Perhaps under the shadow of the storm that menaced all Friars, Bonaventure, the Franciscan, grew into so great a friendship with Thomas the Dominican, that their contemporaries compared them to David and Jonathan. The point is of some interest; because it would be quite easy to represent the Franciscan and the Dominican as flatly contradicting each other. The Franciscan may be represented as the Father of all the Mystics; and the Mystics can be represented as men who maintain that the final fruition or joy of the soul is rather a sensation than a thought. The motto of the Mystics has always been, "Taste and see." Now St. Thomas also began by saying, "Taste and see;" but he said it of the first rudimentary impressions of the human animal. It might well be maintained that the Franciscan puts Taste last and the Dominican puts it first. It might be said that the Thomist begins with something solid like the taste of an apple, and afterwards deduces a divine life for the intellect; while the Mystic exhausts the intellect first, and says finally that the sense of God is something like the taste of an apple. A common enemy might claim that St. Thomas begins with the taste of fruit and St. Bonaventure ends with the taste of fruit. But they are both right; if I may say so, it is a privilege of people who contradict each other in their cosmos to be both right. The Mystic is right in saying that the relation of God and Man is essentially a love-story; the pattern and type of all love-stories. The Dominican rationalist is equally right in saying that the intellect is at home in the topmost heavens; and that the appetite for truth may outlast and even devour all the duller appetites of man.
