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.

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.

This compilation of twenty-six scientific papers and philosophical essays expands the mind-body problem of the French philosopher and mathematician René Descartes. We expose the nature consciousness; we discuss its origin and manifestations in living organisms. We distinguish it from life and elaborate on human existence on Earth. From there, we solve the ancient enigma posited by Epicurus, the Greek philosopher. In science, we take over Schrodinger’s works on the body’s entropy and use the research of the Japanese Nobel laureate Yoshinori Ohsumi to explain how non-living atoms transition to living molecules, Francis Crick’s faded dream that becomes reality. We delve into the living organisms to explain various losses of consciousness and awareness, including sleep, syncope, and death. We mainly focus on sleep to elucidate this mystery that no living organisms escape.

Robert Boyle (1627-1691) believed that a reductionist conception of the mechanical philosophy threatened the heuristic power and autonomy of chemistry as an experimental science. While some historical and philosophical scholars have examined his nuanced position, understanding the chemical philosophy he developed through his own experimental work is incredibly difficult even for experts in the field. In The Chemical Philosophy of Robert Boyle, Marina Paola Banchetti-Robino energetically explains Boyle's ideas in a whole new light and proposes that Boyle regarded chemical qualities as non-reducible dispositional and relational properties that emerge from, and supervene upon, the mechanistic structure of chymical atoms. Banchetti-Robino demonstrates that these ideas are implicit in Boyle's writing, making his philosophical contributions crucial to the fields of both philosophy and chemistry. The arguments presented are further strengthened by a detailed mereological analysis of Boylean chymical atoms as chemically elementary entities, which establishes the theory of wholes and parts that is most consistent with an emergentist conception of chemical properties. More generally, this book examines the way in which Boyle sought to accommodate his complex chemical philosophy within the framework of the 17th century mechanistic theory of matter. Banchetti-Robino conceptualizes Boyle's experimental work as a scientific research programme, in the Lakatosian sense, to better explain the positive and negative heuristic function of the mechanistic theory of matter within his chemical philosophy. The Chemical Philosophy of Robert Boyle actively engages with the contemporary and lively debates over the nature of Boyle's ideas about structural chemistry, fundamental mechanistic particles and properties, the explanatory power of subordinate causes, the complex relation between fundamental particles, natural kinds, and unified chemical wholes. The book is a rich historical account that begins with the dominant paradigms of 16th and 17th Century chemical philosophy and takes readers all the way through to the 21st Century.
