盧梭的思想內涵豐富，不同學者由於關切的焦點不同，其所研究的主題也各異，例如，有些學者關懷的是盧梭思想在觀念史上的定位與影響，另外有些學者則是關心盧梭思想中的民主或極權成分，但是關於盧梭思想中公民共和主義的要素，則少有人提及。因此，本文的主要論旨即是從公民共和主義的核心觀念──腐化與德行此一角度切入，分析其政治思想。 根據此一研究主軸，本文第二章探討的是盧梭思想中的腐化意涵、腐化的歷程，以及造成腐化的各種因素，並將腐化的現象區分成政治腐化與和財產相關的社會腐化。面對這些腐化現象，盧梭是以德行作為對治之道，一方面以德行為標準批判當時政治、社會的腐化，另一方面則是以德行作為理想政治共同體重建的基礎。盧梭的這些想法似乎是深受古典共和主義思想家，以及古斯巴達與羅馬兩共和國影響。關於盧梭德行觀將在本文第三章探討。 以德行為基礎的政治共同體重建，將可在盧梭的社會契約理論，以及盧梭為其他國家草擬憲法、改革政制的著作中獲得印證。社會契約接櫫了理想政治共同體的原型，而社會契約的締結與維繫則有賴一位卓然出眾的立法家，他一方面轉化、消除造成腐化的種種因素，另一方面則創造培育德行的環境，使「德行共和國」的理想得以實現。 然而並非所有思想家對腐化的思考方向都和盧梭相同，孟德斯鳩與康士坦都提出和盧梭相異的思考，本文最後將探討這些思想家和盧梭思想的差異之處。 / The essence of Rousseau‘s thought is rich. A wide variety of focuses are thus occurred due to various scholar’s different concerns. Their research subjects are different too. For example, some scholars concern the position and influence of Rousseau’s thought on the idea of history, while others concern the components of democracy and authoritarianism of his thought. Nevertheless, the concerning of the elements of Rousseau’s thought on civic republicanism is not very prevailing. The main purpose of this thesis is from the core concept of civic republicanism, i.e., corruption and virtue, to analyze Rousseau’s political thought. Based on this research core, the second chapter of this thesis discusses the meaning of corruption, its process and the factors in causing corruption, as well as to divide the phenomena of corruption into political corruption and social corruption which is relevant to property. Rousseau dealt these corrupt phenomena with virtue. One the one hand, he applied virtue as the standard to criticize the contemporary political and social corruption. On the other hand, he applied virtue as the foundation to reconstruct ideal political community. The thought of Rousseau seems to be influenced by the classical republicanism thinkers and the two ancient Republic, i. e., Sparta and Rome Republic. Rousseau’s view toward virtue will be discussed in the third chapter of this thesis. The foundation of reconstructing political community by virtue will be found in Rousseau’s theory of social contract and to be proved in Rousseau’s drafting the manuscript of constitution reform policy for other states. Social contract reveals the stereotype of ideal political community, however, the binding and the maintaining of social contract depends on an outstanding legislator. On the one hand, he transforms and eliminates the various factors of corruption formation. On the other hand, he creates the various environment of virtue cultivation, enforcing the “Republic of virtue” to be realized. Not every thinker’s way of thinking toward corruption is the same with Rousseau. Montesquieu’s and Constant’s thinking are different from Rousseau. The last part of this thesis will discuss the differences among them.
