17Meinong's Theory of Sense and ReferenceGrazer Philosophische Studien 50 (1): 171-186. 1995.Gilbert Ryle wrote that "Meaning-theory expanded just when and just in so far as it was released from that 'Fido'-Fido box, the lid of which was never even lifted by Meinong". This paper sets out to relieve Ryle's oversimplification about Meinong and the role of meaning theory in his thought. One step away from canine simplicity about meaning is the recognition of a distinction between sense and reference, such as we find in Frege, Husserl, and the early Russell. In Über Möglichkeit und Wahrsche…Read more

16Parts Study in Ontology: A Study in OntologyOxford University Press UK. 1987.The relationship of part to whole is one of the most fundamental there is, yet until now there has been no full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail. This has far-reaching consequences for our understanding of s…Read more

14European and American PhilosophersIn Robert L. Arrington (ed.), A Companion to the Philosophers, Blackwell. 2017.Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categ…Read more

13Existential PropositionsGrazer Philosophische Studien 42 (1): 229-259. 1992.By considering a wide and expressly classified range of examples from natural and logical languages, the attempt is made to isolate from other concomitants the features of existential sentences which make them existential. One such concomitant is the imputation of singularity. There are many ways to say something exists, and their relationships are charted. It is denied that there is anything in reality called existence, or any special existential facts.

12Philosophy and Logic in central Europe from Bolzano to TarskiKluwer Academic Publishers. 1992.This book with an introduction by Witold Marciszewski, views the history of philosophy and logic from 1837 to 1939 from the perspective of the cradle of modern exact philosophy - Central Europe. In a series of case studies, it illuminates the developments in this region, most notably in Austria and Poland, examining thinkers such as Bolzano, Brentano, Meinong, Husserl, Twardowski, Lesniewski, and Tarski, as well as the logicians like Frege and Russell with whom they bore a close resemblance. The…Read more

11Who's Afraid of Higher-Order Logic?Grazer Philosophische Studien 44 (1): 253-264. 1993.Suppose you hold the following opinions in the philosophy of logic. First-order predicate logic is expressively inadequate to regiment concepts of mathematic and natural language; logicism is plausible and attractive; set theory as an adjunct to logic is unnatural and ontologically extravagant; humanly usable languages are finite in lexicon and syntax; it is worth striving for a Tarskian semantics for mathematics; there are no Platonic abstract objects. Then you are probably already in cognitive…Read more

11Tractatus Mereologico-Philosophicus?Grazer Philosophische Studien 28 (1): 165-186. 1986.The philosophies of late Brentano and early Wittgenstein can be brought closer in two ways. One way discovers a surprising amount of part-whole theory in the Tractatus if we see states of affairs (not wholly wilfully) as thinglike rather than factlike. This throws up a modal analogue to Chisholm's entia successiva in the form of situations. The other way sees all propositions as truth-functions of existential propositions, supporting Brentano's view that existentials are primary, and incidentall…Read more

11Samuel Alexander’s CategoriesIn A. R. J. Fisher (ed.), Marking the Centenary of Samuel Alexander’s Space, Time and Deity, Palgrave Macmillan. pp. 149-164. 2021.This chapter is concerned with the second of the four books of Samuel Alexander’s Space, Time, and Deity, which bears the title “The Categories.” It occupies 164 pages, a fifth of the total. While most systematic metaphysicians treat of categories in some form, it is rare for one to discuss the topic at such length: what we have is practically a treatise within a treatise. Alexander understands categories to be those qualities of space-time that are pervasive and fundamental. A comparative expos…Read more

10Formal ontology combines two ideas, one originating with Husserl, the other with Frege: that of ontology of the formal aspects of all objects, irrespective of their particular nature, and ontology pursued by employing the tools of modern formal disciplines, notably logic and semantics. These two traditions have converged in recent years and this is the first collection to encompass them as a whole in a single volume. It assembles essays from authors around the world already widely known for thei…Read more

9Mind and OpacityDialectica 49 (2-4): 131-146. 1995.Where there is mind there is representational opacity, and vice versa. Opacity arises because where there is representation there may be misrepresentation, and the status of the misrepresenting sign or state of the misrepresenting sign‐user can only be characterized via the terms used for a correctly represented object. Opacity is not a blight for naturalism, but must be recognized and exploited if naturalism is to adequately embrace the mental. Opacity is illustrated for language, for the menta…Read more
