Philosophy of science is a branch of philosophy concerned with the foundations, methods, assumptions, and implications of scientific inquiry. It examines how scientific knowledge is produced, how evidence supports theories, and what kinds of claims science can legitimately make about the world.
The field intersects closely with epistemology and addresses questions about explanation, objectivity, and the limits of scientific understanding.
Core idea
At its core, philosophy of science investigates how science works and what distinguishes scientific inquiry from other forms of investigation. It asks how observations, experiments, models, and theories contribute to knowledge and understanding.
Rather than advancing scientific theories themselves, philosophy of science analyzes their structure, justification, and scope.
Science and inquiry
Philosophy of science treats science as a form of inquiry aimed at explaining, predicting, and understanding phenomena. It examines the goals of scientific practice and the norms governing evidence, reasoning, and revision.
This analysis clarifies how science manages uncertainty and disagreement.
Evidence and confirmation
A central topic concerns how evidence supports scientific claims. Philosophers examine what counts as evidence, how evidential support should be assessed, and how competing theories are compared.
Issues arise when evidence underdetermines theory choice.
Explanation in science
Scientific inquiry often aims at explanation. Philosophy of science examines different kinds of scientific explanation, including causal, mechanistic, and statistical explanations.
Debates concern what explanations must provide in order to be satisfactory.
Models and idealization
Scientific models often involve simplification or idealization. Philosophy of science examines how models can generate understanding even when they are known to be inaccurate in detail.
This raises questions about representation, abstraction, and truth.
Laws and regularities
Philosophers of science analyze the role of laws in scientific explanation and prediction. Questions arise about whether laws describe necessary connections, stable regularities, or useful summaries.
These issues intersect with debates about causation and determinism.
Realism and anti-realism
One major debate concerns whether scientific theories describe reality as it is or merely provide useful instruments for prediction. Scientific realism holds that successful theories are at least approximately true, while anti-realist views emphasize empirical adequacy or usefulness.
This debate concerns the interpretation of truth in science.
Objectivity and values
Philosophy of science examines whether science is objective and value-neutral. While scientific methods aim at objectivity, choices about research questions, models, and interpretation may involve contextual or pragmatic values.
Clarifying this interaction helps distinguish epistemic standards from social influences.
Change and progress
Scientific knowledge changes over time. Philosophy of science investigates how scientific change should be understood, whether as cumulative improvement, conceptual transformation, or revision of frameworks.
This analysis addresses how progress is possible despite fallibility.
Limits of science
Not all questions are scientific. Philosophy of science examines the limits of scientific explanation and where scientific methods may be insufficient.
These limits do not diminish science but clarify its domain of applicability.
Status
Philosophy of science is an established field that provides critical reflection on scientific practice. Its role is to clarify how science produces knowledge, how its claims are justified, and how its limits should be understood.
