I like Auriol's dismissal of the theory that the generation of substantial forms requires the intervention of higher powers:
‘Hoc est refugium miserorum in philosophia, sicut Deus est refugium miserorum in theologia.’ (S IV.1.1.iii)
‘This is the refuge of the wretched in philosophy, just as God is the refuge of the wretched in theology.’
(Anneliese Maier, Zwei Grundprobleme, 3e (1968), p. 182 n. 29.)
