Thomas thinks that the intellect has what he calls a passive power since human beings come to know things they did not know previously (see, for example, ST Ia. For example, consider the manner in which we use the word “good.” We sometimes speak of “good dogs,” and sometimes we say things such as “Doug is a good man.” The meanings of “good” in these two locutions obviously differ one from another since in the first sense no moral commendation is implied where there is moral commendation implied in the latter. 6, a. Human beings will then be restored to their natural state as embodied beings that know, will, and love. Other examples Thomas would give of tertiary precepts of the natural law are one ought to give alms to those in need (ST IIaIIae. St. Thomas Aquinas THE SUMMA THEOLOGICA Translated by Fathers of the English Dominican Province :Index. To continue with this example, Thomas thinks that God, too, is at work as the primary efficient cause of H’s coming into existence, since, for example, (a) God is the creating and conserving cause of (i) any sperm cell as long as it exists, (ii) any female gamete as long as it exists, and (iii) all aspects of the environment necessary for successful fertilization. For example, on Thomas’ reading, Maimonides thinks “God is good” should be understood simply as “God is not evil.” Thomas notes that other theologians take statements such as “God is good” to simply mean “God is the first efficient cause of creaturely goodness.” Thomas thinks there are a number of problems with these reductive theories of God-talk, but one problem that both of them share, he thinks, is that neither of them do justice to the intentions of people when they speak about God. Morally virtuous action, therefore, is minimally morally good action—morally good or neutral with respect to the kind of action, good in the circumstances, and well-motivated. Having the ability to be hit by an object is not an ability (or potentiality) Socrates has to F, but rather an ability (or potentiality) to have F done to him; hence, being able to be hit by an object is a passive potentiality of Socrates. In addition, there are three theological virtues, described as faith, hope and charity, which are supernatural and are distinct from other virtues in that their object is God. 4, obj. However, a perfect knowledge of the ends or principles of human action requires the possession of those virtues that perfect the irascible appetite, the concupiscible appetite, and the will, otherwise, one will have a less than perfect, that is, a distorted, picture of what ought to be pursued or avoided. The intellectual act of simple apprehension is simple in the sense that it does not yet imply a judgment on the part of an intellect about the truth or falsity of a proposition. q. In his lifetime, Thomas’ expert opinion on theological and philosophical topics was sought by many, including at different times a king, a pope, and a countess. 2). For Thomas, (M) is false since human beings, like all material substances, are composed of prime matter and substantial form, and forms are immaterial. 3), the second way. We can begin with the fact that, according to Thomas, morally good actions are moral rather than amoral. We might call this third of universal principle of the natural law the tertiary precepts of the natural law. 1, a. q. Thus, sexual pleasure must hinder reason insofar as it distracts us from using reason or weakens reason. However, infused virtues differ from human virtues in a number of interesting ways. He also refused out of hand such prestigious positions as Archbishop of Naples and Abbot of Monte Cassino (although he was persuaded back to the University of Naples in 1272). Of course, contemporary philosophers of science would not find sacred theology’s inability to fit neatly into a well-defined univocal conception of science to be a problem for the scientific status of sacred theology. In Thomas’ view, anything that is understood is understood in virtue of its form. Thomas began his theological studies at the University of Naples in the fall of 1239. Even more significant, thinks Thomas, is the fact that simple fishermen were transformed overnight into apostles, that is, eloquent and wise men. Premise (7) shows that Thomas is not in this argument offering an ultimate efficient causal explanation of what is sometimes called a per accidens series of efficient causes, that is, a series of efficient causes that stretches (perhaps infinitely) backward in time, for example, Rex the dog was efficiently caused by Lassie the dog, and Lassie the dog was efficiently cause by Fido the dog, and so forth. Second, we might distinguish the cardinal virtues as Thomas himself prefers to do, after the example of Aristotle, namely, insofar as the different virtues perfect different powers. Given his notion of science (whether taken as activity, demonstrative argument or intellectual virtue), we might think that Thomas understands the extension of science to be wider than what most