The west façade is an accepted classic, "an architectural glory of France," irreproachable. Once the intelligence has grasped its pre-eminence, allegiance to it will never waver. The frontispieces of Rheims and of Rouen are richer and may appeal more to the imagination. It is possible that the severe dignity of Paris may even chill at first. But what clarity of plan! Four strong buttresses accentuate the big square parallelogram. Excess of ornamentation has been avoided in order that the whole may stand forth. Lest the two towers might appear to rise abruptly from the massive, some master hand made there the graceful open colonnade.[74]
The façade of Notre Dame is true to its epoch in its appeal to the intellect rather than to the emotions. It was built in the golden age of scholasticism, when religion and philosophy went hand in hand, when the teachers in the schools of Paris, the _cité lettré_, the _oeil du monde_, thought that Faith and Reason could give mutual aid one to the other, that the truths of Revelations could coincide with the natural judgment.
Scholasticism has been belittled by the modern sophists from the time of the XVIII-century Encyclopædist to the XIX-century superman. Yet scholasticism was an important factor in the formation of the French intellect, which, in its virile youth, it put through a course of useful mental gymnastics. Precisely the race, whose ancestors sharpened their wits in the _Sic-et-Non_ debates of the mediæval schools of Paris, is to-day pre-eminent in precision of language and freedom from fogginess of thought. Easy enough for the modern mind to ridicule the quarrel of generations over nominalism and realism, pursued with the personal heat of a modern political campaign.[75] Certainly the abuse of the scholastic system led to hair-splitting disputes, for the deductive method, when carried to excess, ends in thin subtlety. But why judge a system by its extremes? Because XIV-century architecture grew rigid with set formulas and the abuse of its own laws, does that discredit the virile period to which it succeeded?
The bishops who built Notre Dame were notable scholastics. The generations who built cathedrals were impregnated with the certainty that what was Christian was rational. Scholasticism produced St. Thomas Aquinas, whose philosophy has outlived a dozen systems, whose _Summa_ was placed on the assembly table of the Council of Trent, the sole companion of the Scriptures, Aquinas, whose sanity of ethics and doctrine was held up by Leo XIII as the best guide amid current errors.
