• The pion-nucleon scattering is treated in the Tamm-Dancoff approximation using the symmetrical ps-ps theory, with emphasis particularly on the renormalization procedure. The number of mesons and nucleon-pairs is restricted up to two and one, respectively, in every intermediate state. In order to perform the renormalization consistently, it is required to adopt the five-box approximation of Bethe and Dyson. But even in this case, the meson self-energy term is not treated consistently and should be discarded. A method is proposed to remove the overlapping divergences and it is shown that the Salam's procedure can be carried out in a closed form. The scattering phase shifts are evaluated and compared with experiments.
