عنوان مقاله [English]
Among the most fundamental and important methodological problems being in close relation with epistemology consists in the problem that what the part of paradigms, namely principles, in knowledge and attaining reality is. May one paradigm be regarded as superior to some other paradigm(s) to be preferred? In the paper, therefore, with an emphasis on irrationality of the teaching of framework, the distinction between mental frame and principles as well as their qualities have been studied. Again, possibility for agreeing with paradigms meant by the meaning of principles has been surveyed; in addition, the part of such a meaning of paradigm in appearance of knowledge and attaining reality has been made clear. Finally, all types of paradigm has been studied. As concluded in the study, from each principle, some view appropriate to itself would appear. Principles, particularly those of epistemology, are of considerable part in theories. Would such a multiplicity lead to a kind of skepticism in methodology of sciences? If any, what method may be preferred? The study has ended with an attempt to find a solution for the question.
