Psychological externalism is the thesis that the contents of many of a person's propositional mental states are determined in part by relations he bears to his natural and social environment. This thesis has recently been thrust into prominence in the philosophy of mind by a series of thought experiments due to Hilary Putnam and Tyler Burge. Externalism is a metaphysical thesis, but in this work I investigate its implications for the epistemology of the mental. I am primarily concerned with the (...) question whether externalism undermines the idea that a person typically knows the contents of her own thoughts, beliefs, and other propositional attitudes directly and authoritatively. I criticize arguments that have been advanced on behalf of a positive answer to this question, and argue that they rest on a faulty conception of the nature of first person authority, one which likens our access to our own minds to perception. An account of the basis of first person authority is sketched that locates our epistemic right to our self-ascriptions of propositional attitude not in our ability to discriminate among the various thought contents we might be thinking, but rather in our ability to express our thoughts, and to think with them in accordance with the norms of rationality. I consider also the question whether first person authority and externalism jointly make possible a refutation of certain forms of global skepticism, as has been famously argued by Putnam. I argue that Putnam's attempted refutation fails, because the crucial externalist claims that drive it are not knowable a priori. (shrink)

The problem of being is central to Western metaphysics. Etched sharply in the verses of Parmenides, it took on distinctive colouring in Aristotle as the subject matter of a science expressly labelled 'theological.' For Aristotle, being could not be shared in generic fashion by other natures. As a nature it had to be found not in various species but in a primary instance only. The science specified by the primary nature was accordingly the one science that under the aspect of (...) being treated universally of whatever is: it dealt with being qua being. (shrink)

Joseph Owens presents an introduction to metaphysics designed to develop in the reader a habitus of thinking. Using original Thomistic texts and Etienne Gilson's interpretation of St. Thomas Aquinas, Owens examines the application of metaphysical principles to the issues that arise in a specifically Christian environment. An Elementary Christian Metaphysics focuses on questions of existence and the nature of revealed truths. Following his historical introduction to metaphysics, Owens provides a general investigation of the first principles and causes of being and (...) also a study of knowledge and of the divine nature and attributes in light of natural reason. "Irrespective of one's intellectual genotype, an exposure to the sustained, developmental elucidation of Aquinas' insights executed by an author such as Owens can only enhance any metaphysical approach to reality." --The New Scholastic "An Elementary Christian Metaphysics is intended primarily for undergraduate students as an introduction to metaphysics. . . . The scope of the metaphysical study pursued by Owens includes not only a general investigation of beings but also an analysis of knowledge (epistemology) and of the divine nature, all in light of natural reason." --Studies in Religion Joseph Owens (1908-2005) taught philosophy at the Pontifical Institute of Mediaeval Studies and the University of Toronto for forty years. He is the author of a number of books, including An Interpretation of Existence, also published by the University of Notre Dame Press. (shrink)

I. An approach to the question of teleology in nature for Aristotle requires first of all a sufficiently clear understanding of the terms involved. In regard to the notion of teleology itself, there can hardly be any pertinent difficulty. The term is a modern one, and is quite definitely fixed in meaning by contemporary use. It seems to have been coined in eighteenth-century philosophical Latin to denote the study of final causes in nature. It became readily accepted in modern philosophical (...) vocabulary. Against this historical background it is commonly understood today to focus on “purposive or goal-directed activity.” In application to nature it assumes that purposive activity is present and asks how the activity is to be identified and described. The initial problem, accordingly, will lie not with the notion of teleology but rather with the other term, ‘nature’. (shrink)

Kripke's Pierre puzzle undermines some of the central epistemic intuitions that underlie traditional defences of the Fregean assumption that sentences'S believes that Fa ‘and'S believes that Fb’ can differ in truth value, even though a = b. Millian theorists have seized on this and employed the puzzle to reject the Fregean assumption itself. I argue that Millians are correct in rejecting traditional defences of the Fregean assumption, but they are wrong in rejecting the Fregean assumption itself. To this end, I (...) offer a different argument kr the assumption, one that is not open to Kripkean/millian objections. (shrink)

My primary goal in this paper is to focus attention on a certain conception of internal access, on the Cartesian conception that a rational subject's capacity to determine sameness and difference in explicit propositional attitudes is independent of knowledge of the external world. This conception of introspection plays a crucial, if unacknowledged, role in numerous arguments and theoretical positions. In particular, it plays a large role in motivating psychological internalism. I argue in favor of rejecting this epistemology and the internalism (...) it supports. (shrink)

There is a growing acceptance of the idea that the explanatory states of folk psychology do not supervene on the physical. Even Fodor (1987) seems to grant as much. He argues, however, that this cannot be true of theoretical psychology. Since theoretical psychology offers causal explanations, its explanatory states must be taxonomized in such a way as to supervene on the physical. I use this concession to invert his argument and cast doubt on the received model of folk psychological explanation (...) as causal explanation by intentionally individuated states. This in turn undermines the central model of cognitive theory--causal explanation by representational states. (shrink)

