Every man and woman who has not denied or falsified nature knows, or at any rate feels, that love, though the least “serious,” is the most significant of all things. The wise do not talk much about this knowledge, for fear of exposing its delicate edge to the stolid resistance of the profligate and unbelieving, and because its light, though, and for the reason that, it exceeds all other, is deficient in definition. But they see that to this momentary transfiguration of life all that is best in them looks forward or looks back, and that it is for this the race exists, and not this for the race--the seed for the flower, not the flower for the seed. All religions have sanctified this love, and have found in it their one word for and image of their fondest and highest hopes; and the Catholic has exalted it into a “great Sacrament,” holding that, with Transubstantiation--which it resembles--it is only unreasonable because it is above reason. “The love which is the best ground of marriage,” writes also the Protestant and “judicious” Hooker, “is that which is least able to render a reason for itself.” Indeed, the extreme unreasonableness of this passion, which gives cause for so much blaspheming to the foolish, is one of its surest sanctions and a main cause of its inexhaustible interest and power; for who but a “scientist” values greatly or is greatly moved by anything he can understand--that which can be comprehended being necessarily less than we are ourselves? In this matter the true poet must always be a mystic--altogether to the vulgar, and more or less to all who have not attained to his peculiar knowledge. For what is a mystery but that which one does not know? The common handicrafts used to be called mysteries; and their professors were mystics to outsiders exactly in the sense that poets or theologians, with sure, but to them uncommunicated and perhaps incommunicable, knowledge, are mystics to the many. The poet simply knows more than they do; but it flatters their malignant vanity to call him names which they mean to be opprobrious, though they are not, because he is not such a spiritual pauper as themselves. But poets are mystics, not only by virtue of knowledge which the greater part of mankind does not possess, but also because they deal with knowledge against which the accusation of dunces who know the differential calculus is etymologically true--namely, that it is _absurd_. Love is eternally absurd, for that which is the root of all things must itself be without root. Aristotle says that things are unintelligible to man in proportion as they are simple; and another says, in speaking of the mysteries of love, that the angels themselves desire in vain to look into these things.