of our contemporaries would allow. Where being is concerned, Thomas also distinguishes between beings in nature and intentional beings or beings of reason (see, for example, Commentary on Aristotle’s Metaphysics IV, lec. Thomas answers this question by saying, “In some senses, human beings would have been equal in the state of innocence, but in other senses, they would not have been equal.” Thomas thinks human beings would have been equal, that is, the same, in the state of innocence in two significant senses: (a) all human beings would have been free of defects in the soul, for example, all human beings would have been equal in the state of innocence insofar as none would have had sinned, and (b) all human beings would have been free of defects in the body, that is, no human beings would have experienced bodily pain, suffered disease, and so forth in the state of innocence. However, where there are many reasonable individuals, there will be many reasonable but irreconcilable ideas about how to proceed on a variety of different practical matters. 110, a. For example, a knife is something that tends to cut. However, the fact that law protects the weak from the strong is accidental to law for Thomas. 7 [ch. Ralph McInerny, Ethica Thomistica: The Moral Philosophy of Thomas Aquinas (Catholic University of America, 1997) Additional on-line information about Aquinas includes: Daniel J. Kennedy’s *extremely thorough treatment of Aquinas and treatise on his relation … Thus, some would have freely chosen to make a greater advance in knowledge in virtue than others. Since scientia for Thomas involves possessing arguments that are logically valid and whose premises are obviously true, one of the sources of scientia for Thomas is the intellect’s second act of intellect, composing and dividing, whereby the scientist forms true premises, or propositions, or judgments about reality. q. However, unless such knowledge is joined to knowledge of particular cases in the moral agent or there is a knowledge of particular moral principles in the agent, then the moral agent will not know what he or she ought to do in a particular circumstance. Thomas argues that in order to make sense of any genuine action in the universe we must distinguish its end or goal from the various means that a being employs in order to achieve such an end, for if a being does not act for an end, then that being’s acting in this or that way would be a matter of chance. St. Thomas Aquinas Philosophy 1. 1, aa. In addition, like other animals, human beings must move themselves (with the help of others) from merely potentially having certain perfections to actually having perfections that are characteristic of flourishing members of their species. The principle of causality is a piece of common sense that arguably also plays a pivotal role in all scientific inquiry. Thomas knows of some philosophers, for example, Moses Maimonides (1138-1204), who take positive predications with respect to God to be meaningful only insofar as they are interpreted simply as statements of negative theology. A diverse group of subsequent religious thinkers have looked to Thomas’ modeling the marriage of faith and reason as one of his most important contributions. 65, a.1, respondeo). The appearance of these editions, the first in 19l7 and the last in 1965, covers much of the scholarly life of their author. In addition, things that jump and swim must be composed of certain sorts of stuffs and certain sorts of organs. There is also an argument that Brian Davies (1992, p. 31) calls “the existence argument,” which can be found at, for example, ST Ia. q. In this sense of “matter,” the material cause of an axe is some iron and some wood. Therefore, we can apply positive predicates to God, for example, just, wise, good, merciful, powerful, and loving, although not in such a way that defines the essence of God and not in a manner that we can totally understand in this life (ST Ia. Given that human beings are rational and social creatures, that is, they were not created to live independently and autonomously with respect to other human beings, even in a perfect society a human society will have human laws. 1, a. q. Thomas thinks there are a number of human virtues, and so in order to offer an account of what he has to say about humanly virtuous activity (and its relationship to the imperfect human happiness we can have in this life), we need to mention the different kinds of human virtues. 65, a. 100, a. The first way was clearly indicative of his reasoning: There is something moving. However, how does Thomas distinguish morally good actions from bad or indifferent ones? Sometimes circumstances make an action that is bad according to its species even worse. 3. However, what goes for courage goes for temperance and justice, too. In the broadest sense, that is, in a sense that would apply to all final causes, the final cause of an object is an inclination or tendency to act in a certain way, where such a way of acting tends to bring about a certain range of effects. In other words, they are gifts of God that enable human beings to look to God himself as the object of a happiness that transcends the natural powers of human beings. 