This paper focuses on the theory of plurality of realities introduced by Leon Chwistek. A critical analysis of this theory and an extensional interpretation of Chwistek’s axiomatic descriptions of four realities lead to an epistemological interpretation of this theory. The word “plurality” in the title is a result of different waysof understanding the same original set of sense-data. This interpretation is contrasted with Kazimierz Pasenkiewicz’s ontological version of this theory. In the final parts of the paper the most important consequences (...) of this theory are discussed. First, the ethical relativism postulated by Chwistek is criticized. Second, an attempt to illustrate the plurality of realities with an example of different styles of painting is discussed. Third, a critical rationalism in the form of a kind of practical attitude toward social reality, which results from the theory of plurality of realities, is outlined. (shrink)

Aristotle contends that in perception the sense organ is “made like” its object, but only “in a certain way.” Much controversy has surrounded these remarks, primarily about how to understand being “made like.” One camp has understood this to require literal exemplification, such that the sense organs manifest the sensible qualities of their objects. Others have understood likeness to require no physical alteration at all in the sense organs.I accept as a starting point in this paper that understanding perceptual likeness (...) in terms of exemplification is a non-starter. By doing so, however, I also reject the easiest and most direct understanding of what it means for the sense organs to be “made like” their objects. Others who have shared this assumption have suggested that likeness consists in “isomorphism.” Unfortunately, they have not adequately explicated how this notion is to be understood, with the result that Aristotle’s theory of perception remains crucially underdeveloped. I argue that the key is to understand the form of isomorphism at work in Aristotle’s account of thinking. (shrink)

Principally under the influence of Saul Kripke (1972), philosophical semantics since the closing decades of 20th century has been dominated by thephenomenon Nathan Salmon (1986) aptly dubbed Direct Reference “mania.” Accordingly, it is now practically orthodox to hold that the meanings of proper names are entirely exhausted by their referents and devoid of any descriptive content. The return to a purely referential semantics of names has, nevertheless, coincided with a resurgence of some of the very puzzles that motivated description theories (...) of names in the first place, to wit: the informativeness of true identity statements of the form ‘a=b’ and the failure of substitutivity salve veritate for co-referential names in propositional attitude ascriptions. I argue that a Metalinguistic Description Theory of proper names, which treats the meaning of an arbitrary proper name as roughly equivalent to the definite description ‘the bearer of NN,’ offers a novel, semantically innocent solution to these puzzles when synthesized with Keith Donnellan’s (1966) insight that descriptions are semantically ambiguous between attributive and referential meanings. The ensuing account is then defended against two well-known Kripkean objections to metalinguisticsemantics: the Circularity Objection and the Paderewski Puzzle. (shrink)

The purpose of this paper is to re-examine the debate about cinematic motion in terms of the necessity for reception conditions in art. I shall argue that Gregory Currie’s rejection of weak illusionism – the view that cinematic motion is illusory – is sound, because cinematic images really move, albeit in a response-dependent rather than garden-variety manner. In §1 I present Andrew Kania’s rigorous and compelling critique of Currie’s realism. I assess Trevor Ponech’s response to Kania in §2, and show (...) that his focus on the cinematic experience is indicative of the direction the debate should take. §3 demonstrates that the issue is underpinned by the question of the role of reception conditions in the experience of art. In §4 I apply my observations on reception conditions to the problem of cinematic motion and conclude that Kania’s objections are unsuccessful due to his failure to acknowledge the necessary conditions for cinematic experience.

I first show in this paper how twentieth century Set Theory got into its greatest tangle by, amongst other things, regarding relational remarks like ‘Rxy’ asbinary functions. I then show how the lack of indexicality, and of ‘that’-clauses, in Modern Logic led that subject into its intractable difficulties with the Theory of Truth. Both errors arose not only through a contempt for ordinary language, but also through the related failure to recognise that being logical is not a matter of being (...) brainy, but of being coherent. It is not a mathematical talent, but a literary one. Later in the paper I go on to demonstrate this same conclusion with respect to Modal Logic and General Intensional Logic, and in particular with respect to fictions, since these are the central items that have been misunderstood, as is witnessed in some recent writings of Graham Priest.
