of pity and helpfulness towards all suffering which marks the man of God, are as far removed from the physical attraction of sex for sex, and the mere liking of the eye and ear, as is the intellectual power of the sage from the vulpine cunning of the savage.  “For,” as Emerson well said, “it is a fire that, kindling its first embers in the narrow nook of a private bosom, caught from a wandering spark out of another heart, glows and enlarges until it warms and beams upon multitudes of men and women, upon the universal heart of all, and so lights up the world and all nature with its generous flames.”  Both love and reason alike pass through stage after stage, always away from the particularity of selfishness and ignorance, into larger and larger cycles of common truth and goodness, towards the full realization of knowledge and benevolence, which is the inheritance of emancipated man.  In this transition, the sensuous play of feeling within man, and the sensitive responses to external stimuli, are made more and more organic to ends which are universal, that is, to spiritual ends.  Love, which in its earliest form, seems to be the natural yearning of brute for brute, appearing and disappearing at the suggestion of physical needs, passes into an idealized sentiment, into an emotion of the soul, into a principle of moral activity which manifests itself in a permanent outflow of helpful deeds for man.  It represents, when thus sublimated, one side at least of the expansion of the self, which culminates when the world beats in the pulse of the individual, and the joys and sorrows, the defeats and victories of mankind are felt by him as his own.  It is no longer dependent merely on the incitement of youth, grace, beauty, whether of body or character; it transcends all limitations of sex and age, and finds objects on which it can spend itself in all that God has made, even in that which has violated its own law of life and become mean and pitiful.  It becomes a love of fallen humanity, and an ardour to save it by becoming the conscious and permanent motive of all men.  The history of this evolution of love has been written by the poets.  Every phase through which this ever-deepening emotion has passed, every form which this primary power has taken in its growth, has received from them its own proper expression.  They have made even the grosser instincts lyric with beauty; and, ascending with their theme, they have sung the pure passion of soul for soul, its charm and its strength, its idealism and heroism, up to the point at which, in Browning, it transcends the limits of finite existence, sheds all its earthly vesture, and becomes a spiritual principle of religious aspiration and self-surrender to God.
