词源etymology
塞万提斯 1605／1615 年的小说主人公 Don Quixote（堂吉诃德）→ quixotic。 1718 年英语里首见这个形容词——一个虚构人物走出小说， 在词典里领到了自己的词条。骑士没打赢风车，赢了英语。

背景the story
它与 grok 同属一个小传统：小说造的词，词典收了编—— 学者造词转正（petrichor、numinous、eucatastrophe、penumbra、limerence）之外的文学支线。
词义里住着一杆天平：三百年来，quixotic 一头是嘲（不切实际）， 一头是敬（明知不可为）。用的人落在哪一头，暴露的是自己对理想主义的汇率。
It belongs with grok to a small tradition: words coined in novels, hired by dictionaries — the literary branch beside the scholars’-coinage line (petrichor, numinous, eucatastrophe, penumbra, limerence).
A balance lives inside the meaning: for three centuries quixotic has held mockery (impractical) in one pan and respect (undaunted) in the other. Where a speaker’s usage settles reveals their personal exchange rate on idealism.

《论语》里有现成的一句，还是别人评孔子的：「知其不可而为之」。 同一种人，两种打分——quixotic 贬里带笑，晨门那句敬里带叹。 「堂吉诃德式」如今也是中文熟语，但那是借条； 「明知山有虎，偏向虎山行」是武侠版，多了勇、少了那份天真的错位。
The Analects holds the ready sentence — said of Confucius by a gatekeeper: 知其不可而为之, “he is the one who knows it cannot be done and does it anyway.” One kind of person, two gradebooks: quixotic mocks with a smile; the gatekeeper reveres with a sigh. 堂吉诃德式 is now current Chinese too, but that is a loan slip; 明知山有虎，偏向虎山行 is the wuxia edition — more courage, less of the naive misreading of windmills.
The one-man newsletter against the algorithm was quixotic and, for exactly that reason, worth subscribing to. 自拟例句 our own example, not a quotation Restoring the wetland with hand tools was quixotic arithmetic — and the herons voted for it anyway. 自拟例句 our own example, not a quotation 词典词（MW／OED），正式写作可用。 用前想清楚自己站哪头： 它可以是温柔的嘲，也可以是克制的敬——句子的其余部分要替你表态。
A dictionary word (MW/OED), safe in formal prose. Decide your pan of the balance before using it: it can be a gentle mock or a reserved salute — the rest of your sentence must cast the vote.
