《熙德》是古典主义悲剧大师高乃依的代表作，关于这部悲剧的主题意蕴，长期以来学界争论不休。我们认为该剧的主题表现为人的理性和感情较量。该剧在当时由于被认为违反了古典主义的戏剧创作原则而遭到攻击，实际上高乃依本人既恪守原则而又对之加以灵活运用。 “Elder” is a masterpiece of the classical tragedy master Gaunei. The subject matter of the tragedy has long been debated in the academic circle. We think the main theme of the play is man’s rational and emotional contest. The play was attacked at the time because it was considered to violate the classicist principle of dramatic writing. In fact, Gauna himself applied both principle and principle.
