As it happens I've recently started Blessed John Henry Newman's
Idea of a University for my personal reading, both to celebrate his recent beatification and to consider such a brilliant, Catholic mind's meditations on the subject of university education, theology, and the relation between the two (the subject being peculiarly pertinent to me, obviously). So imagine my delight at discovering this passage not forty pages into the work:
"I cannot so construct my definition of the subject-matter of University Knowledge, and so draw my boundary lines around it, as to include therein the other sciences commonly studied at Universities, and to exclude the science of Religion. For instance, are we to limit our idea of University Knowledge by the evidence of our senses? then we exclude ethics; by intuition? we exclude history; by testimony? we exclude metaphysics; by abstract reasoning? we exclude physics. Is not the being of a God reported to us by testimony, handed down by history, inferred by an inductive process, brought home to us by metaphysical necessity, urged on us by the suggestions of our conscience? It is a truth in the natural order, as well as in the supernatural. So much for its origin; and, when obtained, what is it worth? Is it a great truth or a small one? Is it a comprehensive truth? Say that no other religious idea whatever were given but it, and you have enough to fill the mind; you have at once a whole dogmatic system. The word "God" is a Theology in itself, indivisibly one, inexhaustibly various, from the vastness and the simplicity of its meaning. Admit a God, and you introduce among the subjects of your knowledge, a fact encompassing, closing in upon, absorbing, every other fact conceivable. How can we investigate any part of any order of Knowledge, and stop short of that which enters into every order? All true principles run over with it, all phenomena converge to it; it is truly the First and the Last. In word indeed, and in idea, it is easy enough to divide Knowledge into human and divine, secular and religious, and to lay down that we will address ourselves to the one without interfering with the other; but it is impossible in fact. Granting that divine truth differs in kind from human, so do human truths differ in kind one from another. If the knowledge of the Creator is in a different order from knowledge of the creature, so, in like manner, metaphysical science is in a different order from physical, physics from history, history from ethics. You will soon break up into fragments the whole circle of secular knowledge, if you begin the mutilation with divine."
