未成之卦，易經之終
先看圖像，再讀文字。Read the image before the words.
火在水上，未濟
(The trigram representing) fire over (that representing) water forms Wei Ji.
君子以慎辨物居方。
The superior man, in accordance with this, carefully discriminates among (the qualities of) things, and the (different) positions they (naturally) occupy.
火在水上——方向背道，無法相成，這是未濟之象。君子由此體會：要謹慎地辨別事物，使每樣東西居於適當的位置。
(The trigram representing) fire over (that representing) water forms Wei Ji. The superior man, in accordance with this, carefully discriminates among (the qualities of) things, and the (different) positions they (naturally) occupy.
先讀經文，再讀《彖傳》如何解釋卦辭。The received text, then the Tuan commentary on it.
未濟：亨。小狐汔濟，濡其尾，無攸利。
未濟卦——亨通。但像小狐快渡河時，浸濕了尾巴——還未成事就先損，沒有甚麼利益。
Wei Ji intimates progress and success. (We see) a young fox that has nearly crossed (the stream), but has wet his tail. There will be no advantage in any way.
未濟，亨，柔得中也。小狐汔濟，未出中也。濡其尾，無攸利，不續終也。雖不當位，剛柔應也。
未濟亨通——是因為柔爻（六五）得中位。「小狐汔濟」是說還未走出險中。「濡其尾，無攸利」是說不能持續到底。雖然每爻都不當位，但剛柔之間相應。
Wei Ji intimates progress and success — because of the central position of the weak fifth line. The young fox is still in the midst of the stream. There will be no advantage because there is no continuity. Although the lines are not in their proper places, the strong and weak still respond.
六條線各有一句判斷。閱讀次序初→上；卦象由下而上，看左側的卦。One statement per line, read from the first line to the top. The figure is drawn bottom-up — watch the rail.
濡其尾，吝。
浸濕了尾巴——剛起步就受損，可惜。
The first SIX shows its subject (like a fox) whose tail gets immersed. There will be occasion for regret.
濡其尾，亦不知極也。
浸濕尾巴，是因為不知極限。
曳其輪，貞吉。
拖住車輪不急進——堅守正道則吉。
The second NINE shows its subject dragging back his (carriage-)wheels. With firmness and correctness there will be good fortune.
九二貞吉，中以行正也。
九二之貞吉，是因為居中而能行正道。
未濟，征凶，利涉大川。
事未成——直接前進凶險，但反而利於去涉險渡大河（在險中前進方有出路）。
In the third SIX, with (the state of things) not yet remedied, advancing will lead to evil. But it will be advantageous to (try and) cross the great stream.
未濟征凶，位不當也。
「未濟征凶」，是因為位置不當。
貞吉，悔亡。震用伐鬼方，三年有賞于大國。
堅守正道則吉，悔恨消失——以雷霆之勢征伐鬼方，三年後得到大國的賞賜。
The fourth NINE shows its subject by firm correctness obtaining good fortune, so that all occasion for repentance disappears. Let him stir himself up, as if he were invading the Demon region, where for three years rewards will come to him from the great kingdom.
貞吉悔亡，志行也。
貞吉而悔消，是志向得以實行。
貞吉，無悔。君子之光，有孚，吉。
守正得吉，無悔——君子之光輝煥然，誠信顯現，吉。
The fifth SIX shows its subject by firm correctness obtaining good fortune, and having no occasion for repentance. (We see in him) the brightness of a superior man, and the possession of sincerity. There will be good fortune.
君子之光，其暉吉也。
君子的光輝，是其光明之吉。
有孚于飲酒，無咎。濡其首，有孚失是。
誠信地飲酒（不過量），無咎；但若沉醉到濕了頭，誠信也會失之。
The topmost NINE shows its subject full of confidence and therefore feasting (quietly). There will be no error. (If he) cherish this confidence, till he (is like the fox who) gets his head immersed, it will fail of what is right.
飲酒濡首，亦不知節也。
飲酒到濕了頭，是不知節制。

未濟卦的核心應用：認清「事永遠未完」是常態，不是失敗。九四「震用伐鬼方，三年有賞」告訴我們真正成事的姿態——果斷出擊，但備耐三年。卦序之終以未濟結，提醒讀易者：學易也是未濟，永遠剛開始。
The core application of Wei Ji: recognize 'always unfinished' as the normal state, not failure. Line 4's 'thunderstrike against Gui Fang, three-year reward' shows the right posture — decisive strike, three-year patience. Closing the Yi Jing with Wei Ji reminds the reader: studying the Yi is itself never complete; you're always just beginning.
上九之失：飲酒濡首——本來可以收尾無咎，但慶祝過頭把已得之果毀了。這是一個從古到今最常見的「離成功只差最後一步卻自己跌倒」的模式。
Line 6's failure mode: drinking until even the head is wet — could have ended without error, but overcelebration destroys what was gained. The classic 'one step from success, then trip over yourself' pattern.
王弼以為未濟是 64 卦最特殊的結尾——位皆不當，反而留有變化的空間。既濟之完美已無路可走，未濟之不正反而剛柔相應，亨通可期。彼以為彖傳「雖不當位，剛柔應也」一句最深——位不重要，應才重要。
Wang Bi takes Wei Ji to be the most remarkable ending among the 64 hexagrams: every line out of place — and precisely for that reason, room for change remains. The perfection of Ji Ji has nowhere left to go; the incorrectness of Wei Ji leaves the firm and the yielding still responding to each other, so success can be expected. He holds the deepest sentence of the Tuan to be 'though the positions are not proper, the firm and the yielding respond' — position is not what matters; response is.
