This collection argues that scientific progress is driven by an essential tension between the tradition of normal science and the disruptive force of scientific revolution. Kuhn posits that the scientific community operates within established paradigms, which guide research and problem-solving during periods of "normal science." However, the accumulation of anomalies can eventually lead to a crisis, prompting a shift to a new, incommensurable paradigm through a scientific revolution.
The book examines how these paradigm shifts occur, challenging the notion of linear, cumulative scientific advancement. Readers gain insight into the dynamic interplay between adherence to established scientific frameworks and the radical changes that redefine scientific understanding, demonstrating that science's truth-seeking is embedded within these distinct phases of tradition and change.
Key concepts
- Normal Science — A period of scientific practice characterized by research conducted within an accepted scientific paradigm.
- Paradigm — The set of theories, methods, and assumptions that guide scientific inquiry within a particular field.
- Anomalies — Experimental results or observations that contradict the prevailing scientific paradigm.
- Scientific Revolution — A period of fundamental change in scientific understanding, involving the overthrow of an old paradigm and the establishment of a new one.
- Incommensurability — The idea that competing scientific paradigms cannot be directly compared or translated into one another.
