（12分）阅读下列材料：

材料一 ：“治民无常，唯以法治……明主之所制其臣者，二柄而已矣。二柄者，刑德也。何谓刑德？曰：杀戮之谓刑，庆赏之谓德。为人臣者畏诛罚而利庆赏……故法者，王之本也。” 

——《韩非子》

材料二：“在罗马人那里，私有制和私法的发展没有在工业和贸易方面引起进一步的后果，因为他们的生产方式没有改变。”但当资本主义经济在封建社会内部逐渐发展起来时，“详细拟定的罗马法便立即得到恢复并重新取得威信。”

——《马克思恩格斯全集》

材料三： 罗马法为后世提供了宝贵的参考经验。罗马共和国特设一种审理公职人员贪赃枉法、以权谋私等重大刑事案件的法院，实质上就是陪审法院。罗马实行一种“保护人制度”。保护人可以替被告发言，反驳控告人提出指控。罗马法中有句名言，即“没有告诉人就没有法官”。

材料四： 法律与道德作为上层建筑的组成部分，都是维护社会秩序、规范人们思想和行为的重要手段，……法治以其权威性和强制手段规范社会成员的行为，德治以其说服力和劝导力提高社会成员的思想认识和道德觉悟。道德规范和法律规范应该互相结合，统一发挥作用。
