The knower paradox concerns a sentence such as, "This sentence is unknown." Now liar sentences can be paired with honest sentences, e.g. "This sentence is true." So suppose there was a sentence that goes, "This sentence is known."
Curry's paradox can involve conditional sentences whose antecedents resemble honest sentences. Is it possible to fuse an honest-knower sentence with the informal structure of a Curry sentence to yield an additional enigmatic sentence? What I mean is, can a paradox be derived from, "If this sentence is known, then φ," where φ is an arbitrary sentence/logical explosion?
Or consider liar cycles such as
A. Sentence B is true.
B. Sentence A is false.
What happens if we switch out "is true/false" for "is known/unknown"? Do we end up with another species of knower paradox?
I also wonder about Yablo's paradox, here. Generally, can we expand upon the knower paradox by combining it with other paradoxes?
