The strong evidence for the `triviality' of (lambda Phi^4)_4 theory is notincompatible with spontaneous symmetry breaking. Indeed, for a `trivial' theorythe effective potential should be given exactly by the classical potential plusthe free-field zero-point energy of the shifted field; i.e., by the one-loopeffective potential. When this is renormalized in a simple, but nonperturbativeway, one finds, self-consistently, that the shifted field does becomenon-interacting in the continuum limit. For a classically scale-invariant (CSI)lambda Phi^4 theory one finds m_h^2 = 8 pi^2 v^2, predicting a 2.2 TeV Higgsboson. Here we extend our earlier work in three ways: (i) we discuss theanalogy with the hard-sphere Bose gas; (ii) we extend the analysis from the CSIcase to the general case; and (iii) we propose a test of the predicted shape ofthe effective potential that could be tested in a lattice simulation.Comment: 22 pages, LaTeX, DE-FG05-92ER40717-
