  I show that if a dimensionless parameter is tuned to be close to the boundary
of the positivity domain and symmetry breaking is driven by a cubic term in the
Lagrangian, the scale of the physics of symmetry breaking in a quantum field
theory as measured by the Higgs mass can be much greater than the dimensional
scales in the classical Lagrangian. Radiative corrections produce large and
physically important corrections, helping to stabilize the large VEV. The
resulting picture contrasts sharply with the "modern" view of QFT as an
effective field theory. I describe how this mechanism might produce the GUT
scale in an SU(5) model in which the dimensional parameters in the Lagrangian
are at the low scale.
