There is no reason why an extraphysical general principle is necessarily to be avoided, since such principles could conceivably serve as useful working hypotheses. For the history of scientific research is full of examples in which it was very fruitful indeed to assume that certain objects or elements might be real, long before any procedures were known which would permit them to be observed directly.

We were created for eternal life by our Creator, we are called to it by the word of God, and we are renewed by holy Baptism. And Christ the Son of God came into the world for this, that He should call us and take us there, and He is the one thing needful. For this reason your very first endeavor and care should be to receive it. Without it everything is as nothing, though you have the whole world under you.
Tikhon of Zadonsk
Do you desire security? Here you have it. The Lord says to you, "I will never abandon you, I will always be with you." If a good man made you such a promise, you would trust him. God makes it, and do you doubt? Do you seek a support more sure than the word of God, which is infallible? Surely, He has made the promise, He has written it, He has pledged His word for it, it is most certain.
Augustine of Hippo
We may... have surmised nebulae to be no other than clusters of stars disguised by their very great distance, but a longer experience and better acquaintance with the nature of nebulae, will not allow a general admission of such a principle, although undoubtedly a cluster of stars may assume a nebulous appearance when it is too remote for us to discern the stars of which it is composed.
William Herschel
There is a philosophy that says that if something is unobservable -- unobservable in principle -- it is not part of science. If there is no way to falsify or confirm a hypothesis, it belongs to the realm of metaphysical speculation, together with astrology and spiritualism. By that standard, most of the universe has no scientific reality -- it's just a figment of our imaginations.
Leonard Susskind
Every philosophy is complete in itself and, like a genuine work of art, contains the totality. Just as the works of Apelles and Sophocles, if Raphael and Shakespeare had known them, should not have appeared to them as mere preliminary exercises for their own work, but rather as a kindred force of the spirit, so, too reason cannot find in its own earlier forms mere useful preliminary exercises for itself.
Georg Wilhelm Friedrich Hegel
