Science Model of Lakatos

This study aims to determine the outlines of the science model of Imre Lakatos. To this end, firstly, Lakatos’s view on the development of falsificationism is discussed. Against to dogmatic and naive methodological forms, Lakatos proposes a sophisticated form of falsificationism. It is showed that the key development in moving from naive to sophisticated methodological falsificationism is to take the unit of assessment in science not as an individual theory standing in relation to evidence, but as a series of theories grouped within what Lakatos calls a research programme. Finally, it is debated that, the history of science is, according to Lakatos, a history of the development of theories within a larger structure of competing research programmes.Keywords: Demarcation problem, sophisticated falsificationism, the methodology of scientific research programmes, scientific progress.
