The commentary distinguishes the practitioner and the practice:
Sophist (sūfisṭāʾī) — one using pseudo-learned argument against a philosopher.
Wrangler (mushāghib) — one using contentious and deceptive argument in another setting.
Fallacious arguer (mughāliṭ) — one seeking to mislead through reasoning.
An argument may be long, orderly and rhetorically confident without being sound. Both credible premises and valid entailment must be examined.
