Abstract :
We revise the role played by symmetry in the study of the low-lying baryon spectrum and comment on the difficulties when trying to generalize the symmetry pattern to higher energy states. We show that for the (N, Δ) part such a generalization is plausible allowing the identification of spectral regularities and the prediction of until now non-identified resonances.
