Spinoza was the great pantheist, whose name is still a terror to the orthodox, and whose philosophy is--very properly--a horror to the Church--and yet Spinoza never wrote a line that, to the unguided student, sounds more Spinozist than the words of Saint Gregory and Archbishop Hildebert. If God is everywhere; wholly; presiding, sustaining, embracing and filling, "sursum regens, deorsum continens," He is the only possible energy, and leaves no place for human will to act. A force which is "one and the same and wholly everywhere" is more Spinozist than Spinoza, and is likely to be mistaken for frank pantheism by the large majority of religious minds who must try to understand it without a theological course in a Jesuit college. In the year 1100 Jesuit colleges did not exist, and even the great Dominican and Franciscan schools were far from sight in the future; but the School of Notre Dame at Paris existed, and taught the existence of God much as Archbishop Hildebert described it. The most successful lecturer was William of Champeaux, and to any one who ever heard of William at all, the name instantly calls up the figure of Abelard, in flesh and blood, as he sang to Heloise the songs which he says resounded through Europe. The twelfth century, with all its sparkle, would be dull without Abelard and Heloise. With infinite regret, Heloise must be left out of the story, because she was not a philosopher or a poet or an artist, but only a Frenchwoman to the last millimetre of her shadow. Even though one may suspect that her famous letters to Abelard are, for the most part, by no means above scepticism, she was, by French standards, worth at least a dozen Abelards, if only because she called Saint Bernard a false apostle. Unfortunately, French standards, by which she must be judged in our ignorance, take for granted that she philosophized only for the sake of Abelard, while Abelard taught philosophy to her not so much because he believed in philosophy or in her as because he believed in himself. To this day, Abelard remains a problem as perplexing as he must have been to Heloise, and almost as fascinating. As the west portal of Chartres is the door through which one must of necessity enter the Gothic architecture of the thirteenth century, so Abelard is the portal of approach to the Gothic thought and philosophy within. Neither art nor thought has a modern equivalent; only Heloise, like Isolde, unites the ages.