The relation between imagery and philosophy in the poem of Parmenides has occasioned much discussion in recent years. One item of particular import has been the direction taken by the journey that was so inspiringly pictured in the opening section. Is the travel upwards? Or is it downwards? Or is it rather cross-country, either aloft, or on the earth’s surface, or in the depths of the nether world? Further, if there is cross travel on any of these three levels, is (...) the direction from east to west, or from west to east? (shrink)

Cognition is a basic introductory text for college courses in the philosophy of knowledge. Joseph Owens, C.Ss.R., here expands the narrowly metaphysical treatment of knowledge given in his earlier book, An Elementary Christian Metaphysics, into a full-fledged epistemology. This text utilizes the traditions of Aristotle and Thomas Aquinas to reacquaint students of philosophy with a number of insights basic for a philosophic understanding of knowledge. These insights into the nature of abstraction, truth, the ground of certitude, and other major concerns (...) of epistemology will help students clarify the approaches of contemporary philosophies.

At a conference on ‘Leisure in Canada,’ held more than a decade ago at Montmorency in Quebec, a participant observed that ‘practically all writers on the subject take Aristotle as the point of departure in discussing leisure but seldom seem to move from that point.’ At first sight this statement may seem surprising. How is it to be understood? Certainly recent writers on leisure do in fact list Aristotle's conception as one of the significant positions on it.

FIVE 'WAYS' TO PROVE THAT GOD EXISTS ARE OFFERED IN AQUINAS' "SUMMA OF THEOLOGY," ALL TAKEN FROM HISTORICALLY TRACEABLE SOURCES IN WHICH THEY DID NOT REACH THE CONCLUSION ENVISAGED BY HIM. 'WAYS' UP TO ELEVEN IN NUMBER ARE IN FACT USED IN HIS WORKS. ALL FUNCTION IN A STRICTLY METAPHYSICAL--NOT COSMOLOGICAL OR TELEOLOGICAL--FRAMEWORK THAT WAS DEVELOPED EARLY IN HIS CAREER. THE ANSELMIAN AND OTHER ARGUMENTS THAT CANNOT FIT INTO THAT FRAMEWORK ARE REJECTED OR LEFT UNNOTICED, WHILE THOSE THAT DO FIT (...) IN ARE ACCEPTED IN LINE WITH THE CONVENIENCE OF THE MOMENT. ACCORDINGLY THE NUMBER AND ORDER OF THE 'FIVE WAYS' MEAN NO MORE THAN A MOMENTARY CONVENIENCE OF THIS TYPE. (shrink)

Explanation of cognition as a special way of being appears in Aristotle without traceable ancestry. Earlier, in Parmenides and in Empedocles, the notion that cognition is somehow equated with the physical constitution of the knower at any given moment had been put forward. But the now rather enigmatic fragments of those thinkers fail to show how this notion foreshadowed any new kind of being over and above the physical. In fact, would it not seem incongruous to use the term “being” (...) for something proposed by them in terms of change? ·. (shrink)

DIFFICULTIES about existence have plagued Western thought since the time of Parmenides. The Eleatic sage had concentrated on what was most obvious and most incontrovertible to him, namely, that something exists. He made that tenet the way and the test of truth. From it he drew consequences that succeeding Greek thinkers from Empedocles to Plotinus accepted in part and rejected in part, intrigued by much of what he had stated but repelled by seeming enormities in some of his conclusions. Later, (...) the patristic acceptation of being as the most appropriate name for God gave additional complication to the issue. In modern times the Kantian and linguistic approaches have raised the questions how existence is a predicate and whether there is a concept of it, and if so, what kind of a concept. On the other hand, the impact of Heidegger has inspired renewed and often enthusiastic absorption in the important role played by existence in philosophical thought, and current contacts with Hindu philosophies are furthering this interest.

These substances have been considered in recent times, as in traditional interpretation, to be identical with the immobile Movers of the Physics. Both Physics and Metaphysics refer to the same separate substances. On the other hand, the immobile Movers of the Physics have been identified with the immanent souls of the Heavens, and so sharply distinguished from the separate substances of the Metaphysics. Then in the opposite extreme, the Movers of the Metaphysics have been completely identified with the celestial souls. (...) Or again, the first only of the Movers has been declared separate, and the others identified with the different sphere-souls, among which is the first Mover of the Physics. In still another interpretation the first Mover alone is separate, but the other immobile Movers are held to be the divine thoughts, identical with the first Mover. Even the first Mover has been interpreted as a thought in the mind of some other Being, as merely an ideal or standard of goodness which does not imply--though it need not exclude--any corresponding existent reality in the Aristotelian universe.
