In simpler phrase, unless the vision and conviction are to be trusted, unless, to revert to Mr. Santayana’s former words, the soul’s “invincible surmise” be taken as truth, that which we know as truth is but a phantasm. The sonnet sequence is the intimate record of an individual soul in its evolving spiritual life, and has the significance belonging only to art which interprets a personality, an experience, in whose development one finds some clew to his own labyrinth. It reveals the many phases of speculation, reflection, questioning, through which one passes in the transition from beliefs indoctrinated in the mind at its earliest consciousness, to convictions which follow thought liberated by life, by intimacy with nature, and by recognition of its own spiritual authority. It is the winning of this conviction, with its attendant seeking and unrest, allayed by draughts from the wayside springs of beauty, memory, and imagination,—which comprises the record of the first sonnet sequence, whose conclusions, as “strewn thoughts” springing along the way, are gathered into a final chaplet for the brows of the “Eternal Mother,” Nature, whose peace he sought when he came down from Golgotha, and whose larger meaning, synonymous with the primal freedom of the soul, is conveyed in the sonnet: These strewn thoughts, by the mountain pathway sprung, I conned for comfort, till I ceased to grieve, And with these flowering thorns I dare to weave The crown, great Mother, on thine altar hung. Teach thou a larger speech to my loosed tongue, And to mine opened eyes thy secrets give, That in thy perfect love I learn to live, And in thine immortality be young. The soul is not on earth an alien thing That hath her life’s rich sources otherwhere; She is a parcel of the sacred air. She takes her being from the breath of Spring, The glance of Phœbus is her fount of light, And her long sleep a draught of primal night. Aside from Mr. Santayana’s philosophical sonnets he has a second sequence, upon love, which, too, is philosophically tinged. In the matter of beauty this is perhaps the more finished and artistic work; but I have chosen rather to dwell upon the subtlety of his speculations in those phases of thought less universally treated of by poets than is love. It has not been possible, however, to follow the sequence in its order, or to present more than certain individual notes of its philosophy.
