## 143. The Second Island.

Two native inhabitants A and B of this island stated:

A: We are both liars, and this island is called Maya.

B: What is true is true.

Can we assert that the second island is indeed called Maya?
143. It is clear that A is a liar (the statement made by A cannot belong to a knight). Since B agrees with A, B is also a liar. Since the statement made by A is false, it is not true that: 1) A and B are both liars and that 2) the second island is called Maya. But statement (1) is true, so statement (2) must be false. Therefore, the second island is not the island of Maya.
