Abstract

Actuality of the article’s topic based on post-non-classical processes of the becoming of contemporary scientific knowledge – stochastics, singularity, innovative, interdisciplinarity etc. The article’s aim is clarification of conceptual, historical-philosophical, methodological points of crossing of social philosophy and social psychology as two spheres of social-humanitarian knowledge. Conclusions. Showed, these two spheres are complexity researching systems, combined different – philosophical and psychological, axiological and ontological, gnoseological and world-outlook questions from the conceptual point of view. Understood, social psychology is directed on researching of two different classes – individual and overindividual phenomenon and social philosophy is directed on universal foundations of civilization existence and development of a society as a whole system through the human being and values of humanitarian priorities. In this contest, founded, social philosophy can make functions of metatheory in boundaries of a determined variant of social psychology, because of social philosophy can carry on reflective function regarding world-outlook foundations of social-psychological knowledge. Researched, from the historical-philosophical point of view on the non-classical period (from the second half of the 19th) we can observe difference of social-philosophical and social-psychological knowledge and on the post-non-classical period (from the second half of the 20th) we can see manifestations of conditions for the interdisciplinary dialogue. Understood, from the methodological point of view social philosophy and social psychology have the same ontological optics: contemporary world is open, plural, incomplete (famous K. Gödel’s principle), relative. That’s why from classical methods, based on fundamentalism and normativeness, these spheres are directed on researching of singular phenomenon, open systems, which have elements of uncertainty.
