Also of importance in this area is Kuhn's [0] the "Structure of Scientific Revolutions" [1], which not only first coined the term "paradigm shift", but is also probably the best account of how science really works.
Your comment does not make any sense to me. 'The Structure of Scientific Revolutions' does not just propose 'theories': it mainly shows how the Popperian and other accounts of 'how science works' are simply wrong, as a close consideration of historical evidence shows that science just does not work that way. It goes on to explain why it would also be impractical if science did work that way. Those parts are all pretty uncontroversial.
The account of how science does work is still being debated. Perhaps Kuhn disavowed his account later, but that doesn't matter with respect to the most important parts of the book.
