The systems perspective, as applied to biology, involves regarding organisms as systems consisting of biological molecules in motion; its goal is to determine which interacting molecules make up the organism and how their interactions change over time. I argue here that Nicanor Austriaco’s attempt at reformulating Aristotelian-Thomistic hylomorphism in terms of the systems perspective fails because it looks to systems biology to answer questions that only natural philosophy can answer. These questions include whether an organism is collection of parts having accidental unity or is a substance, what constitutes an emergent property, and what role the final cause plays in understanding organisms. In addition, insufficient attention is paid to the Aristotelian-Thomistic tenet that the soul can only be united to a suitably disposed body, namely, one with organs. Nothing is offered to show that this tenet can be accorded with a perspective that views organisms as networks of interacting molecules.

In “Defending Adam After Darwin,” Nicanor Austriaco, OP, mounts a noteworthy defense of monogenism, part of which turns on the relationship between abstract thought and language. At a certain point, he turns to a passage from Aquinas’s Commentary on John to support two claims which he affirms without qualification: namely, that the capacity for forming abstract concepts corresponding to the quiddities of things presupposes the capacity for language and that we grasp concepts through words. In addition, he asserts that Aquinas is talking about abstraction in this passage. I argue that these three claims are based on a misreading of Aquinas. I then show that Aquinas would agree with the qualified claim that the formation of certain concepts presupposes the usage of words. I also show that Aquinas might accept with qualification the notion that the capacity for forming abstract concepts presupposes the capacity for language: namely, by way of disposition.

A correct understanding of experience is crucial for understanding the difference between human and non-human animals. Richard Sorabji interprets Aristotle to be affirming that experience in non-human animals is the same thing as a rudimentary universal, and that the individual who possesses experience achieves his goal by the application of low level univer-sals. I argue that this is neither a correct understanding of Aristotle’s statements in the Posterior Analytics, Metaphysics, and Nicomachean Ethics, nor is it true to the facts. Sorabji is misled, first, by the fact that experience can be regarded as a rudimentary universal in humans, and secondly by the fact that people of experience often possess universals that pertain to their actions. As to the latter, I show that people of experience do not succeed in virtue of possessing universals. As to the former, I point out that regarding experience as a rudimentary universal presupposes that the being that possesses them goes on to acquire true universals, something Sorabji fails to show. The presence of a modicum of experience in some non-human animals, thus, does not show that these beings share with us the capacity for knowledge of universals.

Aristotle maintains that paideia enables one to judge the method used by a given speaker without judging the conclusions drawn as well. He contends that this "paideia of principles" requires three things: seeing that principles are not derived from one another; seeing that there is nothing before them within reason; and, seeing that they are the source of much knowledge. In order to grasp these principles, one must respectively learn to recognize what distinguishes the subject matters studied in different disciplines, see first principles as coming from experience and acquire the habit of seeking them in one’s experience and, finally, see first principles as being the source of conclusions. While the second and third points might at first seem to pertain to "nous" and science, respectively, rather than to paideia, the case can be made that paideia involves more of a firm grasp of principles than "nous" and a less perfect way of relating conclusion to principles than science.

I examine the views of the renowned Catholic environmentalist, Thomas Berry, C.P., by comparing them with those of Thomas Aquinas, an author Berry frequently references. I intend to show that while the two share a number of views in common, ultimately the two diverge on many foundational issues, resulting in differing conclusions as to how we should regard and treat the environment. Aquinas upholds divine transcendence, whereas Berry regards the notion of divine transcendence to lead to the exploitation of creation and locates the divine in the universe itself. Berry accordingly thinks that we should revere all natural things, whereas Aquinas thinks we should revere God and creatures in God’s image. Aquinas maintains that the human soul is created by God and is in God’s image. He sees our rational soul as placing us above other natural things, and from it follows our responsibility to care for nature. Berry, to the contrary, sees this affirmation of discontinuity between humans and the rest of nature to be the root of our environmental woes, as providing a justification for human exploitation of nature. For Berry, humans have no special status, but are one member alongside others in the earth community. Rather than being created by God, “humans have nothing but what they receive from the universe.” By highlighting both the similarities and differences between these authors, I hope to contribute to the project of formulating a sound environmental ethics.

