Emergence, by providing a new suggestive key of reading of collective phenomena which are observed in several systems, can be considered one of the most important concepts of contemporary science. In nature there are various emergent states, such as superconductors, that are characterized by a new type of order, of properties which allow us to analyse the organization processes of their elementary constituents. In the light of the phenomenon of superconductivity one can claim that quantum field theory, the fundamental mathematical structure able to provide the syntax of contemporary theoretical physics, has not an ontological primary reality but works well just because of the emergent universality of superconductivity, because of the existence of phenomena of collective organization inside physical systems.

Keywords: Emergence, collective behaviour, superconductivity, spontaneous symmetry breaking, quantum field theory, coherence
