The Intelligibility of Kuhn’s Incommensurable Paradigms
Kuhn distinguishes two meanings for ‘paradigm’: in a narrow sense, (1) the examples a discipline uses to articulate its assumptions that set the template for solving puzzles that arise in the discipline during a period of normal science, and in a broad sense, (2) the key theories, instruments, values, and metaphysical assumptions that are made prior to puzzle-solving which constitute the disciplinary matrix of normal science. Count two paradigms ‘incommensurable’ when the new paradigm is a radical alteration of the matrix of measurements, observations, and language adopted by the scientific community not for good reasons but by a non-rational kind of religious conversion to a new world that is different than, and discontinuous with, the one represented by the former paradigm....
