Context

“He intends only to communicate His perfection, which is His goodness; while every creature intends to acquire its own perfection, which is the likeness of the divine perfection and goodness. Therefore the divine goodness is the end of all things. Reply Obj. 1: To act from need belongs only to an imperfect agent, which by its nature is both agent and patient. But this does not belong to God, and therefore He alone is the most perfectly liberal giver, because He does not act for His own profit, but only for His own goodness. Reply Obj. 2: The form of the thing generated is not the end of generation, except inasmuch as it is the likeness of the form of the generator, which intends to communicate its own likeness;” source
