Second, bodily pleasures can be contrary to reason, particularly those that are enjoyed in excess. Among the philosophical disciplines, metaphysics is the most difficult and presupposes competence in other philosophical disciplines such as physics (as it is practiced, for example, in Aristotles Physics, that is, what we might call philosophical physics, that is, reflections on the nature of change, matter, motion, and time). In order to do this, we have to examine the various powers that human beings possess, since, for Thomas, mature human beings possess various powers, and virtues in human beings are perfections of the characteristically human powers (see, for example, ST IaIIae. Without prudence, human action may be good but not virtuous since virtuous activity is a function of rational choice about what to do in a given set of circumstances; although, as we shall see, virtuous action arises from a virtuous habit, and virtuous action is not habitual in the sense that we do it without even thinking about it.. q. People do not typically argue their way to believing the general norms of morality, for example, it is wrong to murder, one should not lie. It is not the case that there are no intermediate causes and no effect E [from (1)]. 4). 154, a. q. 55, a. Therefore, God does not change (see, for example, ST Ia. . By contrast, when we use a word equivocally, two things (x and y) are given one and the same name n, where n has one meaning when predicated of x and a different meaning when predicated of y. St. Thomas Aquinas' Five Proofs for God's Existence William Rowe's Argument from Evil John Hick's Soul-Making Theodicy Summary of J. L. Mackie's "Evil and Omnipotence" Summary of Paul Ricoeur's "Evil, A Challenge to Philosophy and Theology" Summary of Luc Bovens's "The Value of Hope" Summary of Pope Francis's "Dialogue and Friendship in Society" For Thomas, intellect and will always act in tandem. Although we cannot know the essence of God in this life, we can know that God exists as the absolutely first efficient cause of creatures, we can know what God is not, and, insofar as we know God as the absolutely first efficient cause of creatures and what God is not, we can know God by way of excellence. A typical and more charitable interpretation of premise (7) is that Thomas is talking here about concurrent efficient causes and their effects, for example, in a case where a singers song exists only as long as the singer sings that song. That being said, not all moral acts are equally morally wrong for Thomas. 64, a. q. Areas of Expertise Thomas Aquinas, Philosophy, Natural Law, Theoretical Ethics. For Thomas, following St. Augustine, some of the ideas of God are exemplar formal causes in this sense, for example, Gods idea of the universe in general, Gods idea of what-it-is-to-be a human being, and so forth, function, as it were, as plans or archetypes in the mind of the Creator for created substances. (1932; reprint, Eugene, OR: Wipf and Stock, 2004). 58, a. This set of moral laws that transcends the particularities of any given human culture is what Thomas and King call the natural law. Therefore, if God can change, then God is composed of substance and accidental forms. 54, a. For Thomas, the final cause is the cause of all causes (On the Principles of Nature, ch. However, it is not just intellectual pleasure that belongs to virtuous human action in this life for Thomas, but bodily pleasure, too. For example, when we say, John is wise, we do not mean to imply John is wisdom. 5, respondeo). This distinction between an ultimate end and the ultimate end is important and does not go unnoticed by Thomas. In other words, Thomas would also reject the following view: (M) Human beings are composed merely of matter. On the other hand, if we merely equivocate on wise when we speak of John and God, then it would not be possible to know anything about God, which, as Thomas points out, is against the views of both Aristotle and the Apostle Paul, that is, both reason and faith. Consider that Thomas thinks substantial forms fall into the following sort of hierarchy of perfection. For example, some quantity of prime matter m might be configured by the substantial form of an insect at t, be configured by the substantial forms of a collection of living cells at t+1 (for example, some moments after the insect has been eaten by a frog), be configured by the substantial forms of a collection of chemical compounds at t+2, and be incorporated into the body of a frog as an integral part of the frog such that it is configured by the frogs substantial form at t+3. 2, ad2). 3, which is an argument from motion, with Thomas complete presentation of the argument from motion in SCG, book I, chapter 13. Its a common scholarly myth that early modern philosophers (starting with Descartes) invented the idea of the human being as a self or subject. My book tries to dispel that myth, showing that like philosophers and neuroscientists today, medieval thinkers were just as curious about why the mind is so intimately familiar, and yet so inaccessible, to itself. SCG is thus Thomas longest and most ambitious attempt at doing what he is probably most famous forarguing philosophically for various theses concerning the existence of God, the nature of God, and the nature of creatures insofar as they are creatures of God. So for Aquinas, we dont encounter ourselves as isolated minds or selves, but rather always as agents interacting with our environment. ST is