7; and ST IaIIae. Given human nature, Thomas thinks that such conversions were miraculous and so testify to the truth of the faith that such people came to adopt. (Thomas commented on Job, Isaiah, Jeremiah, Lamentations, Psalms 1-51 (this commentary was interrupted by his death), Matthew, John, Romans, 1 and 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, 1 and 2 Thessalonians, 1 and 2 Timothy, Titus, Philemon, and Hebrews. By popular demand, an all new three-minute philosophy lesson! Nonetheless, Thomas argues there would have been human authorities, that is, some human beings governing others, in the state of innocence. During life, an individual's will must be ordered toward right things (such as charity, peace and holiness), which requires morality in everyday human choices, a kind of Virtue Ethics. 100, a. According to Thomas, moral virtue “perfects the appetitive part of the soul by directing it to good as defined by reason” (ST IaIIae. 2], like a window in a house is that by which we see what is outside the house.) However, such knowledge requires a perfected knowledge about the rational ends or principles of human action, for one cannot perfectly know how to apply the principles of action in a given situation if one does not perfectly know the principles of action. Jean Oesterle (Notre Dame, IN: The University of Notre Dame Press, 1995). Thomas thinks I can know what a thing is, for example, a donkey, since the form of a donkey and my intelligible species of a donkey are identical in species (see, for example, SCG III, ch. In so falling, the frog is not acting as an efficient cause. q. English translation: Pasnau, Robert C., trans. Above the substantial forms of compounds, the substantial forms of living things, including plants, reach a level of perfection such that they get a new name: “soul” (see, for example: Disputed Question on the Soul [QDA] a. However, if Susan believes p by faith, Susan may see that p is true, but she does not see why p is true. Thomas begins with the accounts of healings, the resurrection of the dead, and miraculous changes in the heavenly bodies, as contained in the Old and New Testaments. For example, Thomas commented on all of Aristotle’s major works, including Metaphysics, Physics, De Anima, and Nichomachean Ethics. 4, n. 574). However, this need not be morally evil, even a venial sin, as long as it is not inconsistent with reason, just as sleep, which hinders reason, is not necessarily evil, for as Thomas notes, “Reason itself demands that the use of reason be interrupted at times” (ST IaIIae. We thus use the word “good” as an analogous expression in Thomas’ sense. q. Of course, most people—unless they are doing theology or philosophy—will not make such principles of practical action explicit. In a case of complete or uncontrolled equivocation, we predicate of two things (x and y) one and the same name n, where n has one meaning when predicated of x and n has a completely different meaning when predicated of y. English usage of the word “bank” is a good example of complete or uncontrolled equivocation; here the use of the same name is totally an accident of language. Thomas Aquinas applied this philosophical discourse to his Five Ways to Prove the Existence of God: 1) Motion; 2) Causation; 3) Contingency; 4) Goodness; 5) Design. For example, Thomas thinks that it is morally permissible for a community to put a criminal to death on the authority of the one who governs that community. 7). 4, a. The first part of the second part is often abbreviated “IaIIae”; the second part of the second part is often abbreviated “IIaIIae.”. He was the foremost classical proponent of natural theology at the peak of Scholasticism in Europe, and the founder of the Thomistic school of philosophy and theology. Thomas attributes to Plato of Athens the following view: (P) A human being, for example, Socrates, is identical to his soul, that is, an immaterial substance; the body of Socrates is no part of him. Recent scholarship has suggested that Thomas rather composed the work for Dominican students preparing for priestly ministry. Therefore, whatever pure perfections exist in creatures must pre-exist in God in a more eminent way (ST Ia. Finally, the substantial forms of human beings have operations (namely, understanding and willing) that do not require bodily organs at all in order to operate, although such operations are designed to work in tandem with bodily organs (see, for example, SCG II, ch. That being said, to live merely in accord with the natural law is not proportionate to the life that human beings live in heaven, which life, by the grace of God, human beings can, in a limited sense, begin to live even in this life. Thomas calls this ultimate material cause of a substance that can undergo substantial change prime matter. 