注：○彼是句：《庄子·齐物论》，“是亦彼也，彼亦是也。彼亦一是非，此亦一是非。”○知，智也。原文云：“莫虚掷汝之韶华，莫为无益之求索，盖彼是之辩殊无谓也。葡萄之累累尽足欢也，岂不佳胜彼无实抑苦实者？”其譬喻译之殊难。黄克孙译曰：“垦道求真终不穫，便成果实亦酸辛。何如独到南山上，摘取葡萄祭酒神。”尚称明快。
Waste not your Hour, nor in the vain pursuit
Of This and That endeavour and dispute;
Better be jocund with the fruitful Grape
Than sadden after none, or bitter, Fruit.
