法哲學在何種意義上有助於部門法學

法哲學所面對的最大批評在於與部門法學及司法實踐的疏離。部門法學知識的主體是法教義學，而法哲學是關於法的一般哲學理論，兩者間的關係主要體現在疑難案件的場合。在法概念論的層面上，法概念爭議會影響疑難案件中法律規範之效力的認定，這可能但不必然會影響裁判結論，但必然會影響判決的整個論證和說理的思路。在法學方法論的層面上，法律適用基本模式的分歧會造成裁判論證方式上的重要區分，司法哲學立場的差異可能會對相同的案件得出不同的裁判結論。在法倫理學的層面上，規範倫理學立場間的對立會影響個案的裁判後果。總之，法哲學的作用方式是間接的而不是直接的，通常在法教義學框架和體系內發揮作用；它旨在複雜化而非簡化論證，試圖揭示問題背後深層而複雜的理論分歧。

The most serious critique that legal philosophy faces is its alienation from specific laws and judicial practices. While the mainstream tradition of specific laws is that of legal dogmatics, legal philosophy constitutes a general theory of philosophy about law, whose relationship manifests itself clearly in hard cases. In the domain of concept of law, the disputes about concept of law have an impact on the validity of a legal norm, which can, but do not necessarily influence judicial decision, although they will certainly affect the way of argumentation and reasoning in the whole decision procedure. In the domain of legal methodology, the divergence on basic model of legal application makes an important difference in way of judicial argumentation, and the discrepancy in judicial philosophy may lead to different conclusion in the same case. In the domain of legal ethics, the antagonism between different standpoints in normative ethics will have impact on judicial consequences. In short, legal philosophy functions in an indirect way, which usually plays a part in the framework and system of legal dogmatics; and it aims to make the arguments more complicated, not more simplified, which tries to reveal the deep and intricate theoretical disagreements behind the controversies of doctrinal problems.
