ABSTRACT: In order to understand the rationality of scientific creation, we must first clarify the following: (1) the historical structure of scientific creation from starting point to breakthrough, and then to establishment; (2) the process from the primary through the productive aspects of the scientific problem, the idea of creation, the primary conjecture, the scientific hypothesis, and finally the emergence of the genetic structure establishing the theory; and (3) the problem threshold of rationality in scientific creation. Given that the theory of scientific creation adopts the descriptive viewpoint of rationality, it therefore establishes rational principles such as the following: (1) a superlogical mode of thinking; (2) an analysable genetic structure which consists of the primary and productive aspects (including experiential facts, background theory, operational means, higher irrational factors, etc.); (3) a means of recourse to the effect of incubation of a higher idea; (4) a movement in thinking from generality to particularity; and (5) the replacement of irrational by rational factors.
1.The Logic Theory of Scientific Discovery and the Irrational Theory of Scientific Discovery
The modern forms of the logic theory of scientific discovery have abandoned the discovery model of pure logic, and search after the discovery logic in a broad sense. Both the retrospective inference which Hanson initiated and the inductive which Maclauin elucidated deserve serious attention among them . Their common charateristics are to resort to the irrational factors, at the same time, they are unable to expound the process of emergence of the new ideas. In addition, the rationality of discovery is summed up into "the algorithm" or "the patterns of discovery" is still put forward, and it holds that it is according to the overeconomical principle that the discovery of the scientific
