parts.
