Idea of Reality and Epistemological Constructivism.
Genesis and evolution of the idea of reality in modern philosophy, and mechanisms of constructing reality in Philosophy and Science are examined in this article. The problem of constructing reality is analyzed in context of the polemics between realism and antirealism, and different versions of epistemological constructivism. The position according to which the transfer from the ontology of things to the ontology of reality is the organic element of mathematical natural knowledge forming is argued.
