The fact that the macroscopic phenomenon of light, can be stated as a set of wave-functions, whose polarization can be stated as vector-sums, in which either component can additionally be phase-shifted with respect to the other, is also the direct statement today, of what the possible states of a photon are, entirely justified by the concept of superposition of states.

The problem with this approach is, that it’s possible for the macroscopic inspection of a phenomenon to reveal properties, which individual particles – i.e. photons – *do not* have.

What the real set of properties, of one photon, are, remains to be discovered at some future point in time.
