I found an interesting passage by St. Gregory Nazianzen, in his funeral oration for St. Basil the Great, which discusses whether or not Christians learn about the natural sciences and other secular topics.
I take it as admitted by men of sense, that the first of our advantages is education; and not only this our more noble form of it, which disregards rhetorical ornaments and glory, and holds to salvation, and beauty in the objects of our contemplation: but even that external culture which many Christians ill-judgingly abhor, as treacherous and dangerous, and keeping us afar from God. For as we ought not to neglect the heavens, and earth, and air, and all such things, because some have wrongly seized upon them, and honour God’s works instead of God: but to reap what advantage we can from them for our life and enjoyment, while we avoid their dangers; not raising creation, as foolish men do, in revolt against the Creator, but from the works of nature apprehending the Worker, and, as the divine apostle says, bringing into captivity every thought to Christ: and again, as we know that neither fire, nor food, nor iron, nor any other of the elements, is of itself most useful, or most harmful, except according to the will of those who use it; and as we have compounded healthful drugs from certain of the reptiles; so from secular literature we have received principles of enquiry and speculation, while we have rejected their idolatry, terror, and pit of destruction. Nay, even these have aided us in our religion, by our perception of the contrast between what is worse and what is better, and by gaining strength for our doctrine from the weakness of theirs. We must not then dishonour education, because some men are pleased to do so, but rather suppose such men to be boorish and uneducated, desiring all men to be as they themselves are, in order to hide themselves in the general, and escape the detection of their want of culture.
St. Gregory Nazianzen. Oration XLIII, §11. (NPNF2 7:398-399).