I argue that Edward Feser misconstrues the Aristotelian-Thomistic tradition on issues relevant to the arguments for God’s existence that proceed from finality in nature because he misapplies the A-T view that ordering to an end is inherent in natural things: (1) Feser speaks as if human action in no way serves as a model for understanding action for an end in nature; (2) he misreads, and ultimately undermines, the Fifth Way, by substituting intrinsic end-directedness in place of end-directedness; (3) he overlooks striking similarities between Paley’s argument from design and the Fifth Way. He also fails to consider the role of the good in the Fifth Way.

I investigate Aquinas’s position that natural virtue can pose dangers to living a moral life, dangers that include natural virtue’s inflexibility to circumstance, the opposing vices it may breed if blindly followed, and its aptitude for deceiving people into thinking they are genuinely virtuous. I also consider whether Aquinas regards these problems as remediable given that he sees natural virtue and natural vice as instances of nature being determined to one. He maintains that we can overcome the moral pitfalls that natural virtue and natural vice pose, though perfect mastery is not possible without divine intervention, insofar as our bodily disposition is not directly subject to reason.

If Aquinas lived today, he would accept that Darwin was correct, at leastas to the broad lines of his theory, namely, that the unfit are differentially eliminatedand chance is involved in the origin of new species. Aquinas in fact offered a similarexplanation for what he believed were spontaneously generated organisms. I intendto show that extending this sort of explanation to all species in no way affects thekey steps in the Fifth Way (e.g., “those things which lack cognition do not tendto an end unless directed by someone knowing and intelligent”). Thomas himselfprovides us with the crucial points for bringing evolution by natural selectioninto accord with the Fifth Way, including the distinction between a maker anda designer (builder vs. architect), an explanation for organisms’ imperfections interms of material necessity and secondary causality, and an account of the role ofchance in the world.

Environmentalists commonly offer three motives for why human populations need to be reduced or stabilized. One group maintains that human numbers threaten natural goods that should be preserved: biodiversity and ecosystems. A more extreme group maintains that we are taking up more than our fair share of the planet, eliminating species that have just as much right to be here. A third group advocates controlling human populations in order to prevent the environment from being degraded to the point that it harms people. I intend to examine in light of Catholic social teaching whether these proposed motives for controlling population are always anti-life.

Contrary to Michael Miller, I maintain that Descartes’s language test adequately distinguishes humans from non-human animals, and that the bonobosKanzi and Panbanisha have not passed it. Miller accepts Descartes’s language test as a good test for true language usage, but denies that it is an adequate test for the presence or absence of reason. I argue that it is a good test for reason, for normal rational beings eventually recognize the desirableness of knowledge of the world for its own sake as well as the fact that such knowledge can be increased by conversing with others. I also argue that the tests administered to the bonobos in question are inadequate for determining true language usage, as they could be passed by animals merely capable of associative learning.

Probably most of us have suffered at the hands of a friend who continually turned to us for help, as well having been grieved by a friend who failed to do so on a given occasion. And we have probably been chagrinned by friends who divulge to us only the most limited knowledge about their past problems, as well as by friends who provide unnecessary information about their woeful past. The purpose of this paper is to set out Aquinas’s recommendations for the moral guidelines to be followed in deciding which problems we disclose to our friends; these guidelines include: (1) not placing burdens on friends unnecessarily; (2) affording one’s friends the opportunity to do one good; (3) living in accord with one’s social nature; (4) being genuine; (5) encouraging friends struggling with moral problems; (6) bearing faith witness on occasion; (7) avoiding scandal; and (8) avoiding vices involving speech.
