Therefore, in denying the existence of a providence, they plainly denied the existence of God, who is the fountain and source of all things. It followed that they should either affirm that those things which exist have always existed, or were produced of their own accord, or arose from a meeting together of minute seeds.
It cannot be said that that which exists, and is visible, always existed; for it cannot exist of itself without some beginning. But nothing can be produced of its own accord, because there is no nature without one who generates it. But how could there be original  seeds, since both the seeds arise from objects,  and, in their turn, objects from seeds? Therefore there is no seed which has not origin. Thus it came to pass, that when they supposed that the world was produced by no providence, they did not suppose that even man was produced by any plan.  But if no plan was made use of in the creation of man, therefore the soul cannot be immortal. But others, on the other hand, thought there was but one God, and that the world was made by Him, and made for the sake of men, and that souls are immortal. But though they entertained true sentiments, nevertheless they did not perceive the causes, or reasons, or issues of this divine work and design, so as to complete the whole mystery of the truth, and to comprise it within some limit. But that which they were not able to do, because they did not hold the truth in its integrity,  must be done by us, who know it on the announcement of God.
 Summam. Lactantius uses this word to express a compendious summary of divine mysteries.  Semina principalia.  Ex rebus.  Aliquâ ratione.  Perpetuo, i.e., without intermission.
