  In this paper we will attempt to show that the Dirac theory lends itself to
an interpretation in terms of a unified sub-quantum mechanical field theory
where, the fundamental force fields are weak electric and weak magnetic fields.
We present an electron model based on some of the predictions of the Dirac
theory and justify our arguments by showing that the model not only yields the
correct value for the g-factor but also gives us the very small correction to
the magnetic moment as obtained in the renormalization programme of quantum
electrodynamics. The model also allows us to give a new meaning to the negative
energy state of an electron. The general outlines of the unified field theory
are given and the connection between fluctuations at the Planck and Compton
scales is presented in terms of concrete physical events.
