About this topic
Summary Sir Karl Popper (1902-1994) was an Austrian-born philosopher who for the most significant period of his career held a position at the London School of Economics.  Popper was a philosopher of science, who also made contributions in epistemology, philosophy of mind and social and political philosophy.  He argued that scientific theories are distinguished from non-scientific theories and pseudo-science by being falsifiable claims about the world.  Popper proposed a "solution" to the problem of induction by arguing that there is no need for induction in the scientific method.  The method of science is to propose conjectural theories which are then submitted to rigorous tests in the attempt to falsify them.  Theories which fail these tests are to be rejected.  Theories which survive attempts to refute them may be accepted tentatively, but are not proven to be true.  At best, they may be highly corroborated.  This "falsificationist" philosophy of science has a more general application beyond the method of the sciences.  The attempt to falsify a theory is an attempt to criticize the theory.  For Popper, criticism lies at the heart of rational thought, which he took to consist in the method of critical discussion and reflection.  The resulting general position is known as "critical rationalism".  Popper extended these ideas as well into the social and political realm.  He introduced the distinction between open and closed societies.  Open societies welcome and foster critical discussion and change whereas closed societies, which are usually tribal societies, are based on unchanging social custom and ritual.
Key works The classic statement of Popper's philosophy of science is The Logic of Scientific Discovery.  Perhaps the best introduction to his work is his collection of essays, Conjectures and Refutations.  Popper's social and political thought may be found in The Poverty of Historicism and The Open Society and its Enemies.  A good anthology of his writings has been edited by David Miller, Popper Selections.  A useful way into Popper's ideas is by way of his intellectual autobiography, Unended Quest, as is Bryan Magee's short book, Popper.  Alan Musgrave's Common Sense, Science and Scepticism presents a broadly Popperian introduction to epistemology.  David Miller's Critical Rationalism presents good discussion of many critical points that have been made against Popper's views.  Criticism and the Growth of Knowledge, edited by Imre Lakatos and Alan Musgrave, contains a number of important papers which bring Popper's views into contact with T.S. Kuhn's theory of science.  Wesley Salmon's 'Rational Prediction' is an important criticism of Popper's solution to the problem of induction.  See also Adolf Grunbaum's paper 'Is the method of bold conjectures and attempted refutations justifiably the method of science?'.
Introductions A good place to start is the entry in the Stanford Encyclopedia of Philosophy, Thornton 2008.  Alan Chalmers provides an introductory discussion in What is this thing called science?, chapters 4-6.  Gurol Irzik provides an overview in 'Critical Rationalism', and Alan Musgrave presents his interpretation of Popper's solution of the problem of induction in his paper 'How Popper (might have) solved the problem of induction'.

    Basic research or fundamental research is distinct from both pure and applied research, in that it is pure research with expected useful results. The existence of basic or fundamental research is problematic, at least for both inductivists and instrumentalists, but also for Popper. Assuming scientific research to be the search for explanatory conjectures and for refutations, and assuming technology to be the search of conjectures and some corroborations, we can easily place basic or fundamental research between science and technology as (...)

    Bacon's inductivist philosophy of science divides thinkers into the scientific and the prejudiced, using as a standard the up-to-date science textbook. Inductivists regard the history of science as progressing smoothly, from facts rather than from problems, to increasingly general theories, undisturbed by contending scientific schools. Conventionalists regard theories as pigeonholes for classifying facts; history of science is the development of increasingly simple theories, neither true nor false. Conventionalism is useless for reconstructing and weighing conflicts between schools, and overemphasizes science's internal (...)

    I. C. Jarvie interprets Popper's philosophy of science as a theory of the institution of science, explains how the social aspect of his theory developed, and suggests that an updated version of Popper's social theory should be used to study both scientific and nonscientific societies today. Although (1) Jarvie's description of the emergence of Popper's theory suffers because he takes no account Popper's research conducted before Logik der Forschung (1994), (2) his portrayal of Popper's framework overlooks important problems, and (3) (...)

    Dr Chaudhury is concerned to defend what is responsible and hopeful in contemporary ecological thinking, but to avoid the trap of denying that any positive contribution can be made by western science and technology. Critical rationalists do not need to agree with her suggestions and recommendations in order to welcome her positioning of environmental issues alongside the traditional human and political debates about freedom. The Indian perspective that informs this book is particularly impressive and interesting. David Miller Professor Mahasweta Chaudhury (...)

    It is often claimed that the conclusion of a deductively valid argument is contained in its premises. Popper refuted this claim when he showed that an empirical theory can be expected always to have logical consequences that transcend the current understanding of the theory. This implies that no formalisation of an empirical theory will enable the derivation of all its logical consequences. I call this result ‘Popper-incompleteness.’ This result appears to be consistent with the view of deductive reasoning as a (...)

    Die Frage der Erhaltung der Parität bei der Wechselwirkung von Elementarteilchen, der Vorschlag ihrer Verletzung, die experimentelle Bestätigung dieses Vorschlags und die daraus sich ergebenden Folgerungen, die zur Formulierung der mathematischen Struktur der schwachen Wechselwirkungen führten, sind die wichtigsten Entwicklungen in der Elementarteilchenphysik während der Periode von 1953 bis 1958. Vorliegender Aufsatz versucht die rationale Rekonstruktion dieser Periode und des Forschungsprogrammes, welches als eines der progressivsten Programme der modernen Physik angesehen wird.

    Popper emphasised both the problem-solving nature of human knowledge, and the need to criticise a scientific theory as strongly as possible. These aims seem to contradict each other, in that the former stresses the problems that motivate scientific theories while the one ignores the character of the problems that led to the formation of the theories against which the criticism is directed. A resolution is proposed in which problems as such are taken as prime in the search for knowledge, and (...)
