A statement is a sentence that has a reality worth, either true or false. Several kinds of sentences are not statements – concerns and regulates, for circumstances – because they carry out not have actually truth values. Another kind of sentence that is not a statement can be called nonfeeling.

You are watching: Everything i say is a lie

Nonsense sentences are not statements for the same reason as inquiries and also commands; they cannot be shelp to be true or false. Tbelow are two kinds of nonfeeling sentences that we typically encounter in studies of logic.

1.) First are sentences in which the words have actually no meaning, and thus cannot be said to communicate reality. A classical example is the Lewis Carroll poem “The Jabberwocky” which starts,

T’was brillig and the slithy toves did gire and gimble in the wabe.

This appears to be a sentence; it has actually a subject and predicate, and also the words can be figured out as to their components of speech. But it cannot be said to be true or false, and for this reason we call it nonsense.

2.) Then tbelow are sentences in which the reality worth is impossible to nail down. The traditional instance for this type is

This sentence is false.

This certain looks choose a statement. But what is its truth value? Is it true? If so, then it is false, as it claims. But is it false? Then it is false that it is false, and also therefore true. You check out that a reality value cannot be applied to this sentence in any kind of settled method.

Comparable problems take place through the liar paradox: Were someone to case, “Everything I say is a lie,” is that sentence likewise a lie? The apostle Paul touches on this as soon as he quotes a Cretan saying that Cretans are always liars (Titus 1:12).

Tright here is additionally the story of the missionary caught by cannibals who sentence him to fatality but give him a selection of approaches, saying, “If you tell us something true, we will certainly boil you in oil. If you tell us somepoint false, we will burn you at the stake.” The missionary, who had actually thankfully studied his logic, responded, “You will burn me at the stake.”

Think around it.
