normal science

is, by no means, science guided by a coherent system of rules. On the contrary, a paradigm can guide the investigation also in the absence of rules.

Thus the question is for Kuhn to investigate by means of the paradigm what makes possible the constitution of what he calls a 'normal science'. That is to say, the science which can decide if a certain problem will be considered scientific or not. Normal science does not mean at all a science guided by a coherent system of rules, on the contrary, the rules can be derived from the paradigms, but the paradigms can guide the investigation also in the absence of rules. This is precisely the second meaning of the term 'paradigm', which Kuhn considered the most new and profound, though it is in truth the oldest. The paradigm is in this sense just an example, a single phenomenon, a singularity, which can be repeated and thus acquires the capability of tacitly modeling the behavior and the practice of scientist' (Agamben 'What is a paradigm' NET).
