  Observations in the far-infrared are the best way to make an unbiased survey
of active galaxies in the loosest sense - but separating the true quasars from
the starburst may be difficult. There is in fact much evidence to suggest that
starburst and AGN activity are intimately connected, and FIRST will help us to
explore this link. Since the last major FIRST conference in Grenoble, this
issue has become even more central to modern astrophysics, with the realisation
of the dominance of the FIR background, the discovery of high redshift SCUBA
sources, and the emergence of the black hole mass deficit problem. What
dominates the cosmic energy budget - nuclear fusion or accretion ?
