Around these 3 questions , the paper chooses respectively the representative delegates of different approaches : naturalism , antinaturalism , and pluralism . in this process , i focus on refuting the arguments which believe social laws are either impossible , impractical , or ungainable . finally , i aim to find a way to mitigate those arguments : to weaken the concept of laws to unify laws and rules , and by this way do i want to support the coexistence of different methodologies 本文以這三個問題為中心,挑選自然主義、反自然主義及多元論的幾位典型代表人物的觀點來展開論述,重點在于反駁堅持社會科學規律不存在、不實際或不可獲得的觀點,為化解關鍵爭論找到一個途徑:弱化“規律”概念,融規律與規則于一體,以期將此作為支持不同方法論的存在的突破口。
