When, therefore, any one, upon being reproved, affirms that Fate is the cause of the action, and insists that therefore he is not to be blamed, because he says that under the compulsion of Fate he did the action which is censured, let him come back to apply this to his own case, let him observe this principle in managing his own affairs: let him not chastise a dishonest servant; let him not complain of a disrespectful son; let him not utter threats against a mischievous neighbour. For in doing which of these things would he act justly, if all from whom he suffers such wrong are impelled to commit it by Fate, not by any fault of their own? If, however, from the fight inherent in himself, and the duty incumbent on him as the head of a family towards all whom for the time he has under his control, he exhorts them to do good, deters them from doing evil, commands them to obey his will, honours those who yield implicit obedience, inflicts punishment on those who set him at naught, gives thanks to those who do him good, and hates those who are ungrateful,--shall I wait to prove the absurdity of the astrologers calculations of Fate, when I find him proclaiming, not by words but by deeds, things so conclusive against his pretensions that he seems to destroy almost with his own hands every hair on the heads of the astrologers?

If your eager desire is not satisfied with these few sentences, and demands a book which will take longer time to read on this subject, you must wait patiently until I get some respite from other duties; and you must pray to God that He may be pleased to allow both leisure and capacity to write, so as to set your mind at rest on this matter. I will, however, do this with more willing readiness, if your Charity does not grudge to remind me of it by frequent letters, and to show me in your reply what you think of this letter.
