General Cosmology

...concerning composite [beings] in general are demonstrated in First Philosophy original: "philosophia prima" – A term for Metaphysics or Ontology, the study of the most basic principles of existence. (§ 2). From that same source, it is therefore understood what kind of being every world is, and consequently even this one, which exists and is subject to our contemplation. Now, since nothing is without a sufficient reason original: "ratione sufficiente" – The Principle of Sufficient Reason is a core rule in Wolff’s philosophy, stating that everything must have an explanation for why it exists or why it is the way it is. why it should be rather than not be (§ 70, Ontology), a reason must also necessarily be given why this world exists, and why it appears in this specific way rather than another. Therefore, it is established that we must admit a being of such a kind in which is contained the sufficient reason for the existence of such a universe—the kind of universe that it is demonstrated every universe must be—and consequently, this universe which exists cannot not exist; a being to whom such predicates attributes or qualities asserted about a subject belong, through which it is understood both why the world exists and why it exists in this way (§ 56, Ontology). And so, from the principles of Cosmology, we gather not only the existence of the Author of the universe The "Author of the universe" refers to God as the rational designer., but also what kind of being that Author of the universe is, and consequently what His attributes are (§ 457, Ontology).

This same point is also shown as follows. Since in general Cosmology those things demonstrated in Ontology concerning being in general and every composite being are applied to the world or universe (§ 2), from that same source it is understood what kind of being every world is, and consequently this one which exists. In this way, it simultaneously becomes apparent what kind of sufficient reason must be presupposed, both for existence in its simplest sense and especially for the existence of such a universe as every universe is found to be (§ 70, 118, Ontology). But while we do not find that reason within the world itself, but understand that it must be sought outside it in another being, the dependence of the world upon a cause distinct from itself becomes evident (§ 851, 881, Ontology); and simultaneously, the manner of this dependence is made manifest from the sufficient reason, insofar as through it we understand (§ 56, Ontology) what that cause must be like so that the world can depend upon it. In this way, therefore, from the principles of Cosmology, it is gathered not only that an Author of the universe exists, but also what He is like, and consequently what His attributes are (§ 457, Ontology).