79, a. However, such classifications are not substantial for Thomas, but merely accidental, for Socrates need not be (or have been) a philosopher—for example, Socrates was not a philosopher when he was two years old, nor someone who chose not to flee his Athenian prison, for even Socrates might have failed to live up to his principles on a given day. This is no accident. 34, a. In order for this to occur, Thomas speaks of the need of the sensible species being worked on by the power of phantasia. Thomas has much to say about the specific characteristics of virtuous human action, especially morally virtuous action. However, if those in authority in a community have set a timetable for an execution, say, that it should occur no sooner than Wednesday at 5 PM, and John the executioner, on his own authority, kills the prisoner on Wednesday at 10 AM (where John is not also an authority in the community), then the circumstances of John’s act of killing make what might otherwise have been a morally permissible act to be an immoral act. Still, we might wonder why Thomas thinks it is reasonable to accept the Catholic faith as opposed to some other faith tradition that, like the Catholic faith, asks us to believe things that exceed the capacity of natural reason. In addition to the appetitive power of the will, there are appetitive powers in the soul that produce acts that by nature require bodily organs and therefore involve bodily changes, namely, the acts of the soul that Thomas calls passions or affections. English translation: M. Pattison, J. D. Dalgairns, and T. D. Ryder, trans. Thomas agrees, but with a very important caveat. For our purposes, consider fideism to be the view that states that faith is the only way to apprehend truths about God. This distinction between an ultimate end and the ultimate end is important and does not go unnoticed by Thomas. Thomas is often spoken of as an Aristotelian. 4, a. One way to talk about this “just seeing” that some moral propositions are true is by making reference to what Thomas calls natural law. Such actions would also be excessive and deficient, respectively, and not morally virtuous. No account of Thomas’ philosophy of science would be complete without mentioning the doctrine of the four causes. Thomas calls such a union the beatific vision. The memorative power is that power that retains cognitions produced by the estimative power. Who Was Thomas Aquinas? q. According to Thomas, temperance is the virtue whereby the passions of touch participate in reason so that one is habitually able to say “no” to desires of the flesh that are not in accord with right reason (ST IaIIae. 1, a. 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.) However, properties or features that a being can gain or lose without going out of existence are accidental forms. For present purposes, this article focuses on the first four of these literary genera. Therefore, God also is not a composite of substance and accidental forms. Apparently, they were thinking that Thomas would, like any typical young man, satisfy the desires of his flesh and thereby “come back down to earth” and see to his familial duties. In that case there would be no reason why the being acted as it did. For example, John finds Jane attractive, and thereby John decides to go over to Jane and talk to her. Finally, there is prudence. An efficient cause of x is a being that acts to bring x into existence, preserve x in existence, perfect x in existence, or otherwise bring about some feature F in x. 7. Aquinas was born around 1225 to a noble family in the small town of Roccasecca, near Aquino, Italy, in what was then the Kingdom of Sicily. 64, a. 3, which is an argument from motion, with Thomas’ complete presentation of the argument from motion in SCG, book I, chapter 13. In general terms, Thomas thinks virtuous human actions are actions that perfect the human agent that performs them, that is, good human actions are actions that conduce to happiness for the agent that performs them. For Thomas, metaphysics involves not only disciplined discussion of the different senses of being but rational discourse about these principles, causes, and proper accidents of being. It is important to mention Thomas’ Scripture commentaries since Thomas often does his philosophizing in the midst of doing theology, and this is no less true in his commentaries on Scripture. q. (G3) The second-best form of non-mixed government is an aristocracy. The will is therefore an inclination in rational beings towards an object or act because of what the intellect of that being presents of that object or act as something desirable or good in some way. Furthermore, since the contrary of the best is the worst, and tyranny is the contrary of kingship, tyranny is the worst form of government (De regno, ch. However, because angels are not pure act—this description is reserved for the first uncaused efficient cause alone for Thomas—there is need to make sense of the fact that an angel is a composite of act and potency.
