Hi, I understand from a little reading I’ve been doing that modern scientists assume only two of Aristotles’ four causes; that is, the two having to do with the empirical world, efficient causes and empirical causes. They reject formal and final causality. Is there a proof for formal and final causality? I realize I am asking a somewhat technical question, but perhaps there is a scholar out there who can answer it. Thank you.

Welcome to CAF Birdchest:
I’ll give it a go, with your permission. But, beware, just about as soon as the rhetoric begins, you’ll be swamped with naysayers, those opposed to God and His existence. A few are here for erudition. Most of the rest are here to annoy. So, if you can get past the curmudgeons, let’s get started.
There are four causes of being. But, before we can know them, we must know on what they depend for their existence.
To begin, it is important to understand what a cause is, in the manner meant by a general science of nature and Aristotle and Aquinas.
A cause is that on which a thing (the effect) depends in being or becoming. As such, a cause is a principle but not a first principle.
A principle is that from which anything flows in any manner whatsoever. While causes can be principles, principles are not necessarily causes.
A cause is that upon which the effect depends either for its being or for its coming to be. A principle is different from a cause in two ways: first, because it is the ultimate source for everything in the order under consideration. And, second, because it is itself underived or presuppositionless.
From an analysis of nature and science we see that things are caused. From an analysis of the action of causation, we discover that there are three principles that are the ground of being in the order of causation. These three principles are
primary matter, (first)
privation and (first)
possession. These are the contraries that stand out when we investigate change and motion. I have indicated that each of these three principles are firsts in their orders of being and are presupposed by nothing.
For the sake of simplicity, an example could be taken from ordinary coming-to-be, although this description does not describe first principles
per se. The physical manifestation of primary matter would be the human male and female gametes. At the first moment of change (into the zygote) the
primary matter would perhaps be the combined “stuff” of the two gametes, including the separate DNA’s.
Privation would be the absence of fusion of the DNA strands prior to fusion, or the privation of the instantiated human being. And,
possession would be the fused DNA and the instantiated human life, in a single cell surrounded by the rest of the universe.
Now, that’s hardly a sufficient metaphysical account. But, it is an account that will work, in the absence of anything that will allow us to look metaphysically closer at the process. One day, we may look deep enough to understand how the foregoing mechanism actually becomes manifested as a living thing. But for now, at least we know something about the process.
The four causes of
being are:
(1) From Primary or secondary matter, the material cause or causes - that matter having the privation of the final form.
(2) From the need for something external get the matter and form together, so to speak, the primary or secondary efficient causes.
(3) From the final form that the effect will own upon fusion of the matter with the appropriate form, the formal cause, or causes.
(4) From the purpose for which the fusion is being made to take place, the final cause, or causes.
