Putting those words together might be mistaken as an assertion, but
they no more make up an assertion than the sentence: "Take out
the garbage." Or, "Take out the garbage is not true." The first
sentence is semantically acceptable but not the second and
certainly your sentence is not semantically acceptable. They are
gibberish. Of course, we can fool all of the mathematicians
and logicians all of the time because they only make up some
of the people. But they will insist that they are correct and this
statement I am making is not true.
