Any account of intentional action has to deal with the problem of how such actions are individuated. Medieval accounts, however, crucially differ from contemporary ones in at least three respects: for medieval authors, individuation is not a matter of description, as it is according to contemporary, ‘Anscombian’ views; rather, it is a metaphysical matter. Medieval authors discuss intentional action on the basis of faculty psychology, whereas contemporary accounts are not committed to this kind of psychology. Connected to the use of (...) faculty psychology is the distinction between interior and exterior acts. Roughly, interior acts are mental as opposed to physical acts, whereas exterior acts are acts of physical powers, such as of moving one’s body. Of course, contemporary accounts are not committed to this distinction between two ontologically different kinds of acts. Rather, they might be committed to views consistent with physicalist approaches to the mind. The main interpretative task in this paper is to clarify how Scotus and Ockham explain moral intentional action in terms of the role and involvement of these kinds of acts respectively. I argue that Scotus’s account is close to contemporary, ‘Anscombian’ accounts, whereas Ockham’s account is incompatible with them. (shrink)

The aim of this paper is to show that, unlike proponents of Humean accounts of intentional action, Ockham can also answer the fundamental question of why we desire anything at all. For Ockham, desire cannot be the starting point of the explanation, since desire presupposes yet another kind of appetitive act that is objectual, or non-propositional, in its nature. Ockham calls this love (amor). It should become clear that Ockham's approach, even in his day, is not common. It is, however, (...) worthy of detailed examination because it furthers a deeper and more complete understanding of intentional action by shedding light on this more fundamental question. In his terminology, love is the most basic kind of unconditional willing, not least because it is purely objectual: we appreciate persons as ends, not as means. The explanation of intentional action has to start somewhere. And, for Ockham, it starts with love for persons. (shrink)

Artykuł stanowi próbę zarysowania kilku istotnych wątków dwóch istotnych średniowiecznych koncepcji celowości. Twórcami owych koncepcji są Jan Duns Szkot i Walter Chatton. Autor skupia się na trzech zagadnieniach: (1) argumentach na rzecz przyjęcia teleologii naturalnej, (2) statusie ontologicznym celu, (3) statusie Boga jako przyczyny celowej. Dokonywane analizy mają pokazać, iż wiele poglądów wygłaszanych przez Dunsa Szkota i Chattona stanowiło podważenie wcześniejszej scholastycznej wizji całościowej teleologii, która swą najbardziej dojrzała postać otrzymała w myśli Tomasza z Akwinu, przygotowując nadejście nowożytnej krytyki celowości.

In this paper, I argue that it is in the fourteenth century that the problem of the compatibility or unity of efficient and final causality emerges. William Ockham and John Buridan start to flirt with a mechanized view of nature solely explainable by efficient causality, and they hence push final causality into the human mind and use it to explain for example action, morality and the good. Their argumentation introduces the problem of how to give a unified account of the (...) world, that is, how are nature and freedom compatible. In the paper, I set up the discussion by going through some of the problems associated with final causality in the seventeenth century and show that Ockham and Buridan's problems are similar. I then argue using a formulation from Leibniz's Monadology that the problems here traced should be seen as versions of the mind/body problem. (shrink)

Causality plays an important role in medieval philosophical writing: even before the rediscovery of Aristotle's major works, the created universe was seen as a rational manifestation of God's action. In the later Middle Ages, the dominant genre of medieval academic writing was the commentary on an authoritative work: Aristotle's Physics and Metaphysics were frequently commented on, and both contain a great deal of material on causation. So the nature of the philosophical and theological themes which were popular in the Middle (...) Ages led to an emphasis on causality. Writers studied the interrelationship of divine grace and natural processes, the role of the will in ethics, free will and determinism: all of these problems have an important causal component.
