Principiate

Of Subſtances ſome are Principles, ſome Principiates. By Principles, I mean ſubſtances that are cauſes of other things, but are themſelves uncauſed. By Principiates (give me leave to make an Engliſh word of one not very good Latin) I mean ſubſtances that are cauſed, or compoſed of Principles. Principles make, Principiates are made to be.

From what hath been ſaid above, it is evident, why all Things of the Body are Principiates, that is, Contextures conſiſting of Fibres from their Principles, which are Receptacles of Love and Wiſdom, and that ſuch as the Principles are, ſuch muſt alſo the Principiates be, wherefore whitherſoever the Principles tend, the Principiates follow, they cannot be ſeparated.

The Latin actualitas comes from actus, which in turn comes from agens and agere; so that, in calling a being actual, we name it in virtue of its active principle, its agency. That is why the actual principle of a being is potior, since it is more powerful than anything else that belongs to the ontological make-up of the being. In a word, then, the term actual designates a principle not a principiate, a source not a result.

Both the Kingly and Prophetical Offices of Jesus Christ are principiated in this

In short, the principles of any science are not proved by the science employing them. Principles are only inadequately and virtually the wholes which they principiate; otherwise, in knowing the principles, the mind would also actually know what is principiated.

According to Scotus, then, self-change is possible when one and the same thing has a form φ that grounds the active causal potency to cause equivocally another form ψ and is also in passive potency to receive φ. In the language of principles, one and the same thing has an active principle to produce a form it currently lacks and a passive principle of receiving such a form, and these two principles jointly bring about (or “principiate”) the result (In Metaph. 9, q. 14, nn. 84–5).

For, while we are, certainly, we cannot imagine Two diſtinct Durations; but one, which in reſpct^([sic]) to our Nature, that is principiate, mutable, and terminable, doth contain deſignable Terms; […]

[W]e are at a loſs for a ſcientificall account even of our Senſes, the moſt knowable of our facultyes. Our eyes, that ſee other things, ſee not themſelves: And thoſe principiate foundations of knowledge are themſelvs unknown.
