This catalogue, once drawn up, Franklin, reflecting that it would be difficult to fight at the same time thirteen defects and keep his mind on thirteen virtues, had an idea similar to that of Horatius in his combat with the Curiatii: he resolved to fight his enemies one by one; he applied to morality the well-known principle of politicians: "_Divide if thou wilt rule_." "I made a little book," he says, "in which I allotted a page for each of the virtues. I ruled each page with red ink, so as to have seven columns, one for each day of the week, marking each column with a letter for the day. I crossed these columns with thirteen red lines, marking the beginning of each line with the first letter of one of the virtues; on which line, and in its proper column, I might mark, by a little black spot, every fault I found upon examination to have been committed respecting that virtue upon that day. "I determined to give a week's strict attention to each of the virtues successively. Thus, in the first week, my great guard was to avoid even the least offense against _temperance_; leaving the other virtues to their ordinary chance, only marking every evening the faults of the day. Thus, if in the first week I could keep my first line, marked T, clear of spots, I supposed the habit of that virtue so much strengthened, and its opposite weakened, that I might venture extending my attention to include the next, and for the following week keep both lines clear of spots. Proceeding thus to the last, I could get through a course complete in thirteen weeks, and four courses in a year. And, like him, who, having a garden to weed, does not attempt to eradicate all the bad herbs at once, which would exceed his reach and his strength, but works on one of the beds at a time, and, having accomplished the first, proceeds to a second; so I should have, I hoped, the encouraging pleasure of seeing on my pages the progress made in virtue, by clearing successively my lines of their spots; till, in the end, by a number of courses, I should be happy in viewing a clean book, after a thirteen weeks' daily examination." =182. Maxim of Epictetus.=--The wise Epictetus gives us the same advice as Franklin: "If you would not be of an angry temper," he says, "then do not feed the habit. Be quiet at first, then count the days where you have not been angry. You will say: 'I used to be angry every day; now every other day; then every third or fourth day, and if you miss it so long as thirty days, offer a sacrifice to God."[166] He said, moreover: "If you will practice self-control, take, when it is warm and you are thirsty, a mouthful of fresh water, and spit it out again, and tell no one."
