Jabir ibn Hayyan, for a long time the reigning alchemical authority both in Islam and the Latin West, has exercised numerous generations of scholars. To be sure, it is not only the vexed question of the historical authorship and dating of the grand corpus Jabirianum which poses a serious scholarly challenge; equally challenging is the task of unraveling all those obscure and tantalizing discourses which it contains. This book, which marks the first full-scale study of Jabir ever to be published in the English language, takes up both challenges. The author begins by critically reexamining the historical foundations of the prevalent view that the Jabirian corpus is the work not of an 8th-century individual, but that of several generations of Shi'i authors belonging to the following century and later. Tentatively concluding that this view is problematic, the author, therefore, infers that its methodological implications are also problematic. Thus, developing its own methodological matrix, the book takes up the second challenge, namely that of a substantive analysis and explication of a Jabirian discourse, the Book of Stones. Here explicating Jabir's notions of substance and qualities, analyzing his ontological theory of language and unraveling the metaphysics of his Science of Balance, the author reconstructs the doctrinal context of the Stones and expounds its central theme. He then presents an authoritative critical edition of a substantial selection of the text of the Stones, based on all available manuscripts. This critical edition has been translated in its entirety and is provided with exhaustive commentaries and textual notes -- another pioneering feature of this book: for this is the first English translation of a Jabirian text to emerge in print after a whole century. An outstanding contribution is that it announces and presents an exciting textual discovery: the author has found in the Stones a hitherto unknown Arabic translation of part of Aristotle's Categories. Given that we have so far known of only one other, and possibly later, classical Arabic translation of the Greek text, Haq's discovery gives this book an historical importance.

This study offers a ckomprehensive new interpretation of one of Plato's dialogues, the Cratylus. Throughout, the book combines analysis of Plato's arguments with attentiveness to his philosophical method.

Rhyming text depicts a father sharing with his child such things as seven words that all mean blue and the name of every kind of cloud.

The book is concerned with the child's acquisition of names (by which is meant words that refer to objects - including proper names, common nouns in some uses, and pronouns in some uses). Four chapters in the book's first section, Matters Mainly Psychological, describe empirical observations that explore how a child copes with the fact that many different name-like words can be applied to a single object. A second major section, Matters Mainly Linguistic, contains chapters on phonology, the learning of grammatical categories, the definite and indefinite articles, and the plural. A third section, Matters Mainly Philosophical, focuses entirely on the complex issues of reference and meaning. A final chapter reflects on the implications of the book for developmental psychology.An MIT Press/Bradford Book.

Originally published in 1973. In this systematic treatise, Anthony Quinton examines the concept of substance, a philosophical refinement of the everyday notion of a thing. Four distinct, but not unconnected, problems about substance are identified: what accounts for the individuality of a thing; what confers identity on a thing; what is the relation between a thing and its appearances; and what kind of thing is fundamental, in the sense that its existence is logically independent of that of any other kind of thing? In Part 1, the first two problems are discussed, while in Part 2, the third and fourth are considered. Part 3 examines four kinds of thing that have been commonly held to be in some way non-material: abstract entities; the un-observable entities of scientific theory; minds and their states; and, finally, values. The author argues that theoretical entities and mental states are, in fact, material. He gives a linguistic account of universals and necessary truths and advances a naturalistic theory of value.

Why is it so hard to make lasting changes in our companies, in our communities, and in our own lives? The primary obstacle is a conflict that's built into our brains, say Chip and Dan Heath, authors of the critically acclaimed bestseller Made to Stick. Psychologists have discovered that our minds are ruled by two different systems - the rational mind and the emotional mind—that compete for control. The rational mind wants a great beach body; the emotional mind wants that Oreo cookie. The rational mind wants to change something at work; the emotional mind loves the comfort of the existing routine. This tension can doom a change effort - but if it is overcome, change can come quickly. In Switch, the Heaths show how everyday people - employees and managers, parents and nurses - have united both minds and, as a result, achieved dramatic results: • The lowly medical interns who managed to defeat an entrenched, decades-old medical practice that was endangering patients • The home-organizing guru who developed a simple technique for overcoming the dread of housekeeping • The manager who transformed a lackadaisical customer-support team into service zealots by removing a standard tool of customer service In a compelling, story-driven narrative, the Heaths bring together decades of counterintuitive research in psychology, sociology, and other fields to shed new light on how we can effect transformative change. Switch shows that successful changes follow a pattern, a pattern you can use to make the changes that matter to you, whether your interest is in changing the world or changing your waistline.
