O OBSTÁCULOS EPISTEMOLÓGICOS DE BACHELARD E O ENSINO DE CIÊNCIAS

Abstract

The present paper adresses itself to the epistemiological obstacles proposed by Gaston Bachelard in his historical epistemiology. According to Bachelard, since the act of knowing is always opposed to previously accepted knowledge, all new concepts in fact derive from the evolution of a thought process. In this view an error is seen to have a positive connotation, thus any sort of progress within a philosophy of science is achieved through increasing rationalism and at the expense of the original realism.Since Bachelard postulates a break between common sense and scientific knowledge, his entire output exhibits such a pattern of discontinuity. Based upon Bachelard's insistence upon a thorough reorganization of thought, some of the implications of his ideas for science teaching are also debated.
