余自錢塘移守膠西②,釋舟楫之安,而服車馬之勞;去雕墻之美,而蔽采椽之居③;背湖山之觀,而適桑麻之野。始至之日,歲比不登④,盜賊滿野,獄訟充斥;而齋廚索然,日食杞菊。人固疑余之不樂也。處之期年,而貌加豐,發(fā)之白者,日以反黑。予既樂其風俗之淳,而其吏民亦安予之拙也。于是治其園圃,潔其庭宇……為茍全⑤之計。而園之北,因城以為臺者舊矣,稍葺而新之。

世上種種到頭來都會成為過去。心力衰竭時,我安慰自己,這一切都會過去;當我因成功洋洋得意時,我提醒自己,這一切都會過去:窮困潦倒時,我告訴自己,這一切都會過去;腰纏萬貫時,我也告訴自己,這一切都會過去。是的,昔日修筑金字塔的人早已作古,埋在冰冷的石頭下面,而金字塔有朝一日,也會埋在沙土下面。如果世上種種終必成空,我又為何對今天的得失斤斤計較?
孔子認為教育是“興于詩”“立于禮”“成于樂”,其中就包含著對美育的重視。今天,我們用“中國夢”來激勵人心,一定意義上說就是全民族的“興于詩”;加強制度建設(shè)、強調(diào)制度自信,一定意義上說也就是新時代的“立于禮”;“成于樂”的“樂”不僅是音樂之“樂”,快樂之“樂”,而且是在道德的普遍高尚,活力的競相迸發(fā),精神的昂揚向上,人民對美好生活的追求中不斷實現(xiàn)的“天下盡歡顏”之“樂”。從古至今,先賢們對于美育的思考從未止步,這些思想結(jié)晶在今天仍具有現(xiàn)實意義,社會主義文化大發(fā)展大繁榮來自民間、來自大變革的時代,我們正在大踏步邁向現(xiàn)代化,尤其需要加強美育。

嗟夫!予嘗求古仁人之心,或異二者之為,何哉?不以物喜,不以己悲,居廟堂之高則憂其民,處江湖之遠則憂其君。是進亦憂,退亦憂。然則何時而樂耶?其必曰“先天下之憂而憂,后天下之樂而樂”乎!噫!微斯人,吾誰與歸?
