On the other hand...
On the other hand, in creative acts in which there is no motion, the concept of final cause and effect can be correctly applied although there is no place here for ghāyah to have the sense of a terminus of motion. However, sometimes it is used in the sense of the final cause, and here one must take care not to confuse these two senses, and not to relate the characteristics of one to the other.
The relation between agent, action and result has been the topic of numerous philosophical discussions, some of which are presented in Lesson Thirty-Nine. Now we shall begin to explain some issues pertaining to the present discussion and which are useful for explaining the correct meaning of the divine purpose of creation.
Some Points Usually, the voluntary actions of human beings are performed in this way: first, there appears the idea of the action and its result, an assent of the priority of the act for obtaining the result and the benefit accruing therefrom, followed by a yearning in the soul for the good, perfection and benefit resulting from that act.
When requisite conditions obtain and obstacles are removed, one decides to perform the action, and, in fact, the main factor and stimulus for the performance of an action is the yearning for its benefits. Therefore, the final cause must be considered to be this yearning. That to which the yearning is directed is figuratively and accidentally called the final cause.
It must not be imagined that this process is necessary in all voluntary actions nor that if an agent lacks acquired knowledge and a yearning of the soul, his action will not be voluntary or lack a final cause. Rather, what is necessary in any voluntary action is knowledge and yearning in general, regardless of whether the knowledge is by presence or acquired, and whether the yearning is added to the essence or is the essence itself.
Therefore, the final cause of complete immaterial things is the same as the love of their own essences, which is subordinately directed to their effects as well, a love which is identical to the essence of its agent. Therefore, for such cases, the efficient cause and the final cause is the essence of the agent. As was indicated, an action is desired subordinate to the desire of the goodness and perfection that result from it.
Therefore, the desirability of the purpose is prior to the desirability of the act, and the desirability of the act is subordinate and respectival.
