  It is shown that Schrodinger dynamics can be embedded in a larger dynamical
theory which extends its symmetry group from the unitary group to the full
metaplectic group, i.e. the group of linear canonical transformations. Among
the newly admitted non-unitary processes are analogues of the classical
measurement process which makes it possible to treat the wave-function as an
objective property of the quantum mechanical system on the same footing as the
phase-space coordinates of a classical system. The notion of "observables" that
in general have values only when measured can then be dispensed with, and the
measurement paradox disappears.
