Anselm argued that an ideal being is important to exist. during this argument God is an excellent being thus he should exist that is understood because of the ontological argument. Guanilo thought this argument was absurd and he viewed the other. one thing doesn't exist simply because it's excellent and he used the instance of an ideal island. The island is ideal thus in step with Anselm's view it ought to exist however the island stop to exist thus Guanilo planned this argument to be reductio ad absurdum. as compared they each agree that as a result, of one thing is ideal it doesn't exist however in distinction saint believed that God was an exception to the present because God is a whole totally different matter and Gaunilo doesn't believe God is an exception to the present view, though he Guanilo believes in God he doesn't consider the ontological argument as proof of Gods existence.
A giffen good is a good whose demand rises when the price rises, which is opposite to the laws of demand because the laws of demand state that a rise in price will result in a reduction of demand. An example can be a staple food like bread. If the price of bread rises, people will buy it more because they'll have to cut back on other more expensive things, of course this applies in theory.
