Abstract
Basing upon Friedrich August Hayek's concept of spontaneous orders and upon the elaboration of Karl Raimund Popper's concept of open society carried out by George Soros, and also basing upon author's own former work on the explication of the concepts of self-organization and organization, it is demonstrated that this is the self-organization - a spontaneous, i.e., a natural (without the external ordering reason) formation of structures - that puts the limits to the capability of mind in changing the world. For flourishing the spontaneity, certain general rules must exist. The understanding of the self-organizing and evolving reality where we ourselves belong to is imperfect (i.e., it cannot be neutral or objective or complete) and our activity leads to the results we have not intended.
