  Recent advances in estimating black hole masses for AGN show that radio
luminosity is dependent on black hole mass and accretion rate. In this paper we
outline a possible scheme for unifying radio-quiet and radio-loud AGN. We take
the ``optimistic'' view that the mass and spin of the central black hole, the
accretion rate onto it, plus orientation and a weak environmental dependence,
fully determine the observed properties of AGN.
