  We conjecture that neutrino physics might correspond to the spontaneous
magnetisation phase of an Ising-like spin model interaction coupled to neutrino
chirality which operates at scales close to the Planck mass. We argue that this
scenario leads to a simple extension of the Standard Model with no additional
parameters that dynamically generates parity violation and spontaneous symmetry
breaking for the gauge bosons which couple to the neutrino. The neutrino mass
in the model ~ (the electroweak scale)^2 / 2M where M is the scale of the
``spin-spin'' interaction. For the ground state of the model the free energy
density corresponding to the cosmological constant is ~ the neutrino mass,
consistent with observation.
