A review of Vico's concept ion of jurisprudence -A study of Vico's "Institutiones Oratoriae"

维柯的法理学概念旨在在多种情况下实现自然公平。以下是他认为最适合的推理方法。(1)充分运用“ingenium”，归纳地发现适当的媒介，即在两个显然不同的事物中发现相似之处的想象力的飞跃。(2)通过“外延法”（epicheirema）强化三段论，即从不同的视角进行推理、证明和其他额外的支持。(3)通过“matabasis”巧妙地操作媒介，即从一个属（或种）过渡到另一个属（或种）。

Vico's conception of jurisprudence aims for the realization of natural equity under a great variety of circumstances. The following are the methods of reasoning which he considers the most suitable for it.(1)the inductive discovery of proper medium by the full using of "ingenium", i.e. the imaginative leap that finds similarity in two things that are apparently dissimilar.(2)the reinforcement of syllogism by "epicheirema", i.e. means of reasons, proofs and other additional supports made from various visual angles.(3)the skillful operation of medium by "matabasis", i.e. the transition from one genus (or species) to another.
