None of these things ought to be called a man's, which do not belong to a man, as man. They are not required of a man, nor does man's nature promise them, nor are they the means of man's nature attaining its end. Neither then does the end of man lie in these things, nor yet that which aids to the accomplishment of this end, and that which aids towards this end is that which is good. Besides, if any of these things did belong to man, it would not be right for a man to despise them and to set himself against them; nor would a man be worthy of praise who showed that he did not want these things, nor would he who stinted himself in any of them be good, if indeed these things were good. But now the more of these things a man deprives himself of, or of other things like them, or even when he is deprived of any of them, the more patiently he endures the loss, just in the same degree he is a better man.
In one respect man is the nearest thing to me, so far as I must do good to men and endure them. But so far as some men make themselves obstacles to my proper acts, man becomes to me one of the things which are indifferent, no less than the sun or wind or a wild beast. Now it is true that these may impede my action, but they are no impediments to my affects and disposition, which have the power of acting conditionally and changing: for the mind converts and changes every hindrance to its activity into an aid; and so that which is a hindrance is made a furtherance to an act; and that which is an obstacle on the road helps us on this road.
Thou canst pass thy life in an equable flow of happiness, if thou canst go by the right way, and think and act in the right way. These two things are common both to the soul of God and to the soul of man, and to the soul of every rational being, not to be hindered by another; and to hold good to consist in the disposition to justice and the practice of it, and in this to let thy desire find its termination.
Both man and God and the universe produce fruit; at the proper seasons each produces it. But if usage has especially fixed these terms to the vine and like things, this is nothing. Reason produces fruit both for all and for itself, and there are produced from it other things of the same kind as reason itself.
Remember that this which pulls the strings is the thing which is hidden within: this is the power of persuasion, this is life, this, if one may so say, is man. In contemplating thyself never include the vessel which surrounds thee and these instruments which are attached about it. For they are like to an axe, differing only in this that they grow to the body. For indeed there is no more use in these parts without the cause which moves and checks them than in the weaver's shuttle, and the writer's pen and the driver's whip.
