The paper addresses following questions: Is the ethos, described by Merton, still valid for science that met serious changes in its economic, social, and cultural environment? Can ethos - narrowly understood as a set of values - be effective guide for behaviour that would be functional methodologically and institutionally for science? And, first of all, does the general notion of 'science', including all forms of intellectual, conceptual, and explanatory activities, conducted in existing scientific institutions, apply to something anymore? Positive answer for these questions demands some differentiations, especially exclusion of the so-called 'industrial science' from regulation by the concept of ethos.
