正向心理學試圖扭轉傳統心理學的疾病模式，協助人追求幸福/ 快樂與美好生活。這不僅與當代品格教育的哲學奠基者 Aristotle 關心的主題幸福相同，Seligman 甚至有意為備受爭議的「德福一 體說」背書。本文旨在探討根據Seligman 的幸福/ 快樂理論，品格長 處與德行在促成個體幸福/ 快樂中扮演的角色。研究發現，Seligman 的幸福/ 快樂概念包含三個層次/ 層面，亦即愉悅的、美好的、有意 義的生活，而真實的快樂位於後兩者；完整意義的幸福/ 快樂則應兼 容三者。Seligman 提出的核心論點真實的快樂有賴施展個人長處 與德行，依此德行與幸福/ 快樂是一體、密不可分的。這對教育的啟 示是，要想使學生獲得真實的快樂，過美好與有意義的生活，則有賴 慧眼辨識並積極培養學生長處與德行，使之投身正向活動。此論點有 助於更詳實闡明「教育幸福」的概念，並與十二年國教「適性揚才」 的教育理念若合符節。

Positive psychology attempts to reverse the disease model upon which psychology had traditionally advanced, and to help the general people live a happy life. This very concern of interest is shared with the main philosophical founder of contemporary character education, i.e. Aristotle, whose primary concern is eudaimonia/ happiness. Seligman aims to endorse the age-old controversial doctrine of the unity of virtue and happiness. This paper aims to elucidate the role which character strengths and virtues play in promoting an individual’s happiness in the light of Seligman’s theory of happiness. It is found that Seligman’s concept of happiness is comprised of the pleasant life, the good life, and the meaningful life, and happiness in the full sense is composed of the aforementioned three kinds of life. Among them, authentic happiness is derived from the latter two kinds of life. Seligman puts forth a central thesis to the effect that authentic happiness comes from exercising one’s signature strengths and virtues, and it is in this sense that virtue and happiness are said to be unified. An important educational implication is that in order to help the student to obtain authentic happiness and lead a good and meaningful life, an educator has to identify and nurtureeach student’s signature strengths with insight, and to engage him/her in positive activities with strengths and virtues. This thesis helps to illustrate the concept of “education well-being” and it is also allied with the ideal of “adaptive education” in the twelve-year basic education programme.
