The Treatise on Univocation is an early work on the fallacy called univocation. This fallacy is a kind of ambiguity due to the shifted reference of words in a sentence when the ambiguity does not fall under the well-known Aristotelian kinds (equivocation, composition and division, . . .). Examples include the shift of reference of common terms due to tense and modality; e.g. the shift whereby the reference of 'giraffe' is extended to past or future giraffes when the tense of the sentence 'A giraffe is spotted' is made past or future, and the shift whereby the reference of 'giraffe' is extended to merely possible giraffes in the sentence 'A giraffe can be spotted'. The translation is by Elizabeth Karger.

It is tempting to think that Meinong overlooked the "specific/nonspecific" distinction. For example, 'I am looking for a grey horse' may either mean that there is a specific horse I am looking for, or just that I am grey-horse-seeking. The former reading, and not the latter, requires for its truth that there be a grey horse. The purpose of this paper is to investigate whether it is defensible to maintain Meinong's theory here: to take nonspecific reading of any verb concerning a possibly non-existent but incomplete object. This requires essential appeal to the distinction between nuclear and extranuclear properties. Included is a discussion of criticisms of Meinong's own theory, and of the Medieval theory of ampliation, according to which psychological discourse can "ampliate" a term such as 'chimera' so as to stand for one or more things that cannot exist, yet are chimeras. The paper concludes inconclusively.

This extended investigation of the semantics of event (and state) sentences in their various forms is a major contribution to the semantics of natural language, simultaneously encompassing important issues in linguistics, philosophy, and logic. It develops the view that the logical forms of simple English sentences typically contain quantification over events or states and shows how this view can account for a wide variety of semantic phenomena. Focusing on the structure of meaning in English sentences at a &"subatomic&" level&-that is, a level below the one most theories accept as basic or &"atomic&"&-Parsons asserts that the semantics of simple English sentences require logical forms somewhat more complex than is normally assumed in natural language semantics. His articulation of underlying event theory explains a wide variety of apparently diverse semantic characteristics of natural language, and his development of the theory shows the importance of seeing the distinction between events and states. Parsons demonstrates that verbs, also, indicate kinds of actions rather than specific, individual actions. Verb phrases, too, he argues, depend on modifiers to make their function and meaning in a sentence specific. An appendix gives many of the details needed to formalize the theory discussed in the body of the text and provides a series of templates that permit the generation of atomic formulas of English.

This paper arose from an attempt to determine how the very late medieval1 supposition theorists treated anaphoric pronouns, pronouns whose significance is derivative from their antecedents. Modern researches into pronouns were stimulated in part by the problem of "donkey sentences" discussed by Geach 1962 in a section explaining what is wrong with medieval supposition theory. So there is some interest in seeing exactly what the medieval account comes to, especially if it turns out, as I suspect, to work as well as contemporary ones. Besides, finding a good analysis of pronouns has proved to be very difficult, and so we might possibly find some insight in a historically different kind of approach. I discuss a version of supposition theory that aims at producing analyses of sentences containing quantified terms,2 as articulated around 1400 by Paul of Venice, and as further developed by certain logicians such as de Soto and Celaya in the 1400's and early 1500's.3 Much of what I will say also applies indirectly to earlier versions of supposition theory (before 1400)

This paper has two goals. The first is to formulate an adequate account of the semantics of the progressive aspect in English: the semantics of Agatha is making a cake, as opposed to Agatha makes a cake. This account presupposes a version of the so-called Aristotelian classification of verbs in English into EVENT, PROCESS and STATE verbs. The second goal of this paper is to refine this classification so as to account for the infamous category switch problem, the problem of how it is that modification of a verb like run by an adverbial like to the store can turn a PROCESS phrase (run) into an EVENT phrase (run to the store). Views discussed include those of Aqvist, Bach, Bennett, Bennett and Partee, Dowry, Montague and Scott, and Vendler.

This paper follows up a suggestion by Paul Vincent Spade that there were two Medieval theories of the modes of personal supposition. I suggest that early work by Sherwood and others was a study of quantifiers: their semantics and the effects of context on inferences that can be made from quantified terms. Later, in the hands of Burley and others, it changed into a study of something else, a study of what I call global quantificational effect. For example, although the quantifier in ‘¬∀xPx’ is universal, it can be seen globally as having an existential effect; this is because the formula containing it is equivalent to ‘∃x¬Px’. The notion of global effect can be explained in terms of the modern theory of normal forms. I suggest that early authors were studying quantifiers, and the terminology of the theory of personal supposition is a classification of kinds of quantifiers. In this theory, to say that a term has distributive supposition is to say, roughly, that it is quantified by a universal quantifying sign. Later authors turned this into a theory of global quantificational effect. In the later theory, to say that a term has distributive supposition is to say that the overall effect is as if the term were universally quantified with a quantifier taking (relatively) wide scope. The difference between these two approaches is illustrated by the fact that the term ‘man’ is classified as having distributive ("universal") supposition in ‘Not every man is running’ in the earlier theory, whereas in the later theory that term does not have distributive supposition; it has determinate ("existential") supposition. In the paper I explain these options, and I argue from several texts that the earlier and later medieval theories actually worked like this. In an appendix I make further efforts to clarify the obscure early accounts, as well as the nineteenth century "doctrine of distribution". The last section of the paper discusses the "purpose(s)" of supposition theory

Peter Geach describes the 'doctrine of distribution' as the view that a term is distributed if it refers to everything that it denotes, and undistributed if it refers to only some of the things that it denotes. He argues that the notion, so explained, is incoherent. He claims that the doctrine of distribution originates from a degenerate use of the notion of ?distributive supposition? in medieval supposition theory sometime in the 16th century. This paper proposes instead that the doctrine of distribution occurs at least as early as the 12th century, and that it originates from a study of Aristotle's notion of a term's being ?taken universally?, and not from the much later theory of distributive supposition. A detailed version of the doctrine found in the Port Royal Logic is articulated, and compared with a slightly different modern version. Finally, Geach's arguments for the incoherence of the doctrine are discussed and rejected
