Margaret Macdonald was at the institutional heart of analytic philosophy in Britain in the mid-twentieth century. However, her views on the nature of philosophical theories diverge quite considerably from those of many of her contemporaries. In this article, I focus on Macdonald’s provocative 1953 paper, “Linguistic Philosophy and Perception,” in which she argues that the value of philosophical theories is more akin to that of poetry or art than science or mathematics. I do so for two reasons. First, it reveals (...) just how far Macdonald’s metaphilosophical views diverged from those of many of her contemporaries. Second, the discussion in her article preempts recent literature on the nature of philosophical inquiry and the efficacy of philosophical arguments. Indeed, Macdonald’s paper is just as likely to provoke discussion today as it was in the 1950s. (shrink)

In this paper, I show that, in a number of publications in the early 1950s, Margaret Macdonald argues that art does not admit of definition, that art is—in the sense associated with Wittgenstein—a family resemblance concept, and that definitions of art are best understood as confused or poorly expressed contributions to art criticism. This package of views is most typically associated with a famous paper by Morris Weitz from 1956. I demonstrate that Macdonald advanced that package prior to Weitz, indeed, (...) prior to any other philosopher of art of the period. Despite this, Macdonald’s contribution is nowhere to be found in the subsequent literature on the definition of art. In closing, I raise the prospect that Macdonald was in fact the primary influence on the development of Weitz’s critique of the definitional project. (shrink)

In this article, I offer a detailed examination of Margaret Macdonald's response to the Cartesian sceptical argument from dreaming. I show that Macdonald's views were not well understood by her contemporaries, and I suggest that this misunderstanding has led to her omission from subsequent discussions of this subject. I end with a brief demonstration of the fact that Macdonald's central claims have re-emerged in contemporary epistemology.

I argue that Helen Knight and Margaret Macdonald expressed views on the nature of ‘good’ in aesthetic contexts which anticipate to a striking extent the dispute between Peter Geach and R. M. Hare over ethical uses of ‘good’ several years later. I show that Knight introduced a distinction between uses of adjectives later drawn also by Geach, and that she employed that distinction, as Geach did, in order to defend a descriptivist approach to ‘good’ according to which ‘good’ is not (...) ambiguous. I also show that Macdonald conceived of evaluative statements as commendatory, and that her conception of evaluative language therefore closely resembles the position which Hare would later advance.

This essay (a revised version of my undergraduate honors thesis at Stanford) constructs a theory of analogy as it applies to argumentation and reasoning, especially as used in fields such as philosophy and law. The word analogy has been used in different senses, which the essay defines. The theory developed herein applies to analogia rationis, or analogical reasoning. Building on the framework of situation theory, a type of logical relation called determination is defined. This determination relation solves a puzzle about (...) analogy in the context of logical argument, namely, whether an analogous situation contributes anything logically over and above what could be inferred from the application of prior knowledge to a present situation. Scholars of reasoning have often claimed that analogical arguments are never logically valid, and that they therefore lack cogency. However, when the right type of determination structure exists, it is possible to prove that projecting a conclusion inferred by analogy onto the situation about which one is reasoning is both valid and non-redundant. Various other properties and consequences of the determination relation are also proven. Some analogical arguments are based on principles such as similarity, which are not logically valid. The theory therefore provides us with a way to distinguish between legitimate and illegitimate arguments. It also provides an alternative to procedures based on the assessment of similarity for constructing analogies in artificial intelligence systems. (shrink)

The discipline of philosophy has been critiqued from both within and outside itself. One brand of external critique is associated with Conceptual Metaphor Theory (CMT), the view that human cognition is partially structured by pervasive and automatic mappings between conceptual domains. Most notably, Lakoff and Johnson (1999) claimed that many central philosophical concepts and arguments rely on an unacknowledged metaphorical substructure, and that this structure has sometimes led philosophy astray. The purpose of this paper is to argue that Lakoff and (...) Johnson's critique is anticipated by the work of post‐Tractarian Wittgenstein and his student, Margaret MacDonald. In the Blue Book, Wittgenstein outlines a method for identifying and resolving philosophical puzzles generated by misused grammatical analogies, although his discussion lacks a precise characterization of exactly how and why such analogies lead to trouble. In a 1938 paper, MacDonald offers such a characterization, which I outline and then connect back to Wittgenstein. In addition to this interpretive work, I supplement Wittgenstein and MacDonald's diagnosis using evidence from CMT which suggests that linguistic metaphors and analogies often originate in or are motivated by more fundamental analogical mappings in cognition. The supplemented account carries implications for how philosophical arguments ought to be formulated and critiqued. (shrink)
