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

8Criss-crossing a Philosophical LandscapeGrazer Philosophische Studien 42 229-259. 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.

7Stanisław Leśniewski: Original and Uncompromising Logical GeniusIn Urszula Wybraniec-Skardowska & Ángel Garrido (eds.), The Lvov-Warsaw School. Past and Present, Springer- Birkhauser,. pp. 209-221. 2018.Stanisław Leśniewski was one of the two originators and drivers of the Warsaw School of logic. This article describes his work chronologically, from his early philosophical work in Lvov to his highly original logical systems of protothetic, ontology and mereology. His struggles to overcome logical antinomies, his absolute commitment to logical clarity and precision, and his antipathy towards set theory made his nominalistic approach to logic among the most original of the twentieth century, whil…Read more

Past and Present, Springer- Birkhauser,. pp. 337-359. 2018.This paper surveys mereology, the theory of parts and wholes, focussing on its origins in Leśniewski, and noting its intended employment as a surrogate for set theory. We examine parallel and independent work by Whitehead, Leonard and Goodman, and outline the subsequent adventures of mereology, both in its formal guises and in its now intensive application within philosophical ontology.

3WaysKriterion - Journal of Philosophy 1 (7): 12-15. 1994.ABSTRACT There is more than one way to kill a cat. What are ways? Very little has been written about them in general, but they appear at crucial places in many philosophical discussions. Clarity over the ontology of ways could help in several areas of philosophy. After indicating where ways have been mentioned, I discuss briefly the corresponding linguistic feature, adverbs of manner, before outlining three theories: a Platonistic one making ways a complex kind of function, a Davidsonian one in …Read more
