What is life? For four centuries, it has been believed that the only possible scientific approach to this question proceeds from the Cartesian metaphor -- organism as machine. Therefore, organisms are to be studied and characterized the same way "machines" are; the same way any inorganic system is. Robert Rosen argues that such a view is neither necessary nor sufficient to answer the question. He asserts that life is not a specialization of mechanism, but rather a sweeping generalization of it. (...) Above all, Rosen argues that renouncing mechanism does not mean abandoning science. A radical alternative is proposed, drawn equally from experience in biology, physics, and mathematics; an alternative which draws attention to a new class of complex systems, which are radically different from mechanism.

The formal systems of logic have ordinarily been regarded as independent of biology, but recent developments in evolutionary theory suggest that biology and logic may be intimately interrelated. In this book, William Cooper outlines a theory of rationality in which logical law emerges as an intrinsic aspect of evolutionary biology. This biological perspective on logic, though at present unorthodox, could change traditional ideas about the reasoning process. Cooper examines the connections between logic and evolutionary biology and illustrates how logical rules (...) are derived directly from evolutionary principles, and therefore have no independent status of their own. Laws of decision theory, utility theory, induction, and deduction are reinterpreted as natural consequences of evolutionary processes. Cooper's connection of logical law to evolutionary theory ultimately results in a unified foundation for an evolutionary science of reason. It will be of interest to professionals and students of philosophy of science, logic, evolutionary theory, and cognitive science. (shrink)

"Dissanayake argues that art was central to human evolutionary adaptation and that the aesthetic faculty is a basic psychological component of every human being. In her view, art is intimately linked to the origins of religious practices and to ceremonies of birth, death, transition, and transcendence. Drawing on her years in Sri Lanka, Nigeria, and Papua New Guinea, she gives examples of painting, song, dance, and drama as behaviors that enable participants to grasp and reinforce what is important to their (...) cognitive world." --Publishers Weekly "A wide-ranging essay on the place of art in human evolution and in the future, at once learned and spirited."--Howard Gardner, Harvard University "Ellen Dissanayake's book is the most forceful rejoinder I've read so far to the trivializing pessimism of postmodernist art theory."--Kenneth Baker,San Francisco Chronicle "Affirm[s] the idea that art is for life's sake, for the fulfillment of fundamental human needs, and for human survival.... She gives us a coherent rationale for funding broadly based arts programs."--Art Therapy "Homo Aestheticusoffers a wealth of original and critical thinking. It will inform and irritate specialist, student, and lay reader alike."--American Anthropologist "Homo Aestheticus calls for a counterrevolution in our thinking about art. It is timely, provocative, and immensely valuable."--Philosophy and Literature. (shrink)

Metaphysicians speak of laws of nature in terms of necessity and universality; scientists, in terms of symmetry and invariance. In this book van Fraassen argues that no metaphysical account of laws can succeed. He analyzes and rejects the arguments that there are laws of nature, or that we must believe there are, and argues that we should disregard the idea of law as an adequate clue to science. After exploring what this means for general epistemology, the author develops the empiricist (...) view of science as a construction of models to represent the phenomena. (shrink)

I want to explore four different exercises of interpretation: (1) the interpretation of texts (or hermeneutics), (2) the interpretation of people (otherwise known as "attribution" psychology, or cognitive or intentional psychology), (3) the interpretation of other artifacts (which I shall call artifact hermeneutics), (4) the interpretation of organism design in evolutionary biology--the controversial interpretive activity known as adaptationism.

On this tour of the universe of signs, Jesper Hoffmeyer travels back to the Big Bang, visits the tiniest places deep within cells, and ends his journey with us - complex organisms capable of speech and reason. He shows that life at its most basic depends on the survival of messages written in the code of DNA molecules, and on the tiny cell - the fertilized egg - that must interpret the message and from it construct an organism. What propels (...) this journey is Hoffmeyer's attempt to discover how nature could come to mean something to someone; indeed, how "something" could become "someone." How could a biological self become a semiotic self? (shrink)

Combining ideas from philosophy, artificial intelligence, and neurobiology, Daniel Dennett leads the reader on a fascinating journey of inquiry, exploring such intriguing possibilities as: Can any of us really know what is going on in someone else's mind? What distinguishes the human mind from the minds of animals, especially those capable of complex behavior? If such animals, for instance, were magically given the power of language, would their communities evolve an intelligence as subtly discriminating as ours? Will robots, once they (...) have been endowed with sensory systems like those that provide us with experience, ever exhibit the particular traits long thought to distinguish the human mind, including the ability to think about thinking? Dennett addresses these questions from an evolutionary perspective. Beginning with the macromolecules of DNA and RNA, the author shows how, step-by-step, animal life moved from the simple ability to respond to frequently recurring environmental conditions to much more powerful ways of beating the odds, ways of using patterns of past experience to predict the future in never-before-encountered situations. Whether talking about robots whose video-camera ”eyes” give us the powerful illusion that ”there is somebody in there” or asking us to consider whether spiders are just tiny robots mindlessly spinning their webs of elegant design, Dennett is a master at finding and posing questions sure to stimulate and even disturb.
