A Philosophical Essay On Molecular Structure

Molecular structure is something taken for granted by chemists. Together with elements, atoms and bonds, it is the basis for talking about organic chemistry. Given molecular structure, chemists are engaged in designing molecules and performing chemical syntheses of a variety of compounds. The structure-activity relationship in drug research is an illuminating example. However, of course, nobody has ever seen molecular structure. Molecules are too small to see. Moreover, molecular structure cannot be derived a priori from fundamental principles of quantum mechanics. This book explores why this is the case. Is what chemists take to be molecular structure real? This book addresses head-on the ontological, as well as epistemological, grounds of one of the most fundamental concepts of chemistry. Its arguments are grounded on the learning of the history of chemistry, philosophy (Kant in particular), quantum mechanics and organic chemistry. The book will serve as a good introduction to the philosophy of chemistry.

Of Minds and Molecules is the first anthology devoted exclusively to work in the philosophy of chemistry. The essays, written by both chemists and philosophers, adopt distinctive philosophical perspectives on chemistry and collectively offer both a conceptualization of and a justification for this emerging field.

"A philosophical statement whose explicit intention is to sweep away as both false and dangerous the 'animist' conception of man that has dominated virtually all Western world views from those of primitive cultures to those of dialectical materialists. Monod bases his argument on the evidence of modern biology, which shows, indisputably, that man is the product of chance genetic mutation. He draws upon what we now know about genetic structure (and on what we can theorize) to suggest an entirely new way of looking at ourselves. He argues that objective scientific knowledge, the only knowledge we can rely on, denies the concepts of destiny or evolutionary purpose that underlie traditional philosophies; and he contends that the persistence of those concepts is responsible for the intensifying schizophrenia of a world that accepts, and lives by, the fruits of science while refusing to face its momentous moral implications"--From publisher description.

The two volumes of Philosophical Essays bring together the most important essays written by one of the world's foremost philosophers of language. Scott Soames has selected thirty-one essays spanning nearly three decades of thinking about linguistic meaning and the philosophical significance of language. A judicious collection of old and new, these volumes include sixteen essays published in the 1980s and 1990s, nine published since 2000, and six new essays. The essays in Volume 1 investigate what linguistic meaning is; how the meaning of a sentence is related to the use we make of it; what we should expect from empirical theories of the meaning of the languages we speak; and how a sound theoretical grasp of the intricate relationship between meaning and use can improve the interpretation of legal texts. The essays in Volume 2 illustrate the significance of linguistic concerns for a broad range of philosophical topics--including the relationship between language and thought; the objects of belief, assertion, and other propositional attitudes; the distinction between metaphysical and epistemic possibility; the nature of necessity, actuality, and possible worlds; the necessary a posteriori and the contingent a priori; truth, vagueness, and partial definition; and skepticism about meaning and mind. The two volumes of Philosophical Essays are essential for anyone working on the philosophy of language.

Philip Kitcher is one of the leading figures in the philosophy of science today. Here he collects, for the first time, many of his published articles on the philosophy of biology, spanning from the mid-1980's to the present. The book's title refers to Gregor Mendel, an Augustinian monk who was one of the first scientists to develop a theory of heredity. Mendel's work has been deeply influential to our understanding of our selves and our world, just as the study of genetics today will have a profound and long-term impact on future scientific research. Kitcher's articles cover a broad range of topics with similar philosophical and social significance: sociobiology, evolutionary psychology, species, race, altruism, genetic determinism, and the rebirth of creationism in Intelligent Design. Kitcher's work on the intersection of biology and the philosophy of science is both unprecedented and wide-ranging, and will appeal not only to philosophers of science, but to scholars and students across disciplines.

Despite the transformation in biological practice and theory brought about by discoveries in molecular biology, until recently philosophy of biology continued to focus on evolutionary biology. When the Human Genome Project got underway in the late 1980s and early 1990s, philosophers of biology—unlike historians and social scientists—had little to add to the debate. In this landmark collection of essays, Sahotra Sarkar broadens the scope of current discussions of the philosophy of biology, viewing molecular biology as a unifying perspective on life that complements that of evolutionary biology. His focus is on molecular biology, but the overriding question behind these papers is what molecular biology contributes to all traditional areas of biological research.Molecular biology—described with some foresight in a 1938 Rockefeller Foundation report as a branch of science in which "delicate modern techniques are being used to investigate ever more minute details"—and its modeling strategies apparently argue in favor of physical reductionism. Sarkar's first three chapters explore reductionism—defending it, but cautioning that reduction to molecular interactions is not necessarily a reduction to genetics (and does not support the claims of either heriditarianism or environmentalism). The next sections of the book discuss function, exploring how functional explanations pose a problem for reductionism; the informational interpretation of biology and how it interacts with reductionism; and the tension between the unifying framework of molecular biology and the received framework of evolutionary theory. The concluding chapter is an essay in the emerging field of developmental evolution, exploring what molecular biology may contribute to the transformation of evolutionary theory as evolutionary theory takes into account morphogenetic development.

From the Atom to Living Systems represents an original historico-epistemological approach to follow the passage, in the microscopic analysis of reality, from the atomic to the molecular to the macromolecular levels and then to the threshold of life itself. Naturally, some parts of this journey have been developed in other works, some highly specialized and others of a more general nature. However, although this journey has often been traced in specialized scientific detail, the philosophical implications of the journey have not been discussed to any satisfactory degree. This scientific journey does have important philosophical consequences that constitute an integral part of this book, which is framed within the perspective of systems science and the so-called sciences of complexity, which are areas fundamental to 21st century science. In fact, the possibility of studying and understanding the material world through levels of complexity opens a great philosophical space that proposes to provide systemic and complex explanations, rather than reductive accounts that pretend to explain all phenomena through the interactions of elementary particles while considering all phenomena implicit and deterministic. The systemic and complex approach implies substituting unique bottom-up explanations, which move exclusively from the microscopically simple to the macroscopically complex, with a series of explanations that are horizontal within planes of complexity, vertically bottom up between various levels of complexity, vertically top-down, as well as circular in a manner that renders all levels of reality and the disciplines that study them as both autonomous and interconnected.
