The first factor I will talk about is the truth of the sentence. The sentences contradict one another because on the one sentence it says that the Sphinx is an unreal creature whereas on the other one it says that it exist and an unreal thing cannot exist if you look at the definition of both terms .e.g.
Unreal= lacking in truth, not actual
Exist= to have an actual being
Thus the sentence encompasses a false sense or lacks the truth.
In the matter of sense we can fully make sense of the Sphinx and imagine it although it is non-existent in real life and even though it doesn’t have a referent in the real world.
The second and third sentences have entailment since they claim that “it (Sphinx) exists because it has been imagined and in an infinite world (our minds or conscious body, according to my understanding) everything that can be imagined must exist somewhere so in a sense the first sentence entails the second one and thus they are both true.
In the case of paradox one can say that the second last sentence encompasses in it since one cannot really tell wether it is true or not, there is no way on distinguishing the true value.
In the text below we have mostly 1st person pronouns which are deitic and bound
.e.g. “I thought you’d be smaller,” (I = deitic and bound) because I in the sentence refers to (Teppic) the person talking in the sentence thus you look at the context to see that
We also have 2nd person pronouns which are also mostly deitic and bound
.e.g. “You’re a Sphinx” (You – deitic and bound) because the you refers to the Sphinx which is also involved in the conversation and thus also you look at the context to find that.
We have a 3rd person pronoun also
.e.g. “They don’t do you justice,” (They = deitic and free) because it refers to the above mentioned statues, thus you need to know what is being talked about in order for you to be able to analyse the sentence.
We also have a reflexive pronoun in the sentence “ It dawned on the Sphinx...
