I am currently reading a paper and the following statement is used:
Fact "A" for individual i happens if and only if condition B is fulfilled for i possibly not, though not necessarily exclusive of, j.
What does this mean? (speficially,the not, though not part)
Thats exactly how its written; I only removed the technicalities. I do not know if it concerns modal logic or if its a typo, but I never came around such statement.
