A Critique for the Methodology of Scientific Research Programmes

The purpose of the paper is to evaluate of Imre Lakatosʹ MSRP (Methodology of Scientific Research Programs). Presenting the methodology which is based on Popperian Refutationism, Lakatos intended to overcome Pluralism (, Relativism and Skepticism) and distinguishes the best theory (/program) in science. The question is that did the lakatosʹ secondary change in the form and content of MSRP -against some historical facts and criticisms- make some serious deficiencies in his methodology? The answer to this question is positive. One of Lakatosʹ changes in MSRP is to resort to a new concept of "rationality". Presenting a logical analysis, the paper shows that this change causes MSRP to be unable to distinguish the best program among others. Furthermore he gives a new definition of the term ʹmethodologyʹ. This definition, in its turn, makes MSRP main task to be inactive. Showing the irreparable harms Lakatosʹ changes produce in MSRP, the paper shows that these changes not only cannot get rid of the deficiencies therein, but it is also unable to meet lakatosʹ original purpose for MSRP.
