  I present a grand view of some of the main particle physics challenges from a
neutrino perspective. After a brief review of the current status of neutrino
physics, I illustrate the possible role neutrinos can play in the elucidation
of various puzzles in particle physics and cosmology, for which the Standard
Model offers no answer.
