The nature and content of the thought of Duns Scotus (c. 1266-1308) remains largely unknown except by the expert. This book provides an accessible account of Scotus' theology, focusing both on what is distinctive in his thought, and on issues where his insights might prove to be of perennial value.

When William of Ockham lectured on Lombard's "Sentences" in 1317-1319, he articulated a new theory of knowledge.

CHAPTER I LOGICISM AND PHILOSOPHY In the preface to his Phenomenology of Mind, Hegel rightly remarks that knowing a philosophical system is something more ...

In the not too distant past, it was common to treat Hume's skeptical doubts regarding the justification of our beliefs in causal connections—understood as necessary connections between objects or events—as having appeared per conceptionem immaculatam in his post-Cartesian mind. Thanks to recent efforts by scholars in early modern philosophy, however, we are now more informed about the roots of Hume's conclusions in Cartesian thought itself, especially the influence of Malebranche and his arguments for occasionalism. And by the research of historians (...) of Medieval philosophy we are reminded that many aspects of seventeenth-century occasionalism, in turn, have their ancestry in Latin and Arabic thought of the Middle Ages. In this paper I offer a small contribution to the overall project of illuminating the precedents in Medieval philosophy for the theses and arguments in Malebranche that so clearly influenced the most important and influential philosophical analysis of causation ever. There is a tradition here, where the goal is to undermine claims to discover real causal relations or powers in nature. I will concentrate on one particular aspect or tool of that tradition: the negative argument that we can never perceive a sufficiently necessary connection between any two natural objects or events.

In this paper I challenge recent externalist interpretations of Ockham’s theory of intuitive cognition. I begin by distinguishing two distinct theses that defenders of the externalist interpretation typically attribute to Ockham: a ‘direct reference thesis’, according to which intuitive cognitions are states that lack all internal, descriptive content; and a ‘causal thesis’, according to which intuitive states are wholly determined by causal connections they bear to singular objects. I then argue that neither can be plausibly credited to Ockham. In particular, (...) I claim that the causal thesis doesn’t square with Ockham’s account of supernaturally produced intuition and that the direct reference thesis sits uneasily with Ockham’s characterization of the intentional structure of intuitive states.

Originally published in 1993, Modalities in Medieval Philosophy looks at the idea of modality as multiplicity of reference with respect to alternative domains. The book examines how this emerged in early medieval discussions and addresses how it was originally influenced by the theological conception of God acting by choice. After a discussion of ancient modal paradigms, the author traces the interplay of old and new modal views in medieval logic and semantics, philosophy and theology. A detailed account is given of (...) late medieval discussions of the new modal logic, epistemic logic, and the logic norms. These theories show striking similarities to some basic tenets of contemporary approaches to modal matters. This work will be of considerable interest to historians of philosophy and ideas and philosophers of logic and metaphysics. (shrink)

Against the background of changing assessments of Nominalism and its meanings before Ockham, this book examines the reception of Ockham's thought at Oxford and ...

Wilfrid Sellars charged that mediaeval philosophers confused the genuine intentionality of thinking with what he called the “pseudo-intentionality” of sensing. I argue that Sellars’s charge rests on importing a form of mind/body dualism that was foreign to the Middle Ages, but that he does touch on a genuine difficulty for mediaeval theories, namely whether they have the conceptual resources to distinguish between intentionality as a feature of consciousness and mere discriminative responses to the environment. In the end, it seems, intentionality (...) cannot be “the mark of the mental” as contemporary philosophy usually takes it. (shrink)

This is a radically new interpretation of the nature of the power of God, as understood by such thinkers as Aquinas in the Middle Ages. The book provides a clear and illuminating discussion of their arguments, focusing on the distinction they made between so-called 'absolute' and 'ordained' divine power. It is full of important insights into the work of some of the key thinkers of the period, and also challenges modern theologians with the relevance and importance of these ideas today.

