    Abailard and non-things
    Journal of the History of Philosophy 5 (4): 329-342. 1967.
    In lieu of an abstract, here is a brief excerpt of the content:Abailard and Non-Things MARTIN M. TWEEDALE On SEVERAL OCCASIONSin his logical writings Abailard extracts himself from embarrassing ontological implications of his analyses of language by resorting to the notion of a something that is not a thing. I shall note here two such occasions and then discuss Abailard's explanations of this procedure based on the grammatical distinction of personal and impersonal constructions. Since the texts…Read more

    Once Alexander of Aphrodisias revived the Peripatetic philosophy in the late secondcentury CE, Aristotle's surviving corpus became the guiding texts for a philosophicalschool, and, like any school, the Aristotelian one tried to systematize and dogmatizeits founder's teachings into a coherent and comprehensive approach to everything. Thisway of reading Aristotle was the dominant one through the Islamic and Christian Middle Ages, although occasionally a dissenter might express some doubt about how…Read more

    In this important collection, the editors argue that medieval philosophy is best studied as an interactive discussion between thinkers working on very much the same problems despite being often widely separated in time or place. Each section opens with at least one selection from a classical philosopher, and there are many points at which the readings chosen refer to other works that the reader will also find in this collection. There is a considerable amount of material from central figures suc…Read more

    Aristotle's Motionless Soul
    Dialogue 29 (1): 123-. 1990.
    Whether or not we adopt some form of physicalism in our thinking about the psychology of humans and other organisms we all believe that a mind is something that comes into being, changes, develops and decays. The correlation of the development and then later the decay of our mental powers with changes in the brain post-dates our belief that the mental realm is as much an area where things ebb and flow, come to be and pass away, as is the physical. Even ancient authors who hold to the indestructi…Read more

    Two of the best currently practising scholars of Ockham, Marilyn Adams and Paul Spade, seem to have accepted a reading of Ockham's ontological program which, although it contains much that is uncontroversially correct, attributes to Ockham a reductionist view that is on my interpretation of his works far too radical to be genuinely Ockham's. Their reading runs as follows. So far as entities go, Ockham accepts only particular substances and some particular qualities. Aristotle's categories, accor…Read more

    Aristotle’s Realism
    Canadian Journal of Philosophy 18 (3). 1988.
    Although there are a very few occasions on which Aristotle speaks of words, on the one hand, or mental concepts, on the other, as universals, he was no nominalist and no conceptualist. This negative thesis I have argued sufficiently, at least to my own satisfaction, in an earlier paper. He was, rather, a realist, but of a very tenuous sort. As I said in the earlier paper, he viewed universals as real entities but lacking numerical oneness; each is numerically many, and yet each is also one in so…Read more

    Basic Issues Medieval Philosophy (edited book)
    with Richard N. Bosley
    Broadview Press. 1997.
    Two ideas govern the organisation of this collection. It is suggested that medieval philosophy is best studied as an interactive debate between thinkers of different times, and also the importance of the Ancient Greek philosophers in this field.
