The social sciences approach subjective, inter-subjective, interactive, systemic, and constructed aspects of society as empirically existent systems which can be objectively proven. However, are traditionally referred to as soft sciences. This is in contrast to hard sciences, such as the natural sciences, which may focus exclusively on systemic aspects of nature.
The word "science" is older than its modern use, which is as a short-form for "natural science". Uses of the word "science", in contexts other than those of the natural sciences, are historically valid, so long as they are describing an art or organized body of knowledge which can be taught objectively. The use of the word "science" is not therefore always an attempt to claim that the subject in question ought to stand on the same footing of inquiry as a natural science.
^Weber wrote his books in German. Original titles printed after his death (1920) are most likely compilations of his unfinished works (note the 'Collected Essays...' form in titles). Many translations are made of parts or selections of various German originals, and the names of the translations often do not reveal what part of German work they contain. Weber's work is generally Iquoted according to the critical Gesamtausgabe (collected works edition), which is published by Mohr Siebeck in Tübingen, Germany.
