About this topic
Summary Thomas Aquinas (c. 1225-1274) is the most influential Christian philosopher and theologian of the Scholastic period. His influence is primarily due to his synthesis of Aristotelian philosophy with Christian theology, as well as the breadth and systematic rigor of his writings. He wrote extensively on philosophical theology, metaphysics, epistemology, human nature (including philosophy of mind) and ethics (including moral psychology, virtue ethics, and natural law theory). The wide-ranging appeal of his theories have inspired a variety of "Thomisms" throughout the 20th century, under such prefatory labels as "Existential," "Transcendental," "Phenomenological," and "Analytical." His philosophical system has been explicitly promoted as the foundation par excellence for Catholic theology by Pope Leo XIII and Pope John Paul II.  
Key works For a comprehensive collection of Aquinas's works (in Latin) see Opera Omnia. Aquinas's most significant writings are the voluminous Summa theologiae and Summa contra Gentiles. Among his philosophical writings are comprehensive commentaries on Aristotle's works, including Metaphysics, Physics, De anima, Nicomachean Ethics, Politics, and Posterior Analytics. Extensive arguments on certain topics can be found in collections of Disputed Questions on subjects such as truth, virtue, evil, the soul, and the power of God. Shorter, yet philosophically impactful, treatises Aquinas wrote include On Being and Essence and On Kingship.
Introductions A classical introduction to Aquinas's overall philosophical thought is Gilson 1956. An excellent recent introductory text is Davies 1993. A more in-depth scholarly treatment of various themes in Aquinas's philosophical system is provided by Eleonore 2003.

  1. The Power of God: By Thomas Aquinas.Saint Thomas (Aquinas) (ed.) - 2012 - Oxford University Press USA.
    On Power (De Potentia) is one of Aquinas's ''Disputed Questions'' (a systematic series of discussions of specific theological topics). It is a text which anyone with a serious interest in Aquinas's thinking will need to read. There is, however, no English translation of the De Potentia currently in print. Fr. Richard Regan has produced this abridgement, which passes over some of the full text while retaining what seems most important when it comes to following the flow of Aquinas's thought.

    This article explains Aquinas's attempt to show, within an Aristotelian framework, how the soul can be both a substance in its own right and the form of the body. I argue that although Aquinas' theory is logically consistent, its plausibility is weakened by the fact that it requires a significant modification of the Aristotelian conceptions of both substance and form.

    In this study, I have compared Avicenna's position concerning the nature of creative action and the beginning of the universe to that of Aquinas. As a preliminary, I discussed whether their theories can be examined on the same criteria; and affirmed that they can be because they have similar positions concerning the source of our knowledge of God and its expression. Subsequently, I have discussed whether they have a similar conception of God, to which the differences between their positions regarding (...)

    This article examines two medieval sermons that examine philosophic and halakhic issues: the Passover sermon of Hasdai Crescas, which discusses the laws of Passover, and a sermon of Zerahia Halevi Saladin, a disciple of Crescas, which probes an aspect of the laws of vows ( nedarim ). In the analysis of Zerahia's sermon, a comparison is made between his discussion and Thomas Aquinas's examination of vows in his Summa Theologica . The comparison establishes the dependency of Zerahia on Aquinas regarding (...)

Ribeirão (Portugal): Ediçoes Húmus. pp. 61-80.
    El estudio acerca de la influencia de las pasiones en el voluntario libre ha sido recurrente en la tradición tomista. Sin embargo, las causas de los dos efectos psicológicos de la intentio volitiva mencionados por Tomás de Aquino, la redundantia y la distractio, pasaron desapercibidas, y podrían aclarar algunos comportamientos consecuencia de la dinámica de las pasiones del hombre. La acción de la intentio volitiva originada por los afectos, al alcanzar cierto grado de intensidad, puede llegar a sobrepasar el control (...)

