In what follows confinement will be taken to mean the following: in a state which contains an isolated (massless) q~ pair on top of the free Dirac vacuum there exists a long range strong attractive force which forbids states in which the q and ~ are arbitrarily far apart. The only properties of the force which we need are: Work supported in part by the Israel Commission for Basic Research and US-Israel Bi-National Science Foundation (BSF).

N2 - We exhibit a mechanism which breaks chiral symmetry in a confining theory. The ingredients are the postulated existence of chirally invariant confining forces and the Pauli principle. The qualitative structure of the fermion vacuum is outlined and the chiral parameters (〈ψψ〉, m constituent) are related to the strength of the confining force (essentially the Regge slope). The suggested mechanism is anlogous to the BCS phenomenon and the counterpart of the Cooper instability is proved.
