Scientific construction and daily construction. Syntactic dimension of knowledge and the question of objectivity

In this article we insist on a commonly neglected dimension by the types implicated in everyday life, their synthetic aspect. This demands an effort to the everyday actor in order to put together the elements of his stock of knowledge in a pertinent way. This would lead in the definition of his biographical situation and the solution of concrete problems. Thus the objective of scientific constructions of reality becomes an effort to decrypt the syntactical rules used in everyday life. This, the social researcher can accomplish thanks to the common knowledge he disposes as a socialized subject, that is, as a man in society.
