"Self-Knowledge and the Science of the Soul in Buridan's Quaestiones De Anima"

Buridan holds that the proper subject of psychology (i.e., the science undertaken in Aristotle’s De Anima) is the soul, its powers, and characteristic functions. But, on his view, the science of psychology should not be understood as including the body nor even the soul-body composite as its proper subject. Rather its subject is just “the soul in itself and its powers and functions insofar as they stand on the side of the soul". Buridan takes it as obvious that, even thus narrowly construed, such a science is possible. To the extent that this science includes the human or intellective soul, however, Buridan’s claim regarding its possibility is far from obvious. After all, like most of his contemporaries, Buridan takes the human soul to be immaterial. Thus, he readily admits that “the intellect cannot be sensed” and its operations are likewise inaccessible to the senses. Yet, on Buridan's broadly empiricist theory of knowledge, all (human) knowledge, including knowledge of the intellect or intellective soul, takes its start in the senses. How, then, is a science of the human soul possible? What is the nature or source of our knowledge of the intellect? In this paper, I reconstruct Buridan's answer to these questions. My discussion divides roughly into two parts. In the first, I set out the main elements of Buridan’s account of how we come to cognize the intellect, focusing on what he says about the genesis of our concept of the intellect. I then consider his account of our cognition of our own intellective states. As the discussion in part one make clear, Buridan holds that our concepts of intellect and of intellective states are both derived (inferentially) from subjective “experience” of our own states and rational activities. In part two, therefore, I try to elucidate Buridan’s notion of experience. Ultimately, I argue that it is a non-conceptual, non-discursive mode of self-awareness. I suggest, moreover, that it might best be understood in terms of our own notion of phenomenal consciousness. On the interpretation I advance, then, it turns out that, for Buridan, our concept of the intellect itself and, hence, the science of (human) psychology in general, is ultimately grounded in phenomenal experience of our own intellective states

Olivi on Consciousness and Self-Knowledge: the Phenomenology, Metaphysics, and Epistemology of Mind's Reflexivity

The theory of mind that medieval philosophers inherit from Augustine is predicated on the thesis that the human mind is essentially self-reflexive. This paper examines Peter John Olivi's (1248-1298) distinctive development of this traditional Augustinian thesis. The aim of the paper is three-fold. The first is to establish that Olivi's theory of reflexive awareness amounts to a theory of phenomenal consciousness. The second is to show that, despite appearances, Olivi rejects a higher-order analysis of consciousness in favor of a same-order theory. The third and final is to show that, on his view, consciousness is both self-intimating and infallible

How Chatton Changed Ockham’s Mind

It is well-known that Chatton is among the earliest and most vehement critics of Ockham’s theory of judgment, but scholars have overlooked the role Chatton’s criticisms play in shaping Ockham’s final account. In this paper, I demonstrate that Ockham’s most mature treatment of judgment not only contains revisions that resolve the problems Chatton identifies in his earlier theories, but also that these revisions ultimately bring his final account of the objects of judgment surprisingly close to Chatton’s own. Even so, I argue that, at the end of the day, there remain significant differences between their respective analyses of the structure and intentionality of judicative states

Intuition, Externalism, and Direct Reference in Ockham

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

Ockham on Judgment, Concepts, and the Problem of Intentionality

In this paper I examine William Ockham’s theory of judgment and, in particular, his account of the nature and ontological status of its objects. Commentators, both past and present, habitually interpret Ockham as defending a kind of anti-realism about objects of judgment. My aim in this paper is two-fold. The first is to show that the traditional interpretation rests on a failure to appreciate the ways in which Ockham’s theory of judgment changes over the course of his career. The second, and larger, aim is to show that careful attention to these changes in Ockham’s account (and to the motivations for them) sheds new light on broader developments in his philosophy of mind—specifically, on his views about the nature of concepts and on his account of the nature and structure of intentionality itself

Perception in Augustine's De Trinitate 11: A Non-Trinitarian Analysis

In this paper, I explore Augustine’s account of sense cognition in book 11 of De Trinitate. His discussion in this context focuses on two types of sensory state—what he calls “outer vision” and “inner vision,” respectively. His analysis of both types of state is designed to show that cognitive acts involving external and internal sense faculties are susceptible of a kind of trinitarian analysis. A common way to read De Trin. 11, is to interpret Augustine’s account of “outer” vision as an analysis of sense perception and his account “inner” vision as an analysis of occurrent sensory memory and imagination. I argue against such a reading of De Trin. 11, however. Insofar as we take perception to be a phenomenally conscious mode of sensory awareness, outer vision cannot, I claim, be the equivalent of ordinary sense perception. For, on Augustine’s view, the deliverances of outer vision only reach the threshold of consciousness, when outer vision occurs in conjunction with inner vision. Hence, on my analysis, sense perception turns out to be a complex, hybrid state—one that involves both outer and inner vision. If I am right, acts of sense perception turn out not to be directly susceptible to trinitarian analysis. Even so, the account is interesting and nuanced for all that
