法的規範性，從本質而言，遭遇著過去與未來、期待與行為相互間的宿命衝突。法律必須隨著社會而變遷，但法的規範性卻又必須某種程度的制約社會的現實發展，就此而言，以法之規範性為研究對象的法學，亦同樣無法避免類似的矛盾關係：法學者如何面對、解讀與定性社會變遷，如果只能繼續侷限於自我的認識邏輯與系統的話？法律與現實的關聯性，其實在法學的研究體系中，從來就不是陌生的，不論是法事實與基本權行使之事實要件、立法者之現實觀察義務、評估餘地與法學之評價中立等問題，即是法學思維體系中，原本即存在之方法與工具。妥善加以運用法學中處理社會現實之論述分析方式，特別是引入制。政治經濟學般的外來知識體系，不論是否同意，恐怕皆難以避免。

Basically said that the normativity of law faces a non-avoidable conflict between past and future, expectation and action. Law must change itself with the synchronically steps from the society. But the normativity of law should at the other hand control the real change of society. On this point, it will be suitable to say that the legal research isn't able to avoid the same contradicitional relation. How should the legal system place itself, interpret and definite these changes of society, if it stay only inside its knowing logics and system? The connection between law and social reality is not actually strange to the legal research system, such as legal facts, actual presupposition for basic rights, obligation to observe social reality for the legislative and not the least neutrality from jurisprudence by valuation, which are already the existent method and mechanism by the legal research system. A different approach opposite the old one, such as its opening to the other scientist systems like the political economy, will possibly not to be abanded any more.
