In his
preface, Aquinas says he is writing to instruct beginners. Perhaps this is why whenever I come to the Summa, I feel like a beginner. Or perhaps Aquinas is calling everyone a beginner, calling everyone to begin. The endless pondering of God's self-revelation is a task we must have the humility and confidence to begin again, and again, ad infinitum.
Aquinas criticizes his less remembered contemporaries for not following "the order of the subject matter." It's probably fair to say that written works which survive, which are loved and remembered and returned to, tend to follow a definite order. Yet Aquinas claims more than a definite order for the Summa. He claims that, in the Summa, he expounds sacred doctrine "as briefly and clearly as the matter itself may allow." On some questions I think he really has done this. Even so, this is a bold claim for an author to make about his own work. It would be an interesting experiment to try to rewrite articles from the Summa in order to improve their brevity and clarity and see whether, after finishing, the revisions were actual improvements. Or more broadly, to reorganize the parts of the Summa itself. I imagine one could learn a lot even by failing at such a task.
Aquinas's other criticism of his contemporaries is that they multiply useless articles, questions, and arguments. This means, I suppose, the multiplication of articles, questions, and arguments in the Summa—I haven't counted how many articles he has—are not useless multiplications but rather demanded by the subject-matter itself. I'll have to re-examine this question after I finish re-reading the Summa.
