Of those that exist, some are said of a subject, but are in no subject: as man is said of some subject, namely of some man, but is in no subject. Others, however, are in a subject, but are said of no subject. And I say that to be in a subject which, while it is in something not as a part, cannot exist apart from the thing in which it is. For example, some particular literacy is in a subject, namely in the soul, but is not said of any subject, and this whiteness is in a body as in its subject, for any color is in a body. Others both are said of and are in a subject. For example, knowledge is in the soul, and is said of a subject, say, of literacy. Still others neither are in a subject, nor are said of a subject, for example, some particular man, or some particular horse: for none of these is either in or is said of a subject. In general, individuals, and what are numerically one are said of no subject, but nothing prevents them from being in a subject, for some particular literacy is in a subject.

This paper argues that Aquinas's conception of the human soul and intellect offers a consistent alternative to the dilemma of materialism and post-Cartesian dualism. It also argues that in their own theoretical context, Aquinas' arguments for the materiality of the human soul and immateriality of the intellect provide a strong justification of his position. However, that theoretical context is rather "alien" to ours in contemporary philosophy. The conclusion of the paper will point in the direction of what can be done to render Aquinas's position more palatable to contemporary philosophers.

This volume is the first annotated translation in any language of the entire text of the Summulae de dialectica, by the Parisian master of arts John Buridan (1300-1358). One of the most influential works in the history of late medieval philosophy, the Summulae is Buridan's systematic exposition of his nominalist philosophy of logic. Buridan's doctrine spread rapidly and for some two hundred years was dominant at many European universities. His work is of increasing interest today not only to historians of medieval philosophy but also to modern philosophers, several of whom find in Buridan's ideas important clues to problems of contemporary philosophy. Gyula Klima provides a substantial introduction to Buridan's life and work and discusses his place in the history of logic. Through extensive notes Klima assists philosopher and medievalist alike to read Buridan with understanding and insight. Those with a philosophical interest in the relations among the structures of language, thought, and reality will find much to ponder in the Summulae.
