Metaphysics: The Fundamentals p.241

Aristotle claimed that to deny metaphysics is to do metaphysics. We have seen some reason to agree with Aristotle. The arguments against metaphysics, whether Anti-Realist, Lightweight Realist, Skeptical, or Fictionalist, are all based on certain conceptions about truth, meaning, knowledge, and explanation that inevitably raise metaphysical questions.
