We thus see that the various actions performed are governed by what is intended through them. Yet what is intended through them is what comes after them: the final goal is the finished work that will come at the end of everything. If so, someone who wants to understand the purpose of the earlier actions must first understand the general direction until the end. Then afterwards he can go back to investigate the details. This way he will not have to remain in suspense until the end while seeking to understand the details of the early stages. When he already has a grasp of the overall direction, he will be able to understand each successive detail in its place.
