From a purely mathematical or logical perspective, the statement "nothing starts with 'n' and ends with 'g'" can be analyzed using set theory and logic. Here's how:
Definition of the Set: Let's define a set S as the set of all English words that start with the letter 'n' and end with the letter 'g'.
Membership in the Set: The word "nothing" is a member of set S because it starts with 'n' and ends with 'g'. Therefore, "nothing"∈"nothing"∈S.
Truth Value of the Statement: The statement "nothing starts with 'n' and ends with 'g'" can be interpreted as: "The word 'nothing' is a member of the set S". This statement is true, as established in point 2.
Logical Form: If we were to express this in logical form, it might look something like: ∀(∈ ⟺ starts with ’n’ and ends with ’g’)∀x(x∈S⟺x starts with ’n’ and ends with ’g’)"nothing"∈"nothing"∈S
The play on words in the riddle comes from the dual meaning of "nothing." In one sense, "nothing" can mean the absence of something, but in this context, it's referring to the actual word "nothing." Mathematically, the statement is true because the word "nothing" does belong to the set of words that start with 'n' and end with 'g'.
