 The people of the excellent city have things in common which they all perform and comprehend, and other things which each class knows and does on its own. Each of these people reaches the state of felicity by precisely these two things …. The same is true of the actions by which felicity is attained: the more they increase and are repeated …, the stronger and more excellent and more perfect becomes the soul …, until it arrives at that stage of perfection in which it can dispense with matter so that it becomes independent of it  ….[10]  |4: 265| When one generation passes away, their bodies cease to exist and their souls are released and become happy and when other people succeed them in their ranks …, they occupy in their turn the same ranks in felicity as those who passed away before, and each joins those who resemble him in species, quantity and quality. … |5: 267| The kinds of felicity are unequal in excellence and differ in three ways, in species, quantity and quality …. (Perfect State V, 16, 2: 261–3; 4: 265; 5:  267)[11]