    Desde la consideración de Tomás de Aquino del conocimiento por connaturalidad, "el conocimiento que aporta a la inteligencia más datos que los puramente racionales, especialmente todos los datos proporcionados por la afectividad", es posible hacer un acercamiento integral a la realidad y establecer una relación con otras áreas de sabiduría y sus objetos de estudio. Esto ayuda a confrontar algunos problemas filosóficos reales, como la pérdida de la visión holística de la realidad, el reduccionismo epistemológico y el relativismo gnoseológico. Recordar (...)
  17. DIMENSIONES DEL CONOCIMIENTO AFECTIVO.Miguel Acosta - 2000 - Pamplona, Spain: Servicio de Publicaciones de la Universidad de Navarra, Cuadernos de Anuario Filosófico 102.
    En la cúspide del conocimiento humano halla su sede la sabiduría. Un saber que se alcanza en la simplicidad más alta del ser humano, allí donde confluyen todas sus potencias y facultades, no solamente la inteligencia, sino también la voluntad y los afectos. Cualquier clase de conocimiento aséptico respecto de cualquier influencia afectiva o volitiva lleva a una reducción que de manera propia puede llamarse “intelectualismo”. El concepto de razón “pura” es un reduccionismo que conduce a una grave disgregación en (...)

  19. Aquinas and Modern Contractualism.Don Adams - 2009 - International Journal of Philosophical Studies 17 (4):509 – 530.
    When modern ethical contractualists defend their view against “teleology,” they typically have in mind utilitarian or consequentialist theories according to which valuable states of affairs are to be promoted. But if we look to older teleological theories e.g. that found in the philosophy of St. Thomas Aquinas we will find a kind of teleology that can be incorporated beneficially into contractualist ethics. In this paper I argue that Scanlon would be well served, on grounds to which he appeals, to make (...)
  20. Aquinas and Modern Consequentialism.Don Adams - 2004 - International Journal of Philosophical Studies 12 (4):395 – 417.
    Because the moral philosophy of St Thomas Aquinas is egoistic while modern consequentialism is impartialistic, it might at first appear that the former cannot, while the latter can, provide a common value on the basis of which inter-personal conflicts may be settled morally. On the contrary, in this paper I intend to argue not only that Aquinas' theory does provide just such a common value, but that it is more true to say of modern consequentialism than of Thomism that it (...)

    One of the more attractive features of Greek moral philosophy and its medieval dependents is that it provides an obvious motivation for being moral: rational self-interest. Socrates, Plato, Aristotle and Aquinas are all rational egoists, and each argues that acting only for the sake of one's own happiness is compatible with treating other people morally. Each bridges the gap between egoism and altruism by arguing that a rational person has sufficient reason to care about other people. This raises two main (...)

    The paper tackles the question of the relevance of emotions in ethics. It argues that emotions are discerning and thus inherent components of morality and they deserve a place in adequate ethical projects. The paper engages into a conversation with Martha C. Nussbaum and Thomas Aquinas. Specifically, it presents accounts of compassion and anger to illustrate the discerning nature of these emotions and the moral value they might signal.

    Students of Thomas Aquinas have so far lacked a comprehensive study of his doctrine of the transcendentals. This volume fills this lacuna, showing the fundamental character of the notions of being, one, true and good for his thought. The book inquires into the beginnings of the doctrine in the thirteenth century and explains the relation of the transcendental way of thought to Aquinas's conception of metaphysics. It analyzes 'Being', 'One', 'True', 'Good' and 'Beautiful' individually and discusses their importance for the (...)

  37. Aquinas and the Human Desire for Knowledge.Jan A. Aertsen - 2005 - American Catholic Philosophical Quarterly 79 (3):411-430.
    This essay examines Aquinas’s analysis of the human desire to know, which plays a central role in his thought. (I.) This analysis confronts him with the Aristotelian tradition: thus, the desire for knowledge is a “natural” desire. (II.) It also confronts him with the Augustinian tradition, which deplores a non-virtuous desire in human beings that is called “curiosity.” (III.) Aquinas connects the natural desire with the Neoplatonic circle motif: principle and end are identical. The final end of the desire to (...)

The thesis of this paper is that the question of truth is essential for the understanding of his doctrine of the transcendentals.The first part of the paper (sections 1–4) analyzes Thomas''s conception of truth. Two approaches to truth can be found in his work. The first approach, based on Aristotle''s claim that truth is not in things but in the (...)
