"All Cretans are liars."

        The Epimenides saying is a problem in logic. It's an expression which is revealed by the Cretan philosopher Epimenides. He said: "All Cretans are liars". This saying of Epimenides is a paradox. The Epimenides saying is also known as the Cretan Paradox.           

        What makes this saying a paradox? If we agree that "All Cretans are liars", Epimenides is a liar because he is a Cretan. If Epimenides is a liar, the statement "All Cretans are liars" is false. In that case, the statement is both true and false. If we agree that "All Cretans are liars" is false, we can say that Cretan Epimenides tells the truth. Then, the statement "All Cretans are liars" should be true. In that case, a contradictory result occurs. Finally, a statement cannot be both true and false.

        In my opinion; if Epimenides had said "There is at least one Cretan which is righteous", we could not call this statement a paradox. Because if he had said like that, he would have mentioned himself in that statement as a Cretan. Thus, we could say that Epimenides tells the truth and agree with the statement. According to the statement "There is at least one Cretan which is righteous", Epimenides is righteous and Cretans are liars.
