This volume is the first ever English translation of Kant's last major work, the so-called Opus Postumum, a work Kant himself described as his 'chef d'oeuvre' and as the keystone of his entire philosophical system. It occupied him for more than the last decade of his life. Begun with the intention of providing a 'transition from the metaphysical foundations of natural science to physics,' Kant's reflections take him far beyond the problem he initially set out to solve. In fact, he reassesses a whole series of fundamental topics of transcendental philosophy: the thing in itself, the nature of space and time, the concept of the self and its agency, the idea of God, and the unity of theoretical and practical reason. Though never completed, the text reaches a logical albeit not fully developed, conclusion.

The question of rules is not an issue that separates the 'analytical' and 'Continental' traditions from one another; rather it is an issue that is a source of division within each tradition. Within Continental philosophy the problem of the rule-governed character of cognition goes back to Kant's dualism of sense and understanding. Many philosophers in the Continental tradition (notably, Nietzsche, Gadamer and Adorno) have retained a quasi-Kantian conception of judgement while rejecting the idea of it as rule-governed. But there have been exceptions to this within Continental philosophy, most prominently, Jürgen Habermas. The rules thesis was implicit in much of analytical philosophy as it was practised in Britain from the 1950s to the 1970s. The doctrine gave support to a conception of philosophy (so-called 'ordinary-language philosophy') as essentially an exercise in the articulation of certain kinds of tacit knowledge. It was advocated explicitly in such works as Searle's Speech Acts and Winch's The Idea of a Social Science . The equation of meaning and rules enjoyed further prestige, for it was taken by many philosophers to be the central doctrine to be extracted from Wittgenstein's Philosophical Investigations . A most striking feature of the receding of the rules thesis has been the transformation of previously accepted interpretations of Wittgenstein's later philosophy (for example, by Stanley Cavell and John McDowell). Both adherents and opponents of the rules thesis have shared a common concern. In emphasizing the discontinuity between language and the subject-matter of the natural sciences both sides offer reassuringly positive answers to one of the besetting problems of twentieth-century philosophy: does philosophy have a distinctive subject-matter of its own?

Hegel's philosophy has often been compared to a circle of circles: an ascending spiral to its admirers, but a vortex to its critics. The metaphor reflects Hegel's claim to offer a conception of philosophical reason so comprehensive as to include all others as partial forms of itself. It is a claim which faces the writer on Hegel with peculiar difficulties. Criticism, it would appear, can always be outflanked; criticism of the system can be turned back into criticism within the system. Michael Rosen discusses the philosophical issues involved in historical interpretation before presenting a novel and challenging solution to the problem of Hegel's openness to criticism. Contrary to received opinion, Hegel's philosophy does not, he argues, draw upon a universal and pre-suppositionless conception of rationality. Rather, Hegel's originality lies in founding his system upon a particular, avowedly mystical conception of philosophical experience. This experience - Hegel calls it 'pure Thought' - is fundamental. Pure Thought makes speculative reasoning intelligible and, hence, underpins the claim to rationality of the entire system. Dr Rosen's conclusion is that all attempts at rehabilitation of Hegel are based on misunderstanding. When restored to their speculative-mystical shell the irrational kernel of Hegel's concepts becomes apparent.

Human history is a history of the domination of some groups by others, sustained in part by the willing subordination of the members of dominated groups. How can this remarkable fact be explained? On Michael Rosen’s telling, some of the best political theorists of the early modern period, from Machiavelli through Rousseau and Hume, grappled with this question. But it was, of course, in Marx’s work that the problem of voluntary servitude received its most philosophically trenchant and historically influential treatment. Rosen’s central claim is that Marx ultimately failed to explain this phenomenon satisfactorily. He does think that at least one self-described Marxist, Walter Benjamin, advanced promising suggestions, and he concludes On Voluntary Servitude with his own sketch of a solution, drawing in part on Jon Elster’s reconstructions of Marxist positions. But, as Rosen makes painfully clear, we are still some way from a full understanding of why people voluntarily accept forms of political domination opposed to their own interests.
