When Thomas Kuhn talked about paradigm shifts within science, he defined a paradigm as a disciplinary matrix, which included not just the dominant theoretical framework within a given science (say, quantum mechanics in modern fundamental physics), but also the vocabulary and methods accepted within the community, the range of questions deemed interesting, as well as the textbooks and other training tools for the next generation of scientists. In a very real sense, then, physics, biology, analytical philosophy, continental philosophy, and so forth are indeed “traditions,” and the best (if not the only) way to learn them is not just by reading books at home, but by engaging in personal training over a number of years. That’s one reason why lone individuals who style themselves as revolutionary geniuses and who are convinced to have discovered proof that, for instance, general relativity is flawed are (much) more likely to be cranks than anything else. And that is also why, again in part, pseudoscience has a very different character from the genuine article.
