The article focuses on the phenomenon of daily reality as an element of public life. The author analyses the principles this notion is based on. Daily reality is a mode that states the authenticity of a man’s being. The premises which have led to the necessity of the notion’s study are defined, the latter being a fundamental rethinking of rationality’s role as a method to figure out where a man’s place in the world is. The author analyses methodology of the problem within the philosophical discourse, and gives a socio-cultural justification of daily reality structures and levels.
