Standards for brute facts and rejections. About nonsense.
[1] nonsenses are only in language.
[2] roughly speaking, "x is y" presupposes an x that is y.
[3] "x is" means "x is itself", "an x that is not itself" is nonsense.
[3.1] while "x is itself" means no more than x - or, in language, means "x" is not nonsense.
[3.2] "x is not at all while x is itself" is one of the nonsenses (there is a certain absurdity in saying "x does not subsist at all while x is itself").
[3.3] "x happens to be" and "x could be not x" (x could be otherwise) are some of the nonsenses, as it means "x happens to be x".
[3.4] "there is no x" means "x" is nonsense.
[4] "x is y" when it is not is thus nonsense, as "an x that is y" is nonsense here.
So "Being" and "false but not nonsense" and "possible" are some of the nonsenses.
[5] there is no deduction from nonsense.
[5.1] we do not posit an arbitrary "x is y" as brute then deduce from it, for it has not been shown to not be nonsense.
[6] so brute facts name the world.
[7] there is thus no philosophical rejection that is not of the form "this is nonsense", because otherwise one is rejecting a name.
