Logical positivism, later called logical empiricism, and both of which together are also known as neopositivism, is a movement whose central thesis is the verification principle. This theory of knowledge asserts that only statements verifiable through direct observation or logical proof are meaningful in terms of conveying truth value, information or factual content. Starting in the late 1920s, groups of philosophers, scientists, and mathematicians formed the Berlin Circle and the Vienna Circle, which, in these two cities, would propound the ideas of logical positivism.
The teleological argument is an argument for the existence of God or, more generally, that complex functionality in the natural world which looks designed is evidence of an intelligent creator.
Alvin Carl Plantinga is an American analytic philosopher who works primarily in the fields of philosophy of religion, epistemology, and logic.
The Vienna Circle of logical empiricism was a group of elite philosophers and scientists drawn from the natural and social sciences, logic and mathematics who met regularly from 1924 to 1936 at the University of Vienna, chaired by Moritz Schlick. The Vienna Circle had a profound influence on 20th-century philosophy, especially philosophy of science and analytic philosophy.
Richard Charles Lewontin was an American evolutionary biologist, mathematician, geneticist, and social commentator. A leader in developing the mathematical basis of population genetics and evolutionary theory, he applied techniques from molecular biology, such as gel electrophoresis, to questions of genetic variation and evolution.
William Wimsatt is an American author and political activist. He is the founder of the League of Young Voters, co-founder of Generational Alliance, and the author of three books including Bomb the Suburbs, No More Prisons, and Please Don't Bomb The Suburbs.
Organicism is the philosophical position that states that the universe and its various parts ought to be considered alive and naturally ordered, much like a living organism. Vital to the position is the idea that organicistic elements are not dormant "things" per se but rather dynamic components in a comprehensive system that is, as a whole, everchanging. Organicism is related to but remains distinct from holism insofar as it prefigures holism; while the latter concept is applied more broadly to universal part-whole interconnections such as in anthropology and sociology, the former is traditionally applied only in philosophy and biology. Furthermore, organicism is incongruous with reductionism because of organicism's consideration of "both bottom-up and top-down causation." Regarded as a fundamental tenet in natural philosophy, organicism has remained a vital current in modern thought, alongside both reductionism and mechanism, that has guided scientific inquiry since the early 17th century.
The philosophy of biology is a subfield of philosophy of science, which deals with epistemological, metaphysical, and ethical issues in the biological and biomedical sciences. Although philosophers of science and philosophers generally have long been interested in biology, philosophy of biology only emerged as an independent field of philosophy in the 1960s and 1970s, associated with the research of David Hull. Philosophers of science then began paying increasing attention to biology, from the rise of Neodarwinism in the 1930s and 1940s to the discovery of the structure of DNA in 1953 to more recent advances in genetic engineering. Other key ideas include the reduction of all life processes to biochemical reactions, and the incorporation of psychology into a broader neuroscience.
Adaptationism is the Darwinian view that many physical and psychological traits of organisms are evolved adaptations. Pan-adaptationism is the strong form of this, deriving from the early 20th century modern synthesis, that all traits are adaptations, a view now shared by only a few biologists.
The deductive-nomological model of scientific explanation, also known as Hempel's model, the Hempel–Oppenheim model, the Popper–Hempel model, or the covering law model, is a formal view of scientifically answering questions asking, "Why...?". The DN model poses scientific explanation as a deductive structure, one where truth of its premises entails truth of its conclusion, hinged on accurate prediction or postdiction of the phenomenon to be explained.
William Bechtel is a professor of philosophy in the Department of Philosophy and the Science Studies Program at the University of California, San Diego. He was a professor of philosophy at Washington University in St. Louis from 1994 until 2002. Bechtel was also the chair of the Philosophy Department from 1999 until 2002 and was heavily involved with the Philosophy-Psychology-Neuroscience program, serving at different times as Assistant Director and Director. Before that, he was at Georgia State. Bechtel earned his PhD from the University of Chicago and his BA from Kenyon College.
David Burton Wake was an American herpetologist. He was professor of integrative biology and Director and curator of herpetology of the Museum of Vertebrate Zoology at the University of California, Berkeley. Wake is known for his work on the biology and evolution of salamanders as well as general issues of vertebrate evolutionary biology. He has served as president of the Society for the Study of Evolution, the American Society of Naturalists, and American Society of Zoologists. He was a member of the American Association for the Advancement of Science, the Linnean Society of London, the American Academy of Arts and Sciences, the American Philosophical Society, and in 1998 was elected into the National Academy of Sciences. He was awarded the 2006 Leidy Award from the Academy of Natural Sciences of Philadelphia.
Alexander Rosenberg is an American philosopher and novelist. He is the R. Taylor Cole Professor of Philosophy at Duke University, well known for contributions to philosophy of biology and philosophy of economics.
William G. Lycan is an American philosopher and professor emeritus at University of North Carolina at Chapel Hill, where he was formerly the William Rand Kenan, Jr. Distinguished Professor. Since 2011, Lycan is also distinguished visiting professor of philosophy at the University of Connecticut, where he continues to research, teach, and advise graduate students.
Errol Eustace Harris, sometimes cited as E. E. Harris, was a South African philosopher. His work focused on developing a systematic and coherent account of the logic, metaphysics, and epistemology implicit in contemporary understanding of the world. Harris held that, in conjunction with empirical science, the Western philosophical tradition, in its commitment to the ideal of reason, contains the resources necessary to accomplish this end. He celebrated his 100th birthday in 2008.
James R. Griesemer is an American professor of philosophy at the University of California, Davis in Davis, California specializing in philosophy of biology.
Sahotra Sarkar is an Indian-American professor at the University of Texas at Austin, specializing in the philosophy of biology.
William A. Wimsatt was professor of Zoology and Chairman of the Department of Zoology at Cornell University. From 1945 until 1960, Wimsatt taught courses in histology and embryology in the College of Arts and Sciences and also in the New York State College of Veterinary Medicine. He was well known for his pioneering research on the interrelationships of hibernation and reproduction and the biology of bats.
Teleology in biology is the use of the language of goal-directedness in accounts of evolutionary adaptation, which some biologists and philosophers of science find problematic. The term teleonomy has also been proposed. Before Darwin, organisms were seen as existing because God had designed and created them; their features such as eyes were taken by natural theology to have been made to enable them to carry out their functions, such as seeing. Evolutionary biologists often use similar teleological formulations that invoke purpose, but these imply natural selection rather than actual goals, whether conscious or not. Biologists and religious thinkers held that evolution itself was somehow goal-directed (orthogenesis), and in vitalist versions, driven by a purposeful life force. With evolution working by natural selection acting on inherited variation, the use of teleology in biology has attracted criticism, and attempts have been made to teach students to avoid teleological language.
Teleology is a philosophical idea where natural phenomena are explained in terms of the purpose they serve, rather than the cause by which they arise.
