A simple calculation in the framework of the chiral quark theory of Manohar and Georgi yields results that can account for many of the ``failures`` of the naive quark model: significant strange quark content in the nucleon as indicated by the value of {sigma}{sub {pi}{ital N}}, the {ital d}{ovr bar} a symmetry in the nucleon as measured by the deviation from the Gottfried sum rule and by the Drell-Yan process, as well as the various quark contributions to the nucleon spin as measured by deep inelastic polarized lepton-nucleon scattering.
