Causing any damage or harm to one party in order to help another party is not justice, and likewise, attacking all feminine conduct [in order to warn men away from individual women who are deceitful] is contrary to the truth, just as I will show you with a hypothetical case. Let us suppose they did this intending to draw fools away from foolishness. It would be as if I attacked fire -- a very good and necessary element nevertheless -- because some people burnt themselves, or water because someone drowned. The same can be said of all good things which can be used well or used badly. But one must not attack them if fools abuse them.
Some people would regard people who look like they do as ugly if they did not look like them.
Yet if women are so flighty, fickle, changeable, susceptible, and inconstant (as some clerks would have us believe), why is it that their suitors have to resort to such trickery to have their way with them? And why don't women quickly succumb to them, without the need for all this skill and ingenuity in conquering them? For there is no need to go to war for a castle that is already captured.
Those who plead their cause in the absence of an opponent can invent to their heart's content, can pontificate without taking into account the opposite point of view and keep the best arguments for themselves, for aggressors are always quick to attack those who have no means of defence.