程子強調未濟之卦的精神：六五一爻為主——柔得中，居至尊位，雖不當其位但有「君子之光」。讀此卦最該記住的是六五的「君子之光，有孚」——不在於是否完美，而在於是否真誠。
Cheng Yi stresses the spirit of Wei Ji through its ruling line, the fifth: yielding yet central, seated in the place of highest honor — not properly positioned, and yet bearing 'the light of the superior man.' What most deserves remembering is that fifth line, 'the light of the superior man, with sincerity': what counts is not whether one is perfect, but whether one is true.
朱子直言：未濟結束易經，意在揭示「事無終了」之理。卦中六爻皆不當位，象徵世間萬事無有完美；然爻爻皆有應（初與四、二與五、三與上），又象徵不完美中仍有可成。學易至此，知「永遠在路上」即是道之常。
Zhu Xi says plainly: the Yi ends with Wei Ji to reveal the principle that nothing is ever finally finished. All six lines are out of position, symbolizing that nothing in the world is perfect; yet every line has its responding partner (1 with 4, 2 with 5, 3 with 6), symbolizing that within imperfection things can still be accomplished. To study the Yi this far is to know that 'forever on the way' is the constant of the Dao.
易經不收在既濟，收在未濟。六爻全部不當位，事事沒到位，卻爻爻有應，處處還有得做。把這一卦放在全書末尾，等於把話挑明：世上的事沒有做完的一天，「在路上」就是常態。讀完六十四卦，若心裡想的是「我讀完了」，那是既濟的姿態；想著「我才剛開始」，纔站到了未濟給的位置上——易經之終，即學易之始。九四「震用伐鬼方，三年有賞」留給願意在未完成裡繼續走的人：三年的耐性，換得了大賞。
The Yi Jing does not close on Ji Ji, the completed; it closes on Wei Ji, the not-yet. All six lines out of position, nothing quite in place — yet every line has its answering partner, and there is work to do everywhere. Putting this hexagram last says it outright: nothing in the world is ever finished, and 'on the way' is the normal condition. If you finish the sixty-four hexagrams thinking 'I'm done,' that is the posture of Ji Ji; think 'I've only just started,' and you are standing where Wei Ji puts you — the end of the Yi is the beginning of studying it. Line 4, 'he strikes like thunder against the Gui Fang; in three years, reward from the great kingdom,' is left for those willing to keep walking inside the unfinished: three years of patience, traded for the great reward.
Not yet — the 'still to come' that names the hexagram.
To cross over (a river); by extension, to succeed, to complete.
Almost, on the point of — nearly across.
That which; a classical particle equivalent to 所 (suo).
Thunderous movement — to shake, to strike with force.
Radiance, glow — the light of the superior man in line 5.
Sincerity, trustworthiness — inner truth that others can rely on.
易經 64 卦不終於「成」（既濟），而終於「未成」（未濟）——這個排序是古人深思熟慮的選擇。其意在揭示：宇宙與人生從不是線性走向終點的，而是循環往復、永遠未完成。讀完未濟即回到乾坤，這是周易循環觀的終極表達。
The 64 hexagrams do not end at 'completed' (Ji Ji) but at 'not yet completed' (Wei Ji) — an ordering the ancients chose deliberately. Its point: the cosmos and human life never run in a straight line toward a terminus; they cycle, returning again and again, forever unfinished. Finishing Wei Ji sends the reader back to Qian and Kun — the ultimate statement of the Zhou Yi's cyclical view.
未濟與既濟正好相反——既濟六爻皆當位（陰爻居陰位、陽爻居陽位），未濟六爻皆不當位。但易經並不認為「全不當」就是凶；恰恰相反，「不當位」反而留下變化與相應的空間。彖傳「雖不當位，剛柔應也」一句是核心。
Wei Ji is Ji Ji's exact reverse: in Ji Ji all six lines are properly placed (yin in yin positions, yang in yang), in Wei Ji none are. But the Yi does not read 'all improper' as misfortune; on the contrary, improper position leaves room for change and for response. The core sentence is the Tuan's 'though the positions are not proper, the firm and the yielding respond.'
卦辭「小狐汔濟，濡其尾」是一個典型的象徵：年幼經驗不足的狐狸（小狐）幾乎要渡過河（汔濟）卻在最後關頭浸濕了尾巴。古人以此象比喻「成事就差最後一步」的場景，提醒學者「終始如一」的重要。
The Judgment's 'a young fox almost across, wetting its tail' is a classic symbol: a young, inexperienced fox (xiao hu 小狐) has nearly crossed the river (qi ji 汔濟) when it soaks its tail at the very last stretch. The ancients used the image for the scene of 'one step short of done,' reminding the student how much depends on being the same at the end as at the beginning.
九四「震用伐鬼方，三年有賞於大國」與第 63 卦九三「高宗伐鬼方，三年克之」相呼應——同一段商代戰史，從既濟之「克之」（成果）到未濟之「有賞」（持續）。這個對照是周易作者刻意安排的歷史敘事連續性。
Line 4's 'he strikes like thunder against the Gui Fang; in three years, reward from the great kingdom' echoes line 3 of Hexagram 63: 'Gao Zong attacks the Gui Fang; in three years he conquers it.' The same stretch of Shang military history, moving from Ji Ji's 'conquers it' (the result) to Wei Ji's 'reward' (the continuation) — a narrative continuity the authors of the Zhou Yi arranged deliberately.
「未濟」二字的語感是什麼？為何易經以此終卦？
What does Wei Ji feel like? Why end the Yi Jing here?
為何六爻皆不當位卻仍「亨」？
Why is the all-incorrectly-placed hexagram still 'auspicious'?
