 (b) After passing from one thought style to another within “the same” scientific discipline, research problems change. Losses appear along with benefits. For example, when the contemporary concept of syphilis was created one learned very much, but many details of earlier theories were also lost. Earlier researchers did not know many of the details that we know, but knew more about what according to them had a greater value. Later researchers see many problems which their predecessors treated as unimportant or senseless. “This creates specialized valuation and characteristic intolerance, which are features shared by all exclusive communities” (1935a, IV.3). This valuation becomes stronger, for after passing from one thought style to another the research methods and standards for evaluating research results change to a greater or lesser extent.
