Philosophy of Science — Key Points

No source links recorded for this answer.

1. Central questions - What distinguishes science from non-science? (Demarcation problem) - How do scientific theories explain and predict phenomena? - What is the nature of scientific reasoning (induction, deduction, abduction)? - How do observation and theory interact (theory-ladenness of observation)? - What is the status of scientific knowledge (realism vs. anti-realism)? 2. Major positions - Scientific Realism: Best scientific theories approximately truthfully describe unobservable entities (Putnam, Boyd). - Instrumentalism/Anti-Realism: Theories are tools for prediction, not necessarily true descriptions (van Fraassen). - Constructivism and Social Epistemology: Scientific knowledge is shaped by social processes, values, and institutions (Kuhn, Latour). - Structuralism and Model-Based Views: Science advances via models and structures rather than literal true statements (Suppe, Cartwright). 3. Methodology and reasoning - Induction: Generalizing from observations—problem of justifying induction (Hume). - Falsificationism: Popper’s idea that theories are scientific if falsifiable; emphasizes bold conjectures and refutations. - Bayesianism: Probabilistic updating of belief based on evidence. - Lakatos’ Research Programmes: Science progresses through competing research programmes with heuristics and protective belts. 4. Explanation and laws - Covering-law model: Explanations subsume phenomena under general laws (Hempel). - Causal/mechanistic accounts: Explanations cite causes or mechanisms producing phenomena (Salmon, Craver). - Pragmatic and pluralist views: Multiple types of explanation depending on context. 5. Values, objectivity, and ethics - Science aims for objectivity, but choices about methods, significance, and application involve epistemic and non-epistemic values. - Responsible research requires transparency, reproducibility, and ethical reflection. 6. Contemporary issues - Replication crisis and reliability of findings. - Role of models, simulations, and big data. - Science policy, public trust, and science communication. Further reading (concise) - Peter Godfrey-Smith, Theory and Reality (2003) - Karl Popper, The Logic of Scientific Discovery (1959) - Thomas Kuhn, The Structure of Scientific Revolutions (1962) - Bas van Fraassen, The Scientific Image (1980) If you want, I can explain any one of these points in more detail or compare specific positions (e.g., realism vs. van Fraassen).

Constructivism and Social Epistemology

No source links recorded for this answer.

Constructivism and social epistemology hold that scientific knowledge is not produced in isolation by lone observers discovering neutral facts, but is shaped fundamentally by social processes, values, and institutions. Key claims: - Knowledge as constructed: Scientific facts, theories, and classifications arise through human practices—experiments, instruments, language, and interpretive frameworks—rather than being simple mirrors of an independent nature. What counts as a convincing observation or a legitimate theory depends on shared methods and background assumptions (Kuhn: paradigms; Latour: laboratory practices and network-building). - Role of communities and institutions: Scientific consensus is achieved through social mechanisms—peer review, training, funding, institutional norms, conferences—so scientific change often reflects shifts in community standards, interests, or power relations as much as empirical recalcitrance. Kuhn’s “scientific revolutions” emphasize paradigm shifts in which a community adopts new standards; Latour analyzes how networks of actors and instruments stabilize facts. - Values and interests matter: Non-epistemic values (social, political, economic) can influence what questions are asked, which methods are privileged, and which results are pursued or accepted. Constructivists warn that scientific practice is value-laden and context-sensitive. - Not radical relativism: Most contemporary constructivists and social epistemologists do not deny that empirical constraints exist; rather they stress that empirical data are theory-laden and that acceptance of claims depends on social validation. Science’s authority comes from the robustness of social processes that produce reliable knowledge, not from a purely objective, context-free gaze. Key references: Thomas Kuhn, The Structure of Scientific Revolutions (1962); Bruno Latour and Steve Woolgar, Laboratory Life (1979); Helen Longino, Science as Social Knowledge (1990).
