Another of the constant precepts of Epictetus is that we should aim high; we are not to be common threads in the woof of life, but like the laticlave on the robe of a senator, the broad purple stripe which gave lustre and beauty to the whole. But how are we to know that we are qualified for this high function? How does the bull know, when the lion approaches, that it is his place to expose himself for all the herd? If we have high powers we shall soon be conscious of them, and if we have them not we may gradually acquire them. Nothing great is produced at once,--the vine must blossom, and bear fruit, and ripen, before we have the purple clusters of the grape,--"first the blade, then the ear, after that the full corn in the ear." But whence are we to derive this high sense of duty and possible eminence? Why, if Caesar had adopted you, would you not show your proud sense of ennoblement in haughty looks; how is it that you are not proud of being sons of God? You have, indeed, a body, by virtue of which many men sink into close kinship with pernicious wolves, and savage lions, and crafty foxes, destroying the rational within them, and so becoming greedy cattle or mischievous vermin; but above and beyond this, "If," says Epictetus, "a man have once been worthily interpenetrated with the belief that we all have been in some special manner born of God, and that God is the Father of gods and men, I think that he will never have any ignoble, any humble thoughts about himself." Our own great Milton has hardly expressed this high truth more nobly when he says, that "He that holds himself in reverence and due esteem, both for the dignity of God's image upon him, and for the price of his redemption, which he thinks is visibly marked upon his forehead, accounts himself both a fit person to do the noblest and godliest deeds, and much better worth than to deject and defile, with such a debasement and pollution as sin is, himself so highly ransomed, and ennobled to a new friendship and filial relation with God." "And how are we to know that we have made progress? We may know it if our own wills are bent to live in conformity with nature; if we be noble, free, faithful, humble; if desiring nothing, and shunning nothing which lies beyond our power, we sit loose to all earthly interests; if our lives are under the distinct governance of immutable and noble laws.