split into three parts. An excellent collection of scholarly introductions to all the major facets of Thomas thought. Of course, contemporary philosophers of science would not find sacred theologys inability to fit neatly into a well-defined univocal conception of science to be a problem for the scientific status of sacred theology. But the significance of those experienceswhat they are, what they tell me about myself and the nature of the mindrequires further experience and reasoning. For our purposes, let us focus on three pieces of negative theology in Thomas natural theology: that God is not composed of parts; that God is not changeable; that God does not exist in time. For example, think of the locutions, the cat is an animal and the dog is an animal. Here, the same word animal is predicated of two different things, but the meaning of animal is precisely the same in both instances. UNDERSTANDING THE SELF. We also know, when we reflect upon it, that failing to honor those who have given us extremely valuable gifts we cannot repay would be to do evil. Second, there are those universal principles of the natural law that, with just a bit of reflection, can be derived from the first principle of the natural law (ST IaIIae. Some human laws, Thomas thinks, will be different in different times and places, if only because they are enacted in times and places where there are different geographical, moral, political, and religious circumstances and needs. Thomas therefore distinguishes three different ways words are used: univocally, equivocally (in a sense that is complete or uncontrolled), and analogously, that is, equivocally but in a manner that is controlled. As we noted above, the knowledge that comes by prudence has the agents possession of the other moral virtues as a necessary condition, for the knowledge we are speaking of here is knowing just how to act courageously in this situation; to know this, one must have ones passions ordered such that, whatever one chooses to do, one knows one always ought to act courageously. q. 10). As Thomas puts it: Prudence is right reason of things to be done (ST IaIIae. Frogs, since they are by nature things that flourish by way of jumping and swimming, are composed of bone, blood, and flesh, as well as limbs that are good for jumping and swimming. The case where there is the clearest need to speak of a composition of essentia and esse is that of the angels. Learning about a things nature requires a long process of gathering evidence and drawing conclusions, and even then we may never fully understand it. In the view of Aquinas, philosophy is a science, which, unlike other sciences, receives its principles via God's revelation without borrowing principles or depending on the other sciences. Just as a bit of real knowledge of human beings is better for Susans soul than Susans knowing everything there is to know about carpenter ants, Susans possessing knowledge about God by faith is better for Susans soul than Susans knowing scientifically everything there is to know about the cosmos. 79, a. However, Thomas also thinks there are certain kinds of human actions that conduce to happiness. However, Thomas (like Aristotle) thinks of the final cause in a manner that is broader than what we typically mean by function. He has two ways of conceptualising the self as radically oriented to God, namely self-presentation and self-realisation. Like the first universal principles of the natural law, the truthfulness of these secondary universal precepts of the natural law is immediately obvious to uswhether we know this by the natural light of reason insofar as the truth of such propositions is obvious to us as soon as we understand the meaning of the terms in those propositions or we immediately know them to be true by the light of faith (see, for example, ST IaIIae. 64, Art.7). 2, a. 5, respondeo), one must not intentionally spill ones seed in the sex act (ST IIaIIae. Thus, we should not be surprised that Thomas thinks that a proper use of positive predications when it comes to God, for example, in the phrase, God is wise, involves predicating the term wise of God and human beings analogously and not univocally or equivocally (ST Ia. However, some ends are what Thomas calls ultimate. An ultimate end is an end of action such that a being is inclined to it merely for its own sake, not also as a means to some further end. q. Where many philosophers have been content to treat topics in meta-ethics and ethical theory, Thomas also devotes the largest part of his efforts in ST, for example, to articulate the nature and relations between the particular virtues and vices. q. In addition to his teaching duties, Thomas was also required, in accord with university standards of the time, to work on a commentary on Peter the Lombards Sentences. Thomas agrees with Aristotle that the attainment of happiness consists in the souls activity expressing virtue and, particularly, the best virtue of contemplation where the object of such contemplation is the best possible object, that is, God. 75, a. Although Thomas authored some works of pure philosophy, most of his philosophizing is found in the context of his doing Scriptural theology. q. First, we might distinguish the virtues according to certain general properties of the virtues: for instance, by saying that discretion belongs to prudence, rectitude to justice, moderation to temperance, and strength of mind to courage (ST IaIIae. q. We might think of Thomas position at Paris at this time as roughly equivalent to an advanced graduate student teaching a class of his or her own. As has been seen, perfect human happiness (qua possession) consists of the beatific vision. Therefore, if something does not change, it is not measured by time, that is, it does not exist in time. Our coming to know with certainty the truth of a proposition, Thomas thinks, potentially involves a number of different powers and operations, each of which is rightly considered a source of scientia. 