  The arguments surrounding the Galactic component of the cosmic rays, the
energy budget, questions of composition, spectral features, anisotropy, sources
etc, will be critically examined. We are moving into a new phase in the study
of the Galactic cosmic rays where it is becoming clear that precision
measurements are revealing new, and in some cases unexpected, features which
are forcing us to develop more sophisticated models for their production and
propagation. The fundamental concepts however appear to be quite solid and have
changed remarkably little in the more than fifty years since Ginzburg and
Syrovatskii's classic "The Origin of Cosmic Rays".
