Was it the problem of his own life--that concerning the conduct of high, intellectual and spiritual powers--which Browning transferred to his art, creating personages other than himself to be exponents of his theme? We cannot tell; but the problem in varied forms persists from poem to poem. The poet imagined as twenty years of age, who makes his fragment of a confession in _Pauline_, is more than a poet; he is rather of the Sordello type than of the type represented in Eglamor and Aprile.[13] Through his imagination he would comprehend and possess all forms of life, of beauty, of joy in nature and in humanity; but he must also feel himself at the centre of these, the lord and master of his own perceptions and creations; and yet, at the same time, this man is made for the worship and service of a power higher than self. How is such a nature as this to attain its true ends? What are its special dangers? If he content himself with the exercise of the subordinate faculties, intellectual dexterity, wit, social charm and mastery, he is lost; if he should place himself at the summit, and cease to worship and to love, he is lost. He cannot alter his own nature; he cannot ever renounce his intense consciousness of self, nor even the claim of self to a certain supremacy as the centre of its own sympathies and imaginings. So much is inevitable, and is right. But if he be true to his calling as poet, he will task his noblest faculty, will live in it, and none the less look upward, in love, in humility, in the spirit of loyal service, in the spirit of glad aspiration, to that Power which leans above him and has set him his earthly task. Such reduced to a colourless and abstract statement is the theme dealt with in _Pauline_. The young poet, who, through a fading autumn evening, lies upon his death-bed, has been faithless to his high calling, and yet never wholly faithless. As the pallid light declines, he studies his own soul, he reviews his past, he traces his wanderings from the way, and all has become clear. He has failed for the uses of earth; but he recognises in himself capacities and desires for which no adequate scope could ever have been found in this life; and restored to the spirit of love, of trust, by such love, such trust as he can give Pauline, he cannot deny the witnessing audible within his own heart to a future life which may redeem the balance of his temporal loss. The thought which plays so large a part in Browning's later poetry is already present and potent here.
