當今現實主義理論學派正面臨著一種淺碟化的危機，伴隨而來的是現實主義深遠的傳統根基遭受簡化以及忽視。本文企圖藉由重新檢驗現實主義傳統的古典文獻，提出在現實主義中的許多被忽略的問題。本文重新定位與評析現實主義之主要理論傳統，包括修昔底德傳統、奧古斯丁傳統、馬基維利傳統、以及霍布斯傳統等四大傳統。此外，本文亦將討論上述四項傳統理論的遺緒。吾人以為，當今現實主義學派的主流理論途徑，存在著嚴重的內在邏輯問題，同時這些問題影響著當代的國關研究。主流學者過度關注於特定版本的霍布斯傳統，因而輕視其它於此理論學派中同等重要的途徑之可能性。同時，透過本文對於現實主義理論傳統多元性與豐富性之展現，本文也指出部分擁簇常識現實主義(commonsense Realism)的學者們，事實上已模糊化現實主義的理論本質。針對上述各種內在的理論問題，作者冀望以本文採一種重新詮釋、重新定位現實主義理論根基的途徑來展現並反省。 / Political Realism is suffering from a crisis of superficialization. The profound traditional roots of Political Realism are being simplified or ignored. This thesis attempts to re-examine the classical texts of Political Realism’s traditions and thus raise questions about some problems in this theoretical programme. Four major traditions which are the Thucydidesian, the Augustinian, the Machiavellian, and the Hobbesian tradition will be re-envisioned and re-appreciated, and their legacies to modern Realists will also be expounded. As this thesis would show, serious inherent logical problems exist in the dominant theoretical approach to Political Realism, which has become pertinent to international relations theory study. Mainstream scholars put too much undue attention on a certain version of the Hobbesian tradition and thus overlook other possibilities which are equally important in formatting this vast theoretical school. By showing the richness and diversity of Political Realism’s tradition, this thesis also suggests that the nature of this theoretical programme is being obfuscated by commonsense scholars. All these inherent theoretical problems will be exhibited in this thesis with an approach to re-appreciate and re-envision the traditional roots of Political Realism.
