Morality, among other themes are expressed through the satirical work of Jonathan Swift, among them Gulliver's Travels. One of the overriding moral themes that comes from this work is the idea of might versus right. In other words, should someone's personal life be ruled by those who have the power to enforce their own belief system? Gulliver deals with this in Lilliput and in Brobdingnag, as well as in the chaining of the Yahoos by the Houyhnhnms.
