Augustine has an interesting comment on this:
With the mind and intellect which you have given them, they investigate these matters. They have found out much. (…) People who have no understanding of these things are amazed and stupefied. Those who know are exultant and are admired. Their irreligious pride makes them withdraw from you and eclipse your great light from reaching themselves. They can foresee a future eclipse of the sun but do not perceive their own eclipse in the present. For they do not in a religious spirit investigate the source of the intelligence with which they research into these matters. Moreover, when they do discover that you are their Maker, they do not give themselves to you so that you may preserve what you have made. (V.4)
Augustine, an intelligent and educated man, does not need to forsake scientific explanations of the natural universe to glorify his God. He suggests instead that things of nature can be scientifically explained by man because God had given man the ability to observe, research, and theorize.
In the time of Augustine, belief based on faith was given more import than what might contradict that by scientific thought and findings. Augustine is seeking a way to accept both.
