This program is based on effective Lagrangian techniques and is an expansion in the powers of the momenta and the powers of the quark masses, which correct the soft-pion theorems. After briefly reviewing these features and some results, we address the implications of this program to $\pi-N$ scattering, the $\pi-N$ sigma term and some recent investigations of the implications of chiral symmetry to nucleon-nucleon forces. We finally look at the implications of chiral perturbation theory to hadron mass relations. Educational Use Research Learning Resource Type Article Page Count 20
