So today I am in my Theory of knowledge class at my high school and my teacher presents Epimenides paradox. At first I was excited but then I noticed something. the statement that he put up was "All cretans are liars." This statement fails to address that liars lie all the time. I feel as though if the statement read "All cretans are always lying." or even "Cretans always lie." then the statement would truly be a paradox.
If we consider the statement my teacher showed us, "All Cretans are liars" then we can say that this Cretan wasn't lying at this point in time, he could possibly be telling the truth. I feel like since we can say that the Cretan may be or may not be lying it isn't a paradox.
I got into an argument with my teacher about this and he wouldn't let me talk aside from when I said that it wasn't really a paradox. He was stuck on his ideas. I am completely okay with being wrong I just don't see any logical argument saying that the statement is truly a paradox.
Can someone please let me know?
