Page "Liar paradox" Paragraph 23

Arthur Prior asserts that there is nothing paradoxical about the liar paradox.

His claim ( which he attributes to Charles Sanders Peirce and John Buridan ) is that every statement includes an implicit assertion of its own truth.

Thus, for example, the statement, " It is true that two plus two equals four ", contains no more information than the statement " two plus two equals four ", because the phrase " it is true that ..." is always implicitly there.

And in the self-referential spirit of the Liar Paradox, the phrase " it is true that ..." is equivalent to " this whole statement is true and ...".
