These can be recognised from the list of genuinely weighty reasons given above, but they may seem to be just, though they are not, unless they are duly investigated. For instance, the claim for a period of abstinence needed after childbirth, wives' passing ailments, wastage of reproductive powers, whether due to these or not, the polygamy allowed to the Israelites, and other such reasons which are without merit from the point of view of justice. These reasons are invented by husbands after they have become frigid, when unchaste lusts have robbed them of conjugial love and infatuated them with the notion that it is similar to scortatory love. These men on taking a concubine make false and deceptive reasons of this sort into true and genuine ones to avoid ill-repute; they mostly spread around lying rumours about their wives, and good will makes their friends among their fellow-citizens accept these as true and embroider them.
