In quantum mechanics it is usually assumed that mutually exclusives states of affairs must be represented by orthogonal vectors. Recent attempts to solve the measurement problem, most notably the GRW theory, require the relaxation of this assumption. It is shown that a consequence of relaxing this assumption is that arithmatic does not apply to ordinary macroscopic objects. It is argued that such a radical move is unwarranted given the current state of understanding of the foundations of quantum mechanics.

The fact that especially few women survive in a subject that attracts roughly equal numbers of male and female undergraduates suggests that, while bothsexes are equally drawn to philosophy, there is something about the discipline that is discouraging to women.

Human genetics has blossomed from an obscure biological science and explanation for rare disorders to a field that is profoundly altering health care for everyone. This thoroughly updated new edition of _Human Genetics: The Basics_ provides a concise background of gene structure and function through the lens of real examples, from families living with inherited diseases to population-wide efforts in which millions of average people are learning about their genetic selves. The book raises compelling issues concerning: • The role of (...) genes in maintaining health and explaining sickness • Genetic testing, gene therapy, and genome editing • The common ancestry of all humanity and how we are affecting our future. Written in an engaging, narrative manner, this concise introduction is an ideal starting point for anyone who wants to know more about genes, DNA, genomes, and the genetic ties that bind us all.

The topic of homonymy, especially the variety of homonymy that has gone under the title, “focal meaning,” is of fundamental importance to large portions of Aristotle’s work-not to mention its central place in the ongoing controversies between Aristotle and Plato. It is quite astonishing, therefore, that the topic should have gone so long without a book-length treatment. And it is all the more gratifying that the new book on homonymy by Christopher Shields should be so comprehensive, and of such uniformly (...) high quality.’ Everyone who cares about Aristotle will be in his debt. Shields’s book falls into two parts. In the first, he is concerned to lay out the basic structure of Aristotle’s views about homonymy; in the second part, we are led through the various applications of the idea, to the analysis of friendship, for example, the homonymy of the body, the account of goodness and, not least, the homonymy of being. Shields’s book brings out well how the topic of homonymy weaves in and out of the fabric of Aristotle’s thinking in a variety of areas. I will resist the temptation to follow Shields through these various subject-matters, and instead take up essentially two topics. First, (I), the basic outline of Aristotle’s notion of homonymy, more or less independently of its different applications (here, I follow Shields’s example in the first half of his book). Thereafter, I discuss a single application: the homonymy of being (this is the subject of Shields’s last and longest chapter). Here, I will be interested (II) in how homonymy relates to the theory of the categories; and (III) in the application of homonymy to the analysis of substance in the Metaphysics. (shrink)

Created as a poetic and visual journey, Touchless Automatic Wonder spans twenty-five years and four continents. These striking photographs capture “found text”: the sometimes mysterious, occasionally humorous, often cryptic presence of words in the everyday landscape. In Koch’s lyrical sequencing, the images reveal obscure and eccentric voices in their various and distinctive roles on the daily stage of the world around us. This intriguing approach at the intersection of language, image, and the social landscape will appeal to readers interested in (...) contemporary art and photography, popular culture, and conceptual concerns both literary and visual.
