I wish you could go into more detail if you have time today. Does Aquinas believe you can PROVE from reason that creation came from nothing?
Go back and read posts # 1 & 5. Here is the pertinent link:
On the contrary it is said (Rom. xi, 36): From him and by him and in him are all things.
I answer that the ancients in their investigations of nature proceeded in accordance with the order of human knowledge. Wherefore as human knowledge reaches the intellect by beginning with the senses, the early philosophers were intent on the domain of the senses, and thence by degrees reached the realm of the intellect. And seeing that accidental forms are in themselves objects of sense, whereas substantial forms are not, the early philosophers said that all forms are accidental, and that matter alone is a substance. And because substance suffices to cause accidents that result from the substantial elements, the early philosophers held that there is no other cause besides matter, and that matter is the cause of whatever we observe in the sensible world: and consequently they were forced to state that matter itself has no cause, and to deny absolutely the existence of an efficient cause. The later philosophers, however, began to take some notice of substantial forms: yet they did not attain to the knowledge of universals, and they were wholly intent on the observation of special forms; and so they posited indeed certain active causes, not such as give being to things in their universality, but which transmute matter to this or that form: these causes they called intelligence, attraction and repulsion, which they held responsible for adhesion and separation. Wherefore according to them qot all beings came from an efficient cause, and matter was in existence before any efficient cause came into action. Subsequent to these the philosophers as Plato, Aristotle and their disciples, attained to the study of universal being: and hence they alone posited a universal cause of things, from which all others came into being, as Augustine states (De Civ. Dei viii, 4). This is in agreement with the Catholic Faith; and may be proved by the three arguments that follow.
First, if in a number of things we find something that is common to all, we must conclude that this something was the effect of some one cause: for it is not possible that to each one by reason of itself this common something belong, since each one by itself is different from the others: and diversity of causes produces a diversity of effects. Seeing then that being is found to be common to all things, which are by themselves distinct from one another, it follows of necessity that they must come into being not by themselves, but by the action of some cause. Seemingly this is Plato’s argument, since he required every multitude to be preceded by unity not only as regards number but also in reality. The second argument is that whenever something is found to be in several things by participation in various degrees, it must be derived by those in which it exists imperfectly from that one in which it exists most perfectly: because where there are positive degrees of a thing so that we ascribe it to this one more and to that one less, this is in reference to one thing to which they approach, one nearer than another: for if each one were of itself competent to have it, there would be no reason why one should have it more than another. Thus fire, which is the extreme of heat, is the cause of heat in all things hot. Now there is one being most perfect and most true: which follows from the fact that there is a mover altogether immovable and absolutely perfect, as philosophers have proved. Consequently all other less perfect beings must needs derive being therefrom. This is the argument of the Philosopher (Metaph. ii, I).
The third argument is based on the principle that whatsoever is through another is to be reduced to that which is of itself. Wherefore if there were a per se heat, it would be the cause of all hot things, that have heat by way of participation. Now there is a being that is its own being: and this follows from the fact that there must needs be a being that is pure act and wherein there is no composition. Hence from that one being all other beings that are not their own being, but have being by participation, must needs proceed. This is the argument of Avicenna (in Metaph. viii, 6; ix, 8). Thus reason proves and faith holds that all things are created by God,
