本研究目的在於分析並比較兩種實用主義的道德想像力觀點，首先將討論「深思熟慮宛如想像彩排」之實用主義倫理學比喻，也就是深究J. Dewey「戲劇彩排」，以及由S. Fesmire後續提出「爵士即興」之批判性修正，本研究將此兩種觀點統稱為「即興想像」方法並分別析論其問題。其次則是探究R. Rorty「新實用主義」立場，即主張人們必須具備將整體文化加以「詩化」描述的想望，而不是採取「理性化」或「科學化」的方式來描述它。換句話說，想像力被Rorty「再描述」為「自由反諷」，也就是強調應放棄以理性來取代激情或幻想的企圖，反而應採取平常心來看待每個個別想像得以實現的機會。最後，本研究綜合性評析兩種實用主義的想像力隱喻與問題，期能藉此擴展道德教育方法研究面向及其實踐價值。

This study analyzes and compares two pragmatic viewpoints of “moral imagination.” In the first part, this study discusses the pragmatic metaphor of “deliberation as imaginative rehearsal,” which includes John Dewey’s “dramatic rehearsal” and Steven Fesmire’s critical revision of “improvisational imagination.” In the second part, this study examines Richard Rorty’s neopragmatist standpoint, which emphasizes that culture should be described as a poeticized orientation, not rationalized or scientized. In other words, Rorty redescribes moral imagination as liberal irony. In the last part, this study comprehensively compares the two pragmatic metaphors of moral imagination and extends ethics research and moral instruction methods.
