Criticism and the Growth of Knowledge

by Imre Lakatos

Summary

Imre Lakatos's "Criticism and the Growth of Knowledge" presents the central argument that scientific progress is driven by a "methodology of scientific research programmes." This methodology posits that theories are not abandoned immediately upon encountering falsifying evidence, but are instead protected by a "hard core" of basic assumptions that researchers are reluctant to discard. Progress occurs when a research programme can solve anomalies and make novel predictions, outperforming competing programmes.

The book, based on proceedings from a 1965 colloquium, lays out these ideas through critical debate. It examines how scientific knowledge grows not through simple falsification, but through a complex interplay of competing theories, their development, and the gradual modification or replacement of their auxiliary hypotheses in response to challenges. Readers learn about the dynamics of theory change within a scientific community.

Key concepts

  • Methodology of scientific research programmesA framework for understanding scientific progress where theories evolve through a protective hard core and auxiliary hypotheses.
  • Hard coreThe fundamental, protected assumptions of a scientific research programme that are resistant to falsification.
  • Auxiliary hypothesesAssumptions that can be modified or replaced to protect the hard core of a research programme when encountering contradictory evidence.
  • Scientific progressCharacterized by research programmes that can solve anomalies and generate novel predictions, thereby outperforming rival programmes.
