All things are in the intended endpoint, and this mode of being is called will or desire.
Since beings desire to exist, because to exist is a good thing: they desire the One without which they cannot exist.
The fact is that man has no longing for any other nature but desires only to be perfect in his own.
We see that God has implanted in all things a natural desire to exist with the fullest measure of existence that is compatible with their particular nature. To this end they are endowed with suitable faculties and activities; and by means of these there is in them a discernment that is natural and in keeping with the purpose of their knowledge, which ensures their natural inclination serving its purpose and being able to reach its fulfilment in that object towards which it is attracted by the weight of its own nature.
The intellect alone has an eye for viewing an essence, which it cannot see except in the true Cause, which is the Fount of all desire. Moreover, since all things seek to exist, then in all things there is desire from the Fount-of-desire, wherein being and desire coincide in the Same.
