I. - The Study of Scholastic Philosophy

45. In the first place, with regard to studies, We will and ordain that scholastic philosophy be made the basis of the sacred sciences. It goes without saying that if anything is met with among the scholastic doctors which may be regarded as an excess of subtlety, or which is altogether destitute of probability, We have no desire whatever to propose it for the imitation of present generations (Leo XIII. Enc. Aeterni Patris). And let it be clearly understood above all things that the scholastic philosophy We prescribe is that which the Angelic Doctor has bequeathed to us, and We, therefore, declare that all the ordinances of Our Predecessor on this subject continue fully in force, and, as far as may be necessary, We do decree anew, and confirm, and ordain that they be by all strictly observed. In seminaries where they may have been neglected let the Bishops impose them and require their observance, and let this apply also to the Superiors of religious institutions. Further let Professors remember that they cannot set St. Thomas aside, especially in metaphysical questions, without grave detriment.

46. On this philosophical foundation the theological edifice is to be solidly raised. Promote the study of theology, Venerable Brethren, by all means in your power, so that your clerics on leaving the seminaries may admire and love it, and always find their delight in it. For in the vast and varied abundance of studies opening before the mind desirous of truth, everybody knows how the old maxim describes theology as so far in front of all others that every science and art should serve it and be to it as handmaidens (Leo XIII., Lett. ap. In Magna, Dec. 10, 1889). We will add that We deem worthy of praise those who with full respect for tradition, the Holy Fathers, and the ecclesiastical magisterium, undertake, with well-balanced judgment and guided by Catholic principles (which is not always the case), seek to illustrate positive theology by throwing the light of true history upon it. Certainly more attention must be paid to positive theology than in the past, but this must be done without detriment to scholastic theology, and those are to be disapproved as of Modernist tendencies who exalt positive theology in such a way as to seem to despise the scholastic.

47. With regard to profane studies suffice it to recall here what Our Predecessor has admirably said: Apply yourselves energetically to the study of natural sciences: the brilliant discoveries and the bold and useful applications of them made in our times which have won such applause by our contemporaries will be an object of perpetual praise for those that come after us (Leo XIII. Alloc., March 7, 1880). But this do without interfering with sacred studies, as Our Predecessor in these most grave words prescribed: If you carefully search for the cause of those errors you will find that it lies in the fact that in these days when the natural sciences absorb so much study, the more severe and lofty studies have been proportionately neglected - some of them have almost passed into oblivion, some of them are pursued in a half-hearted or superficial way, and, sad to say, now that they are fallen from their old estate, they have been dis figured by perverse doctrines and monstrous errors (loco cit.). We ordain, therefore, that the study of natural science in the seminaries be carried on under this law.
