Carroll William Westfall has claimed that building types can serve as natural symbols of (the purposes served by) activities such as venerating, celebrating, trading, and dwelling. The aim of this paper is to interpret Westfall’s claim in a way that makes it non-trivial and yet worthy of further investigation. In particular, an attempt is made to explain the connection between building types and what they symbolize without appealing to convention. The question is also answered whether a non-conventional connection is compatible with one and the same building type having a different significance in different cultures.

In The Aesthetics of Architecture, Roger Scruton makes at least four claims about rightness of architectural proportion. The present paper lists those claims, briefly discusses the way they are related, and, finally, selects one as the topic of discussion: the claim that there cannot be an exact, mathematical definition of rightness of proportion. Scruton’s arguments for this claim are reviewed. The first is found to be substantially correct, whereas the second is found to rely on a mistaken assumption, namely the assumption that rightness of proportion is relative to a point of view. The paper ends by arguing that either the real or the apparent proportions of a building have to be definitely right, and that neither can be allowed to be definitely wrong.

We examine a formal semantics for counterfactual conditionals due to Judea Pearl, which formalizes the interventionist interpretation of counterfactuals central to the interventionist accounts of causation and explanation. We show that a characteristic principle validated by Pearl’s semantics, known as the principle of reversibility, states a kind of irreversibility: counterfactual dependence (in David Lewis’s sense) between two distinct events is irreversible. Moreover, we show that Pearl’s semantics rules out only mutual counterfactual dependence, not cyclic dependence in general. This, we argue, suggests that Pearl’s logic is either too weak or too strong

Echoing a distinction made by David Wiggins in his discussion of the relation of identity, this paper investigates whether aesthetic adjectives such as ‘beautiful’ are sortal-relative or merely sortal-dependent. The hypothesis guiding the paper is that aesthetic adjectives, though probably sortal-dependent in general, are sortal-relative only when used to characterize multifunctional artefacts. This means that multifunctional artefacts should be unique in allowing the following situation to occur: for some object x there are sortals K and K' such that x is a beautiful K and also a K', but not a beautiful K'. Examples of multifunctional artefacts show that this is indeed a possibility. However, that multifunctional artefacts are unique in this respect will be demonstrated by a more principled argument, taking into account the nature of functions on the one hand, and the nature of artefact-classification on the other hand.

According to Locke’s Principle, material objects are identical if and only if they are of the same kind and once occupy the same place at the same time. There is disagreement about whether this principle is true, but what is seldom disputed is that, even if true, the principle fails to constitute an applicable criterion of identity. In this paper, I take issue with two arguments that have been offered in support of this claim by arguing (i) that we can have knowledge of past whereabouts, and so verify the right hand side of Locke’s Principle, without having to assess concrete identity claims first; (ii) that even under conditions of incomplete knowledge of past whereabouts we can use Locke’s Principle to decide concrete identity problems.

The aim of this paper is to derive a perfectly general criterion of identity through time from Locke’s Principle, which says that two things of the same kind cannot occupy the same space at the same time. In this way, the paper pursues a suggestion made by Peter F. Strawson almost thirty years ago in an article called ‘Entity and Identity’. The reason why the potential of this suggestion has so far remained unrealized is twofold: firstly, the suggestion was never properly developed by Strawson, and secondly, it seemed vulnerable to an objection that he himself raised against it. Consequently, the paper’s aim is to further develop Strawson’s suggestion, and to show that the result is not vulnerable to the objection that seemed fatal to its underdeveloped predecessor. In addition, the paper aims to defend Locke’s Principle against alleged counterexamples such as those produced by Leibniz, Fine and Hughes.

Aesthetic properties are often thought to have either no evaluative component or an evaluative component that can be isolated from their descriptive component. The present article argues that this popular view is without adequate support. First, doubt is cast on the idea that some paradigmatic aesthetic properties are purely descriptive. Second, the idea that the evaluative component of an aesthetic property can always be neatly separated from its descriptive component is called into question. Meanwhile, a speculative hypothesis is launched regarding the structure of being garish and being cacophonous. Finally, an explanation is given of how the issue of the structure of aesthetic properties bears on their reality and (presumed) response-dependence.

A series of unnoticeably small changes in an observable property may add up to a noticeable change. Crispin Wright has used this fact to prove that perceptual indiscriminability is a non-transitive relation. Delia Graff has recently argued that there is a 'tension' between Wright's assumptions. But Graff has misunderstood one of these, that 'phenomenal continua' are possible; and the other, that our powers of discrimination are finite, is sound. If the first assumption is properly understood, it is not in tension with but is actually implied by the second, given a plausible physical assumption.

Criteria of identity should mirror the identity relation in being reflexive, symmetrical, and transitive. However, this logical requirement is only rarely met by the criteria that we are most inclined to propose as candidates. The present paper addresses the question how such obvious candidates are best approximated by means of relations that have all of the aforementioned features, i.e., which are equivalence relations. This question divides into two more basic questions. First, what is to be considered a ‘best’ approximation. And second, how can these best approximations be found? In answering these questions, we both rely on and constructively criticize ground-breaking work done by Timothy Williamson. Guiding ideas of our approach are that we allow approximations by means of overlapping equivalence-relations, and that closeness of approximation is measured in terms of the number of mistakes made by the approximation when compared to the obvious candidate criterion.

The aim of this chapter is to understand how sortals determine what aesthetic properties an object has. It is argued that Frank Sibley’s notion of an ideal of beauty does not help us to achieve that aim. Instead, it is argued, the special aesthetic relevance of sortals is better understood by reference to the (non-aesthetic) ideas of normality and functionality associated with sortals. In passing, the paper also argues that there must be a maximum degree of beauty if non-comparative judgments of beauty are possible, as they seem to be.

According to Roy Sorensen [Philosophical Studies 100 (2000) 175–191] an object cannot differ aesthetically from its mirror image. On his view, mirror-reversing an object – changing its left/right orientation – cannot bring about any aesthetic change. However, in arguing for this thesis Sorensen assumes that aesthetic properties supervene on intrinsic properties alone. This is a highly controversial assumption and nothing is offered in its support. Moreover, a plausible weakening of the assumption does not improve the argument. Finally, Sorensen’s second argument is shown to be formally flawed. As a result, the case for the aesthetic irrelevancy of orientation seems still open.

In this paper, we take another look at the reasons for which the causal criterion of event identity has been abandoned. We argue that the reasons are not strong. First of all, there is a criterion in the neighborhood of the causal criterion—the counterfactual criterion—that is not vulnerable to any of the putative counterexamples brought up in the literature. Secondly, neither the causal criterion nor the counterfactual criterion suffers from any form of vicious circularity. Nonetheless, we do not recommend adopting either the causal or the counterfactual criterion because, given a sufficiently lax principle of event composition, neither criterion can be applied to complex events. This we regard as a (prima facie) undesirable restriction on their applicability.
