This paper discussed the ”Leisure Studies” from the perspective of Philosophy of Science and Sociology of Knowledge. Leisure is a paradoxical process of ”individual. freedom/ structure. constraint”. On the level of world view, there are Interpretative, Positivist and Conflict paradigms. However, on the methodological level, there are qualitative and quantitative approaches. We are expecting the emergence of multiparadigms of Leisure Studies in the near future.
