The subject considered in the article is dependence of political processes on the structure of informational space. The author holds that two processes are simultaneously developing in the world: on the one hand, the spread of democracy implies necessity of policy legitimization, which increases the necessity of mass consciousness regulation; on the other hand, with development of civil society based on pluralism, it is growing an ever more complicated thing to retain monopoly of consciousness manipulation, and therefore it's growing an ever more complicated thing to regulate public opinion. Impact of new informational technologies on civil society and on the structure of scientific knowledge is also analyzed in the article.
