Thomas Aquinas is commonly thought to hold that human beings will happiness and do so necessarily. This is taken to mean first that human beings are not able to will misery for the sake of misery and therefore not capable of pursuing misery for its own sake. Secondly, everything that human beings do will they will for the sake of happiness, and since human beings are moved to act on the basis of what they will, all of their actions are (...) performed for the sake of happiness. This claim is subject to doubt because it seems to many to be false on empirical grounds. Often, people choose things that they know and are willing to admit do not make them happy. Often, people choose things without even thinking about their happiness. Aquinas’s theory must deal adequately with such apparent counterexamples. But his account faces an objection of a different nature, an objection raised by John Duns Scotus. (shrink)

Thomism is a philosophical movement based on the writings of Thomas Aquinas. This chapter begins by explaining the historical context within which Thomism originated and some of the general issues arising in Thomistic discussions, and then considers the two main approaches to Thomistic ethics: eudaimonism and natural law. It concludes with an application of Thomistic ideas to a current discussion of justice and practical rationality, specifically Alasdair MacIntyre's treatment of Aquinas in his book, Whose Justice? Which Rationality?

There has been a great deal of interest in medieval action theory in recent years. Nonetheless, relatively little work has been done on figures prior to the so-called High Middle Ages, and much of what has been done has focused on better-known thinkers, such as Augustine and Anselm. By comparison, Bernard of Clairvaux's treatise, De gratia et libero arbitrio has been neglected. Yet his treatise is quoted widely by such important scholars as Philip the Chancellor, Alexander of Hales, and Albertus (...) Magnus. Some historians of philosophy argue that his writings inspired the voluntarist movement that developed in the 1270s. Thus, Bernard must be seen as an important influence upon later medieval theories of action. In this paper, I examine the basic structure of his interesting account of human action and its freedom and conclude by raising some further issues connected to his work. /// Nos últimos anos assistiu-se a uma retoma do interesse pela teoria medieval da acção. Apesar disso, poucos estudos têm versado sobre os pensadores anteriores à assim chamada Alta Idade Média, para além de que esses estudos se debruçam sobretudo sobre os filósofos mais conhecidos, como é o caso de Agostinho e de Anselmo. Comparativamente, o tratado de S. Bernardo de Claraval, De gratia et libero arbítrio, não tem suscitado muita atenção crítica. Contudo, numerosos pensadores citaram este tratado, entre eles Filipe o Chanceler, Alexandre de Hales, e Alberto Magno. Vários histonadores da filosofia têm avançado a tese de que os escritos de Bernardo influenciaram o movimento voluntarista que se desenvolveu nos anos 1270. Nesse sentido, as ideias de Bernardo de Claraval tiveram um certo impacto sobre as teorias da acção que haveriam de aparecer mais tarde. No presente artigo, a autora examina as ideias do pensador medieval sobre a acção humana e a sua liberdade, terminando com o levantar de algumas novas questões sobre o tratado de Bernardo de Claraval.

Medieval thinkers were both puzzled and fascinated by the capacity of human beings to do what is morally wrong. In this book, Colleen McCluskey offers the first comprehensive examination of Thomas Aquinas' explanation for moral wrongdoing. Her discussion takes in Aquinas' theory of human nature and action, and his explanation of wrong action in terms of defects in human capacities including the intellect, the will, and the passions of the sensory appetite. She also looks at the notion of privation, which (...) underlies Aquinas' account of wrongdoing, as well as his theory of the vices, which intersects with his basic account. The result is a thorough exploration of Aquinas' psychology which is both accessible and illuminating, and will be of interest to a wide range of readers in Aquinas studies, medieval philosophy, the history of theology, and the history of ideas.
