  In this talk the role of spin and polarization is discussed in experimental
search for new excited baryon states and in the study of the internal
quark-gluon structure of the proton and neutron. Also the perspective of spin
physics at the 12 GeV CEBAF electron accelerator is discussed and what we hope
to learn about fundamental properties of hadrons such as their
multi-dimensional structure through the momentum and spatial imaging, and about
the forces on the quarks in the proton and how quark confinement may be
realized through the spatial distribution of such forces.
