That which leads to true truth-apt assent is [1] demonstration; untrue truth-apt assent is [2] sophistry. That which leads to truth-apt assent not taken as true or false but rather as [a matter of] common consent (‘umûm al-i‘tirâf) is—if it's like this—[3] dialectic (jadal), otherwise it's eristic (shaghab) which is, along with sophistry (safsata), under one kind of fallacy production (mughâlata).  [And what leads] to overwhelming though not truth-apt assent is [4] rhetoric; and to evocation of images rather than assent, [5] poetry (Tûsî Sharh al-Ishârât [1971] 460.1–461.12).
