-If we assume that "this sentence" can refer to (1), then the
-proposition expressed by (1) will be true just in case the thing
-referred to by "this sentence is true". Thus (1) will be true just in
-case (1) is true, and (1) is true just in case (1) is true, and so on.
-If (1) is true, then (1) is true; but if (1) is not true, then (1) is
-not true.
