“once it has achieved the status of paradigm, a scientific theory is declared invalid only if an alternate candidate is available to take its place.”
― Thomas S. Kuhn, The Structure of Scientific Revolutions

“Once a first paradigm through which to view nature has been found, there is no such thing as research in the absence of any paradigm. To reject one paradigm without simultaneously substituting another is to reject science itself. That act reflects not on the paradigm but on the man. Inevitably he will be seen by his colleagues as “the carpenter who blames his tools.” The”

“When it can be said by any country in the world, my poor are happy, neither ignorance nor distress is to be found among them, my jails are empty of prisoners, my streets of beggars, the aged are not in want, the taxes are not oppressive, the rational world is my friend because I am the friend of happiness. When these things can be said, then may that country boast its constitution and government. Independence is my happiness, the world is my country and my religion is to do good.”
― Thomas Paine, Rights of Man

“Paradigms are not corrigible by normal science at all. Instead, as we have already seen, normal science ultimately leads only to the recognition of anomalies and to crises. And these are terminated, not by deliberation and interpretation, but by a relatively sudden and unstructured event like the gestalt switch. Scientists then often speak of the "scales falling from the eyes" or of the "lightning flash" that "inundates" a previously obscure puzzle, enabling its components to be seen in a new way that for the first time permits its solution. On other occasions the relevant information comes in sleep. No ordinary sense of the term 'interpretation' fits these flashes of intuition through which a new paradigm is born. Though such intuitions depend upon the experience, both anomalous and congruent, gained with the old paradigm, they are not logically or piecemeal linked to particular items of that experience as an interpretation would be. Instead, they gather up large portions of that experience and transform them to the rather different bundle of experience that will thereafter be linked piecemeal to the new paradigm but not to the old.”
