Abstract
The concept of Spontaneous Symmetry Breaking (SSB) represents a real breakthrough for the present description of fundamental interactions by means of gauge theories. Although the underlying ideas were ancient, their formalization required a long time, due to epistemological obstacles and technical difficulties. In this paper, the main steps of SSB evolution are briefly outlined, from the introduction of the order parameter in the Thirties to the birth of the many-body theory at the end of the Fifties. In this context, the contribute of the capital L. Landau’s works on phase transitions and quantum fluids, as well as of the seminal ideas of F. London, is highlighted, and the phenomenological approach in theoretical physics (whose features are schematically underlined) is showed to be crucial in the rising field of complex systems.
