This paper argues that Dummett’s interpretation of the relationship between Frege’s anti-psychologism and Wittgenstein’s doctrine that meaning is use results in a misreading of Frege. It points out that anti-mentalism is a form of anti-psychologism, but that mentalism is not the only version of psycholgism. Thus, while Frege and Wittgenstein are united in their opposition to mentalism, they are not equally opposed to psychologism, and from Frege’s point of view, the doctrine that meaning is use could also imply a version of psychologism. It then offers a realist and externalist reading of Frege’s understanding of concepts, which is more in line with what Frege intended by anti-psychologism.

Michael Dummett has argued that a formal semantics for our language is inadequate unless it can be shown to illuminate to our actual practice of speaking and understanding. This paper argues that Frege’s account of the semantics of predicate expressions according to which the reference of a predicate is a concept (a function from objects to truth values) has exactly the required characteristics. The first part of the paper develops a model for understanding the distinction between objects and concepts as an ontological distinction. It argues that, ontologically, we can take a Fregean function to be generated by a property detection device that can register for any object the presence or absence of that property. This provides a direct connection between the semantics of sentences and the structure of perceptual judgment. The second part of the paper deals with arguments that have been mounted against the coherence of Frege’s semantics. It argues that some of these are question begging, while others are correct in so far as Frege’s claim is untenable if we assume that the syntactic categories singular term and predicate are primary, and the ontological categories are simply projections of these syntactic categories. However, the objections dissipate once we recognize that an independent ontological characterization of the distinction is available.

In his late fragment, ‘Sources of Knowledge of Mathematics and Natural Sciences’ Frege laments the tendency to confuse functions with objects and says, ‘It is here that the tendency of language by its use of the definite article to stamp as an object what is a function and hence a non-object, proves itself to be the source of inaccurate and misleading expressions and also of errors of thought. Probably most of the impurities that contaminate the logical source of knowledge have their origins in this.’ This paper applies Frege’s logical insights to a series of influential modal arguments for the existence of souls or minds, in order to demonstrate that they hinge on the error of treating functions as objects. Related arguments have also resulted in the claim that identity statements are necessary, and that apparent identities ‘really’ involve relations of constitution. Here it is argued that once we recognise that all these arguments involve the assimilation of objects and concepts (which Frege identifies with functions) they can be seen to be defective.

Dummettian anti-realism–the refusal to endorse bivalence–is generally thought to be associated with idealism This paper argues that this is only true of the position developed by early Dummett. In a later manifestation Dummettian anti-realism is better thought of as providing the logic for anti-realisms of an error theoretic kind. Early on Dummett distinguished deep from shallow arguments for giving up bivalence: deep arguments followed a strong ‘sufficiency’ reading of Frege’s context principle, and made the sentence the primary vehicle of meaning. Enriched by an account of truth in terms of verifiability, deep arguments implied a form of linguistic idealism. From within a perspective that had already made ontology relative to theory, it was natural for the difference between realism and idealism to hinge on the notion of truth for sentences. Having given up the distinction between deep and shallow arguments against bivalence, Dummett, post 1990, asserts that every rejection of bivalence leads to a form of anti-realism. In the intervening years, he has also come to cast doubt on the sufficiency reading of the context principle, particularly as developed by Crispin Wright. These doubts open the space for some more simple-minded criticisms of this strong version of the context principle, developed in the paper. Once the sufficiency reading of the context principle is given up, arguments for failing to assert bivalence come to hinge on beliefs about ‘genuine’ existence. These forms of anti-realism cannot be taken to imply idealism. Rather, in many cases they will be the expression of views of an error-theoretic kind, that are quite compatible with a thorough-going rejection of idealism.

This ground-breaking book surveys the history of women's political thought in Europe from the late medieval period to the early modern era. The authors examine women's ideas about topics such as the basis of political authority, the best form of political organisation, justifications of obedience and resistance, and concepts of liberty, toleration, sociability, equality, and self-preservation. Women's ideas concerning relations between the sexes are discussed in tandem with their broader political outlooks; and the authors demonstrate that the development of a distinctively sexual politics is reflected in women's critiques of marriage, the double standard, and women's exclusion from government. Women writers are also shown to be indebted to the ancient idea of political virtue, and to be acutely aware of being part of a long tradition of female political commentary. This work will be of tremendous interest to political philosophers, historians of ideas, and feminist scholars alike.

Despite the fact that the High-Church Tory, Mary Astell, held political views diametrically opposed to the Whiggish Catharine Trotter Cockburn and Catharine Macaulay, it is here argued that their metaethical views were surprisingly similar. All were influenced by a blend of Christian universalism and Aristotelian eudaimonism, which accepted the existence of a law of nature, that we strive for happiness, and that happiness results from living in accord with our God-given nature. They differed with regard to epistemological issues; the means by which we can know the law of nature, and with regard to the characterization of that nature; our telos. Traces of the ethical theories developed by these women can also be seen in the works of the philosophically informed novelists, Sarah Fielding, Jane Collier, Sarah Scott, and Hannah More.

Argues that like more conservative feminist writers, Gabrielle Suchon and Mary Astell, writing earlier in the Eighteenth Century, Macaulay's concept of liberty is closely tied to virtue and involves free self government according to reason. Unlike these earlier writers from this concept of liberty she deduces the rationality of democratic republican government. Thus the grounds on which she builds her republicanism involve a very different concept of rational self interest to that usually assumed to ground social contract theory. For virtue and the genuine self interest of rational beings are taken to coincide.

I. Logic, rationality and ideology Herbert Marcuse once claimed that the ‘“rational” is a mode of thought and action which is geared to reduce ignorance, destruction, brutality, and oppression.’ He echoed a widespread folk belief that a world in which people were rational would be a better world. This could be taken as an optimistic empirical conjecture: if people were more rational then probably the world would be a better place (a trust that ‘virtue will be rewarded’, so to speak). However, it is also worth considering a stronger hypothesis: that if something did not reduce ignorance, destruction, brutality, and oppression then it would not constitute rationality. On this view there is no mere correlation between rationality and a propensity toward reduction in ignorance and the rest, it is the propensity to reduce ignorance, destruction, brutality and oppression which in part constitutes rationality. Call this a broad conception of rationality, because it expands beyond the epistemic goal of reducing ignorance, and reaches out to moral concerns like oppression.