Three philosophical questions that are often confused should instead be keep distinct: First, what is a thought? Second, what is that in virtue of which a thought is a thought? Third, what is it that determines of what a thought is a thought? These questions raise very different issues within Ockham’s philosophy. Although Ockham’s views about the first question evolve, he seems to answer the second and the third questions in the same way, maintaining throughout his career that the intentionality (...) of thoughts, which he expresses in terms of signification, is a primitive feature of them. Ockham’s view contrasts sharply with the view that can be found in Aquinas and others that a thought is a form of being present in an immaterial way. This alternative view explains intentionality by reducing it to the co-presence of a number of non-cognitive factors. This latter view offers hope of unifying epistemology and such sciences as optics but at the price of a very peculiar ontology. Ockham avoids this peculiarity, but his way of doing so raises issues about what determines the taxonomy of thoughts, and about whether the items which are thoughts are essentially so or whether by God’s power they could exist without being thoughts. Despite Ockham’s terminology of similitude, the taxonomy of thoughts is not fixed by internal features of the metaphysical items which are thoughts but by the objects of the thoughts, and this suggests a negative answer to the questions whether thoughts are essentially thoughts, an answer that Ockham seems not to draw explicitly but which is explicit in the work of some, like Pierre d’Ailly, who are much influenced by him.

Scotus’ natural theology has distinctive claims: (i) that we can reason demonstratively to the necessary existence and nature of God from what is actually so; but not from imagined situations, or from conceivability-to-us; rather, only from the possibility logically required for what we know actually to be so; (ii) that there is a univocal transcendental notion of being; (iii) that there are disjunctive transcendental notions that apply exclusively to everything, like ‘contingent/necessary,’ and such that the inferior cannot have a case (...) unless the superior does; (iv) that an a priori demonstration of the existence of God is impossible because there is nothing explanatorily prior to the divine being, and so, reasoning must be a posteriori, from the real dependences among things we perceive to the possibility of an absolutely First Being (The First Principle); (v) that such a being cannot be possible without existing necessarily; and (vi) that the First Being (God) is simple, omni-intelligent, free (spontaneous), omnipotent and, positively infinite;[1] and moreover, (vii) that there is a formal distinction, that is more than a distinction within our concepts or definitions, among the divine attributes. He makes that first point obvious throughout his several treatments, that one cannot reliably reason from conceptual consistency for us to the real and formal possibility or necessity of something; one must reason only to those necessities that are conditions of the possibility of what is known to be actual. The schema of the reasoning is, in a word, that “only the existence of God can make an effect even possible”[2]. Thus, it is explicitly incorrect to classify him along with St Anselm, Descartes and Leibniz, among those who reason a priori to the being of God[3]. He characteristically and deftly argues by indirect proof. He supposes the opposite of his intended conclusion and deduces a contradiction between that supposition and certain self-evident, or previously proved propositions, thus, getting his own conclusion by using the principle that whatever entails the denial of what is already known to be so, is false and its opposite is true,[4] “si negatur negatio, ponitur affirmatio.”[5] He also uses the argument form, “ if ‘p’ is not necessary, then ‘not-p’ is possible”..

In this volume, the world's foremost Scotus scholars collaborate to present the latest research on his work.

Sukjae Lee John Duns Scotus believes it to be undeniably true that we human beings have free will. He does not argue for our freedom but rather explains it. There are two elements which are both characteristic of and essential to Scotus’ account of human will: namely, 1) the will as a self-determining power for opposites, thus a ‘rational’ power; and 2) the ‘dual affections of the will.’2 The significance of each element taken separately is comprehensible if not obvious. We (...) are puzzled, however, when we attempt to ascertain the relation between the two. This paper is an attempt to reach an adequate understanding of this relation. (shrink)

Which are the philosophical consequences for one’s theory of objects and relations if one posits that every intentional act is correlated with an intentional object? In what follows, I tackle that question in examining the case of Franciscus de Mayronis . After suggesting a typology of theories of intentionality distinguishing monadic, relational, and correlational theories, I go on to expose Franciscus’ ontology and his conception of relations. It turns out that Franciscus’ theory of intentionality exemplifies a pattern according to which (...) certain epistemic-psychological constraints have serious consequences on the ontology. (shrink)

This collective volume gives an exemplary overview over the philosophical reactions William of Ockham has provoked and also serves to better understand not only Ockham s thought in its historical context, but also the philosophy of the 14th century in general.".
