The motivation for dedicating a separate classification to the science of dialectic, even though it is a branch of the sciences of reasoning and dispute, was...
that since the field of debate in rejection and acceptance was wide, and each debater in reasoning and answering would let loose his reins in argumentation, some of it being correct and some incorrect,
the scholars needed to establish etiquette and rules that debaters must adhere to in rejection and acceptance,
and how the condition of the reasoner and respondent should be, when it is permissible for them to be reasoning, and how one becomes refuted and silenced,
the place of their objections or oppositions, and where one must remain silent while their opponent speaks and reasons.
Ibn Khaldun said this.
Shaykh al-Islam Ibn Taymiyyah described this phase with a description that reveals its nature, characteristics, and advantages and disadvantages,
and he said: "Then later generations debated forms of interpretation and analogy that influence the thinking of some,
although upon closer examination it leads to nothing, they would only accept from debate what was beneficial, even if it gave only a weak impression to the observer.
