According to Kuhn a (Kuhnian) paradigm shift is a fundamental direction change in science. Caused by doubt.
Kuhn 'softened' his original insights in such a way that they only concerned 'science'. Kuhnian paradigm shifts are shifts INSIDE the main body of science, and don't change life very much (unless life itself became scientific, rational ...).
Kuhn probably did so, because he enjoyed being a famous professor with a lot of priviliges, and had no intention at all to attack science itself as religion.
Thomas Kuhn
Thomas Kuhn was most famous for writing "The Structure of Scientific Revolutions" in 1962, which introduced the idea of "paradigm shifts" as an alternative idea to linear progression.
Thomas Kuhn, an eminent historian and philosopher of science, is known for calling the process of replacing one paradigm with another a "scientific revolution" in his book "The Structure of Scientific Revolutions." Kuhn's work has had a significant impact on the philosophy of science and our understanding of how scientific knowledge changes over time.
Kuhn believed that science progresses through shifts in paradigms, where accepted beliefs change dramatically, while Popper argued that science advances through falsification of theories and continuous testing. Kuhn emphasized the importance of consensus and normal science within a paradigm, while Popper focused on the critical testing of hypotheses to improve scientific knowledge.
Thomas Kuhn defined normal science as the day-to-day work conducted by scientists within a particular scientific paradigm. This work involves solving puzzles and anomalies within the existing framework of the paradigm through routine and systematic experimentation and observation. Normal science aims to elaborate and refine the existing paradigm rather than challenge its fundamental assumptions.
Quite simply put: Another paradigm. Nietzsche said something to this effect along the lines of a tyrannous morality is only replaced by a tyrannous morality, and I am sure Kuhn has answered this somewhere in his writing.
Thomas Kuhn 1922-1996 was an American philosopher who introduced cultural relativism after he discovered that the ancient physics of someone like Plato wasn't wrong but just a description of a completely different perception of reality. Such perceptions he called 'paradigms' Kuhn didnot realize (?) that 'rational science' is a paradigm itself, and that made his 'thoughts about paradigms inconsistent and confusing. Thomas Kuhn attacked the western paradigm from within, and that way did not challenge the basics. Like swimming around in a swimming pool and filtering the water.
The main difference between the philosophies of Kuhn and Popper is their views on how scientific progress occurs. Kuhn believed that science advances through paradigm shifts, where old theories are replaced by new ones, while Popper argued that science progresses through falsification, where theories are tested and potentially proven wrong.
. . .was not linear but by paradigm shifts (.paradigm definition from Merriam-Webster )a philosophical and theoretical framework of a scientific school or discipline within which theories, laws, and generalizations and the experiments performed in support of them are formulated ; broadly : a philosophical or theoretical framework of any kind.
Heinrich Kuhn has written: 'Heinrich Kuhn'
Popper's theory of scientific revolutions emphasizes falsifiability and the importance of testing hypotheses through experimentation. Kuhn's theory, on the other hand, focuses on paradigm shifts and the idea that scientific progress occurs through revolutions in thought rather than incremental changes.
Thomas Kuhn did not discover anything during The Scientific Revolution (1500-1700s, or Copernicus-Newton basically). He lived during the twentieth century and was most influential with his work The Structure of Scientific Revolutions (1962) and his radical, sociological take on the philosophy of science. He did write about scientific revolutions and determined that science follows a predictable cycle of what he called crisis and normal science.
