本計畫試圖從柏拉圖靈魂三分說裡「慾望」對整個靈魂認知活動的影響，回應他 知識理論中對「知覺」的定位，以重新爱清柏拉圖美學中「知覺」與「慾望」這兩個 和身體緊密相關的概念。研究範圍以《理想國》、《法律》、《泰鄂提得斯》、《菲得若絲》 涉及靈魂三分說、文藝教育、以及「知覺」認知意涵的相關段落，做為核心文本，試 圖處理以下議題：一、《理想國》中如何區分靈魂不同成分，有著這些成分的靈魂又如 何能是一個完整整體？ 二、《法律》中如何理解靈魂内的不同成分？三、從靈魂三分說 的脈絡看《理想國》與《法律》中的文藝教育。四、由《泰鄂提得斯》對「知覺」是 否是知識的討論，以及《理想國》對「信念」與「知識」的區分，返回審視「慾望」 以「知覺」所構成的認知。五、「知覺」與「慾望」在人朝向「美」的認知活動中，扮 演什麼角色？ 同時，本計畫也藉由參與整合計畫「中西美學中的『美感知覺』研究」，一方面接 受其他美學領域研究者的刺激，重新審視柏拉圖美學中這兩項和身體緊密相連的概 念，另一方面藉由對柏拉圖這兩項概念的探討，為其它美學研究者提供有關「美感知 覺」的西方古希臘美學視域。
The project is to explore Plato‟s concepts of perception () and appetitive desire (). Both the concepts are deeply involved with „body‟ which is considered with little importance in traditional or stereotyped „Plato‟. However, this research project will turn attention to the rich discussions on appetitive desire and perception in Plato, especially in the passages on the tripartite soul, art education and the cognitive significance of perception, in the Republic, Laws, Theaetetus, and Phaedrus, and thus attempt to provide a re-examination on Plato‟s aesthetics in the light of these two body-involved concepts. The research will be led by the controversial issues on the doctrine of the tripartite soul into an investigation on Plato‟s treatment of appetitive desire in his psychology and of perception as a kind of cognitive resource. It will mainly tackle the following themes: 1. How does Plato conceive the partition of the soul in the Republic? Does he conceive the elements within the soul as agent-like? 2. How does Plato conceive the partition of the soul in the Laws? 3. Review Plato‟s acceptance or rejection of art education in the Republic and Laws within the context of his tripartite soul. 4. Review Plato‟s „perception‟ as the cognitive resource for „appetitive desire‟, in the light of the epistemological discussion on perception in the Theaetetus and the distinction between belief () and knowledge () in the Republic. 5. Review the significance of perception and appetitive desire in the cognitive process toward the beauty itself. The project is subordinate to the research project „Studies on “Aesthetic Perception” in Chinese and Western Aesthetics‟. By the team work which provides opportunities for co-workers to share aesthetic views with each other, the project is to refresh our understanding of these two body-involved concepts in Plato‟s aesthetics and in connection with other studies in aesthetics as well.
