A great soul, any sincere soul, knows not what he is,—alternates between the highest height and the lowest depth; can, of all things, the least measure—Himself! What others take him for, and what he guesses that he may be; these two items strangely act on one another, help to determine one another. With all men reverently admiring him; with his own wild soul full of noble ardors and affections, of whirlwind chaotic darkness and glorious new light; a divine Universe bursting all into godlike beauty round him, and no man to whom the like ever had befallen, what could he think himself to be?
