Philosophy of science is the branch of philosophy concerned with the foundations, methods, and implications of science. Amongst its central questions are the difference between science and non-science, the reliability of scientific theories, and the ultimate purpose and meaning of science as a human endeavour. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of scientific practice, and overlaps with metaphysics, ontology, logic, and epistemology, for example, when it explores the relationship between science and the concept of truth. Philosophy of science is both a theoretical and empirical discipline, relying on philosophical theorising as well as meta-studies of scientific practice. Ethical issues such as bioethics and scientific misconduct are often considered ethics or science studies rather than the philosophy of science.
Isidore Auguste Marie François Xavier Comte was a French philosopher, mathematician and writer who formulated the doctrine of positivism. He is often regarded as the first philosopher of science in the modern sense of the term. Comte's ideas were also fundamental to the development of sociology, with him inventing the very term and treating the discipline as the crowning achievement of the sciences.
Herbert Spencer was an English polymath active as a philosopher, psychologist, biologist, sociologist, and anthropologist. Spencer originated the expression "survival of the fittest", which he coined in Principles of Biology (1864) after reading Charles Darwin's 1859 book On the Origin of Species. The term strongly suggests natural selection, yet Spencer saw evolution as extending into realms of sociology and ethics, so he also supported Lamarckism.
In jurisprudence and legal philosophy, legal positivism is the theory that the existence of the law and its content depend on social facts, such as acts of legislation, judicial decisions, and customs, rather than on morality. This contrasts with natural law theory, which holds that law is necessarily connected to morality in such a way that any law that contradicts morality lacks legal validity.
Postpositivism or postempiricism is a metatheoretical stance that critiques and amends positivism and has impacted theories and practices across philosophy, social sciences, and various models of scientific inquiry. While positivists emphasize independence between the researcher and the researched person, postpositivists argue that theories, hypotheses, background knowledge and values of the researcher can influence what is observed. Postpositivists pursue objectivity by recognizing the possible effects of biases. While positivists emphasize quantitative methods, postpositivists consider both quantitative and qualitative methods to be valid approaches.
Sociology as a scholarly discipline emerged, primarily out of Enlightenment thought, as a positivist science of society shortly after the French Revolution. Its genesis owed to various key movements in the philosophy of science and the philosophy of knowledge, arising in reaction to such issues as modernity, capitalism, urbanization, rationalization, secularization, colonization and imperialism.
In social science, antipositivism is a theoretical stance which proposes that the social realm cannot be studied with the methods of investigation utilized within the natural sciences, and that investigation of the social realm requires a different epistemology. Fundamental to that antipositivist epistemology is the belief that the concepts and language researchers use in their research shape their perceptions of the social world they are investigating and seeking to define.
Philosophy in this sense means how social science integrates with other related scientific disciplines, which implies a rigorous, systematic endeavor to build and organize knowledge relevant to the interaction between individual people and their wider social involvement.
Positivism is a philosophical school that holds that all genuine knowledge is either true by definition or positive – meaning a posteriori facts derived by reason and logic from sensory experience. Other ways of knowing, such as intuition, introspection, or religious faith, are rejected or considered meaningless.
The history of the social sciences has its origins in the common stock of Western philosophy and shares various precursors, but began most intentionally in the early 18th century with the positivist philosophy of science. Since the mid-20th century, the term "social science" has come to refer more generally, not just to sociology but to all those disciplines which analyze society and culture, from anthropology to psychology to media studies.
The law of three stages is an idea developed by Auguste Comte in his work The Course in Positive Philosophy. It states that society as a whole, and each particular science, develops through three mentally conceived stages: (1) the theological stage, (2) the metaphysical stage, and (3) the positive stage.
Charles Abram Ellwood was an American sociologist who was professor of sociology at University of Missouri-Columbia and Duke University. He has been described as one of the leading American sociologists of the interwar period, studying intolerance, communication and revolutions and using many multidisciplinary methods.
Giorgio Del Vecchio was a prominent Italian legal philosopher of the early 20th century. Among others he influenced the theories of Norberto Bobbio. He is famous for his book Justice.
Religion of Humanity is a secular religion created by Auguste Comte (1798–1857), the founder of positivist philosophy. Adherents of this religion have built chapels of Humanity in France and Brazil.
Simon Nelson Patten was an American economist and the chair of the Wharton School of Business at the University of Pennsylvania. Patten was one of the first economists to posit a shift from an 'economics of scarcity' to an 'economics of abundance'; that is, he believed that soon there would be enough wealth to satisfy people's basic needs and that the economy would shift from an emphasis on production to consumption.
Sociology is the scientific study of human society that focuses on society, human social behavior, patterns of social relationships, social interaction, and aspects of culture associated with everyday life. Regarded as a part of both the social sciences and humanities, sociology uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order and social change. Sociological subject matter ranges from micro-level analyses of individual interaction and agency to macro-level analyses of social systems and social structure. Applied sociological research may be applied directly to social policy and welfare, whereas theoretical approaches may focus on the understanding of social processes and phenomenological method.
A General View of Positivism is a 1848 book by the French philosopher Auguste Comte, first published in English in 1865. A founding text in the development of positivism and the discipline of sociology, the work provides a revised and full account of the theory Comte presented earlier in his multi-part The Course in Positive Philosophy (1830–1842). Comte outlines the epistemological view of positivism, provides an account of the manner by which sociology should be performed, and describes his law of three stages.
Knowledge and Human Interests is a 1968 book by the German philosopher Jürgen Habermas, in which the author discusses the development of the modern natural and human sciences. He criticizes Sigmund Freud, arguing that psychoanalysis is a branch of the humanities rather than a science, and provides a critique of the philosopher Friedrich Nietzsche.
Gustav Ratzenhofer was an Austrian military officer, philosopher and sociologist. He also wrote under the pseudonym Gustav Renehr.
The hierarchy of the sciences is a theory formulated by Auguste Comte in the 19th century. This theory states that science develops over time beginning with the simplest and most general scientific discipline, astronomy, which is the first to reach the "positive stage". As one moves up the "hierarchy", this theory further states that sciences become more complex and less general, and that they will reach the positive stage later. Disciplines further up the hierarchy are said to depend more on the developments of their predecessors; the highest discipline on the hierarchy are the social sciences. According to this theory, there are higher levels of consensus and faster rates of advancement in physics and other natural sciences than there are in the social sciences.
