Dennis Hackethal criticized idea #2593.
#2593·Zelalem MekonnenOP revised about 1 month agoIf you're not certain which part of your knowledge is true, then there is no difference between what I said and what you said. Because you knew a certain part of your knowledge was true, but it turned out not to be after further inquiry.
Now you’re using the word ‘certain’ with two different meanings, which is confusing. You could replace the second instance, “a certain”, with ‘some’ or just ‘a’.
