Quite to avoid the term is not possible, inasmuch as the conception certainly includes what is mysterious because unknowable through reason. For it includes a sense of the supreme, a sense of God, who is too great for human reason to comprehend, and therefore a mystery. And it includes a yearning toward God, the desire of Him, and the feeling of love. The last is also mysterious, in that it has not exclusive part with reason, but springs as well from feeling. Yet the essence or nature of this spirit of piety which we would analyse, consists in consciousness of the reality of the object of its yearning or devotion. Not altogether through induction or deduction, but with an irrational immediacy of conviction, it feels and knows its object. In place of the knowledge which is mediated through rational processes, is substituted a conviction upheld by yearning, love’s conviction indeed, of the reality and presence of that which is all the greater and more worthy because it baffles reason. And the final goal attainable by this mystic love is, even as the goal of other love, union with the Beloved. The mystic spirit is an essential part of all piety or religion, which relates always and forever to the rationally unknown, and therefore mysterious. Without a consciousness of mystery, there can be neither piety nor religion. Nor can there be piety without some devotion to God, nor the deepest and most ardent forms of piety, without fervent love of God. This devotion and this love supply strength of conviction, creating a realness of communion with the divine, and an assurance of the soul’s rest and peace therein. But that the intellect has part, Hugo abundantly demonstrates. One must have perceptions, and thought’s severest wrestlings--_cogitatio_ and _meditatio_--before reaching that first stage of wide and sure intelligence, which relates to the creature world, and affords a broad basis of assurance, whence at last the soul shall spring to God. Intellectual perceptions and rational knowledge, and all the mind’s puttings together of its data in inductions and deductions and constructions, form a basis for contemplation, and yield material upon which the emotional side of human nature may exercise itself in yearning and devotion. Herein the constructive imagination works; which is intellectual faculty illuminated and impelled by the emotions.
