What then is the reason of this?  The reason is that we have never read for this purpose, we have never written for this purpose, so that we may in our actions use in a way conformable to nature the appearances presented to us; but we terminate in this, in learning what is said, and in being able to expound it to another, in resolving a syllogism, and in handling the hypothetical syllogism.  For this reason where our study (purpose) is, there alone is the impediment.  Would you have by all means the things which are not in your power?  Be prevented then, be hindered, fail in your purpose.  But if we read what is written about action (efforts, [Greek:  hormae]), not that we may see what is said about action, but that we may act well; if we read what is said about desire and aversion (avoiding things), in order that we may neither fail in our desires, nor fall into that which we try to avoid; if we read what is said about duty (officium), in order that remembering the relations (of things to one another) we may do nothing irrationally nor contrary to these relations; we should not be vexed, in being hindered as to our readings, but we should be satisfied with doing the acts which are conformable (to the relations), and we should be reckoning not what so far we have been accustomed to reckon:  To-day I have read so many verses, I have written so many; but (we should say), To-day I have employed my action as it is taught by the philosophers; I have not employed my desire; I have used avoidance ([Greek:  echchlisei]) only with respect to things which are within the power of my will; I have not been afraid of such a person, I have not been prevailed upon by the entreaties of another; I have exercised my patience, my abstinence, my co-operation with others; and so we should thank God for what we ought to thank him.

There is only one way to happiness, and let this rule be ready both in the morning and during the day and by night:  the rule is not to look towards things which are out of the power of our will, to think that nothing is our own, to give up all things to the Divinity, to Fortune; to make them the superintendents of these things, whom Zeus also has made so; for a man to observe that only which is his own, that which cannot be hindered; and when we read, to refer our reading to this only, and our writing and our listening.  For this reason I cannot call the man industrious, if I hear this only, that he reads and writes; and even if a man adds that he reads all night, I cannot say so, if he knows not to what he should refer his reading.  For neither do you say that a man is industrious if he keeps awake for a girl, nor do I. But if he does it (reads and writes) for reputation, I say that he is a lover of reputation.  And if he does it for money, I say that he is a lover of money, not a lover of labor; and if he does it through love of learning, I say that he is a lover of learning.  But if he refers his labor to his own ruling power that he may
