according as the intellectual nature dominated over the emotional, or the emotions quelled the conscious exercise of reason, yet reached out and upward from what knowledge and reason had given as a base to spring from. Thus the mediaeval spirit, variant within its lines of likeness; and of a piece with it was the field it worked in, which made its range and scope. Here as well, a saving knowledge of God and the soul was central and chief among all intellectual interests. None denied this. Augustine, the universal prototype of the mediaeval mind, had cried, “God and the soul, these will I know, and these are all.” But wide had been the scope of _his_ knowledge of God and the soul; and in the centuries which hung upon his words, wide also was the range of knowledge subsumed under those capitals. How would one know God and the soul? Might one not know God in all His universe, in the height and breadth thereof, and backwards and forwards through the reach of time? Might not one also know the soul in all its operations, all its queries and desires; would not it and they, and their activities, make up the complementary side of knowledge--complementary to the primal object, God, known in His eternity, in His temporal creation, in His everlasting governance? Wide or narrow might be the intellectual interests included within a knowledge of God and the soul. And while many men kept close to the centre and saving _nexus_ of these potentially universal themes, others might become absorbed with data of the creature-world, or with the manifold actions of the mind of man, so as to forget to keep all duly ordered and connected with the central thought. So the search for knowledge might roam afield. Likewise as to its motive; practically with many men it was, in itself, a joy and end; although they might continue to connect this end formally with the salvation of the soul. Roger Bacon of a surety was such a one. Another was Albertus Magnus. The laborious culling of twenty tomes of universal knowledge surely had the joy of knowing as the active motive. And Aquinas too; no one could be such an acquisitive and reasoning genius, without the love of knowledge in his soul. Yet Thomas never let this love point untrue to its goal of research and devotion, to wit, sacred doctrine, theology, the Christian Faith in its very widest compass, yet in its unity of saving purpose.
