Then, in examining his counsel, he must truly tell his tale; he must consider whether the thing he proposes to do be reasonable, within his power, and acceptable to the more part and the better part of his counsellors; he must look at the things that may follow from that counselling, choosing the best and waiving all besides; he must consider the root whence the matter of his counsel is engendered, what fruits it may bear, and from what causes they be sprung. And having thus examined his counsel and approved it by many wise folk and old, he shall consider if he may perform it and make of it a good end; if he be in doubt, he shall choose rather to suffer than to begin; but otherwise he shall prosecute his resolution steadfastly till the enterprise be at an end. As to changing his counsel, a man may do so without reproach, if the cause cease, or when a new case betides, or if he find that by error or otherwise harm or damage may result, or if his counsel be dishonest or come of dishonest cause, or if it be impossible or may not properly be kept; and he must take it for a general rule, that every counsel which is affirmed so strongly, that it may not be changed for any condition that may betide, that counsel is wicked.
