Abstract

The aim of the paper is to amend the received view on the general relativity (GR) genesis and advancement by taking into account common scientific practice of its functioning, the history of science data and philosophy of science arguments. The genesis of GR as an instance of an epistemological model of mature theory change that hinges upon ‘old’ theories encounter and interaction is elucidated. I strengthen arguments in favour of the tenet that the dynamic creation of GR had been continually governed by internal tensions between two research traditions, that of special relativity and Newton’s gravity. The encounter of the traditions, their interpenetration and intertwinement entailed construction of the hybrid domain at first with an irregular set of theoretical models. Step by step, on eliminating the contradictions between the models contrived, the hybrid set was put into order. It is contended that the main reason for the GR victory over the rival programmes of Abraham and Nordström was a synthetic character of Einstein’s programme. Einstein had put forward as a basic synthetic principle the principle of equivalence that radically differed from that of rival approaches by its open, flexible and regulative character. Key words: Einstein, Abraham, Nordström, general relativity, nonmetric theories.
