Examples of Paradigm Shifts in The Natural Sciences

Some of the "classical cases" of Kuhnian paradigm shifts in science are:

  • The transition in cosmology from a Ptolemaic cosmology to a Copernican one.
  • The transition in optics from geometrical optics to physical optics.
  • The transition in mechanics from Aristotelian mechanics to classical mechanics.
  • The acceptance of the theory of biogenesis, that all life comes from life, as opposed to the theory of spontaneous generation, which began in the 17th century and was not complete until the 19th century with Pasteur.
  • The acceptance of the work of Andreas Vesalius, whose work De humani corporis fabrica corrected the numerous errors in the previously-held system created by Galen.
  • The transition between the Maxwellian Electromagnetic worldview and the Einsteinian Relativistic worldview.
  • The transition between the worldview of Newtonian physics and the Einsteinian Relativistic worldview.
  • The development of quantum mechanics, which replaced classical mechanics at microscopic scales.
  • The acceptance of plate tectonics as the explanation for large-scale geologic changes.
  • The development of absolute dating.
  • The acceptance of Lavoisier's theory of chemical reactions and combustion in place of phlogiston theory, known as the Chemical Revolution.
  • The acceptance of Mendelian inheritance, as opposed to pangenesis in the early 20th century

    “There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.”
    —Bernard Mandeville (1670–1733)

    “There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.”
    —Bernard Mandeville (1670–1733)

    “As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
    —Thomas S. Kuhn (b. 1922)

    “The flattering, if arbitrary, label, First Lady of the Theatre, takes its toll. The demands are great, not only in energy but eventually in dramatic focus. It is difficult, if not impossible, for a star to occupy an inch of space without bursting seams, cramping everyone else’s style and unbalancing a play. No matter how self-effacing a famous player may be, he makes an entrance as a casual neighbor and the audience interest shifts to the house next door.”
    —Helen Hayes (1900–1993)

    “It would be one of the greatest triumphs of humanity, one of the most tangible liberations from the constraints of nature to which mankind is subject, if we could succeed in raising the responsible act of procreating children to the level of a deliberate and intentional activity and in freeing it from its entanglement with the necessary satisfaction of a natural need.”
    —Sigmund Freud (1856–1939)

    “All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.”
    —Georg Wilhelm Friedrich Hegel (1770–1831)
