摘要:¿What is it that moves into researching? ¿Why do we conduct it and what is such effort worth? These are the main questions underlying this paper: a tour into several of the topics involved in the "ought to's" of social sciences -objectivity, knowledge, transformation. His claim is that "pleasure is precisely what we count on to found our commitment for researching". Such claim does not imply in any way rather soft or pleasing criteria, for only the studies of great quality, implacable rigour, conscious elaboration and sustained effort, manage to reach the place of a beautiful objects of thought, capable of modifying their authors as well as those who enter in contact with them. To replace that old barometer of objectivity by the hetherodox barometer of pleasure -the main subject of this paper- is not to lowen any of the levels that a good social practice demands. Quite the contrary.