3, respondeo). Thomas second reason that there would have been human authorities in the state of innocence has him drawing on positions he established in ST Ia. Augustine and Aquinas St. Augustine, bishop of Hippo, was one of the first notable Christian philosophers. Second, in order to ensure the king does not become a tyrant, the government (and its constitution) should be written so as to limit the power of the king (De regno, book I, ch. 6, respondeo). 1, ad1). Although virtuous actions are pleasant for Thomas, they are, more importantly, morally good as well. 3, ad1) Thomas says, insofar as it is concerned with things to be done. We might think that it is some sort of intellectual faculty that coordinates different sensations, but not all animals have reason. Both of them do not actually see, but not in the same sense. Saint Augustus and Aquinas are both renowned for their input in the field of philosophy and theology with Augustus coming some centuries before Aquinas. Thomas also thinks intelligent discussion of the subject matter of metaphysics requires that one recognize that being is said in many ways, that is, that there are a number of different but non-arbitrarily related meanings for being, for example, being as substance, quality, quantity, or relation, being qua actual, being qua potential, and so forth. Finally, the virtue of charity creates a union of friendship between the soul of its possessor and Goda union that is not natural to human beings but requires that God raise up the nature of its possessor to God. Although venial sin can lead to mortal sin, and so ought to be avoided, a venial sin does not destroy supernatural life in the human soul.) Since virtues are dispositions to make a good use of ones powers, Thomas distinguishes virtues perfecting the intellectcalled the intellectual virtuesfrom those that perfect the appetitive powers, that is, the moral virtues. Thomas composed four of these during his lifetime: his commentary on Peter Lombards Sentences, Summa contra gentiles, Compendium theologiae, and Summa theologiae. Thomas Aquinas. The material cause in this sense is the subject of changethat which explains how something can lose the property not-F and gain the property F. For example, the material cause for an accidental change is some substance. However, according to Thomas, it is also the case that one cannot be perfectly prudent unless one is also perfectly temperate, just, and courageous. However, we all know that our father and mother have given us extremely valuable gifts we cannot repay, for example, life and a moral education. Following Aristotle in Politics, book III, chapter 7, Thomas identifies three unjust forms of unmixed government that are opposed to these just forms: for example, tyranny, that is, rule by one man who looks after his own benefit rather than the common good, oligarchy, that is, rule by a few wealthy men who look after their own good rather than the common good, and democracy, rule by the many poor people for their own good rather than the common good (see, for example, De regno ad regem Cypri, I, ch. One applies a name substantially to x if that name refers to x in and of itself and not merely because of a relation that things other than x bear to x. Given that (as Thomas believes) human beings are not born with knowledge and virtue, it seems obvious that this would have been true in the case of the relation between parents and their children. However, even when it is separated from matter, a human soul remains the substantial form of a human being. However, justice, wisdom, goodness, mercy, power, and love are pure perfections. Therefore, the final cause of the knife is to cut; the final cause of the heart is to pump blood. Thus, the object of human happiness, whether perfect or imperfect, is the cause of all things, namely, God, for human beings desire to know all things and desire the perfect good. q. 6, a. q. However, prudence is essentially a perfection of intellect, and so it is an intellectual virtue. Virtue ethicists have traditionally been interested in defending a position on the logical relations between the human virtues. In order for x to perform the act of bringing x into existence at time t, x must already exist at t in order to perform such an act. 2], like a window in a house is that by which we see what is outside the house.) It is here that Thomas received his early education. Therefore, God does not exist in time. These particular practical applications of the natural law, as long as they meet the conditions of law, have the force of law. Rather, the truth of these norms is self-evident (per se nota) to us, that is, we understand such norms to be true as soon as we understand the terms in the propositions that correspond to such norms (see, for example, ST IaIIae. q. Thomas contends that God does not exist in time (see, for example, ST Ia. Aquinas, Thomas, in. First, there are the rational powers of intellect and will.
