Sentences that are not capable of being either true or false are called nonsense, e.g. "quadruplicity drinks procrastination" or "Socrates is a man is a man"
I want to say "The Chinese language is incapable of conveying Western philosophy; dialectical materialism is actually nonsense in Chinese."
The best I can do is this: "汉语无力承载西方哲学；辩证唯物主义用汉语讲没有意义。"
But it doesn't seem to scratch where it itches.
