From St. Thomas Aquinas

Each new human creature receives existence directly from Being and is therefore radically new.

Each human being is determined by antecedents as regards matter and form. But each is radically undetermined by matter and form as regards existence.

At every moment, radical newness is not only possible but actual. New persons come into existence, summoned by Being himself.

Therefore we are free not from matter and form, but within matter and form.

Newness comes from creation by Being.

The individual human creature has freedom to act as a creative mover within matter and form.

The creative mover does not destroy what came before but works within what came before. Thus the creative mover is able to act in a new way and do new things within received matter and form.

Working within all of the constraints of matter and form, genuine newness arises from the fact that each human person as a being is genuinely new. This newness is not self-generated but depends on the sustaining Creator.

Therefore new beginnings are possible in this world.

Cosmological reasoning is a facet of classical arguments for the existence of God. The thesis of Thomistic Existentialism is that Thomas Aquinas can answer many of the classic objections brought against cosmological reasoning. Topics include: the principle of sufficient reason; existence as a predicate; use of ontological reasoning; reliance on sense realism; the problem of evil; susceptibility to the critique of “ontotheology” as famously put forward by Heidegger. All of these objections receive a reply.
