It is shown that in spite of their unconventional experimental properties the scalar mesons epsilon,delta,kappa, and S* can be understood as the unitarized remnants of conventional qq-bar states. The S* and the delta have large components of qq-barqq-bar in the form of virtual two-meson states (mainly KappaKappa-bar).
