Lost Island

….they say that there is in the ocean somewhere an island which, because of the difficulty (or rather the impossibility) of finding that which does not exist, some have called the “Lost Island.” And the story goes that it is blessed with all manner of priceless riches and delights in abundance, much more even than the Happy Isles, and, having no owner or inhabitant, it is superior everywhere in abundance of riches to all those other lands that men inhabit. Now, if anyone tell me that it is like this, I shall easily understand what is said, since nothing is difficult about it. But if he should then go on to say, as though it were a logical consequence of this: You cannot any more doubt that this island that is more excellent than all other lands truly exists somewhere in reality than you can doubt that it is in your mind; and since it is more excellent to exist not only in the mind alone but also in reality, therefore it must needs be that it exists. For if it did not exist, any other land existing in reality would be more excellent than it, and so this island, already conceived by you to be more excellent than others, will not be more excellent. If, I say, someone wishes thus to persuade me that this island really exists beyond all doubt, I should either think that he was joking, or I should find it hard to decide which of us I ought to judge the bigger fool—I, if I agreed with him, or he, if he thought that he had proved the existence of this island with any certainty, unless he had first convinced me that its very excellence exists in my mind precisely as a thing existing truly and indubitably and not just as something unreal or doubtfully real. . . .
