I think the idea of the radica1 constructivism stemmed in the l 8th century from the famous ltalian scholar vico ' s scienza nuova, who had an idea, namely, " truth is creation ", and was nurtured by kant ' s kopernikus inversion which meant subject built object and piaget ' s theory of genetic epistemology made it grow up, which was " subject and object built each other ". the idea of the radical constructivism was finally produced by v. glasersfeld ' s two essential principies. one is that knowledge is not passively obtained but actively constructed by the individual, and the other is that the function of knowledge is to accommodate and serve the organization of the empirical world, but not to discover the objective reaiity of ontology
