  We propose a new method for the study of the chiral properties of the ground
state in Quantum Field Theories (QFT's) which is based on the computation of
the probability distribution function (p.d.f.) of the chiral condensate in the
chiral limit. We show how despite of the fact that Grassmann variables cannot
be simulated on a computer, an analysis of spontaneous symmetry breaking
without a symmetry breaking external field, which is standard in the case of
spin systems, can also be done in QFT's with fermion degrees of freedom.
