Abstract: In my talk I shall introduce the original concepts of P.W. Anderson about emergent behavior of many-particle (many-element) systems, as well as try to discuss qualitative vs. quantitative aspects of physical characterization of the complex systems.

On concrete examples, I shall try to enlighten what is the origin of the emergent behavior: competition of various interactions, information exchange within the elements, etc. The talk is elementary, just a view of a physicist about some philosophical aspects of our concrete concepts.
