Reflections on Reading · Second (朱熹·观书有感·其二) by Zhu Xi

Meaning

Last night by the river the spring water rose greatly; that huge war-ship floats, light as a feather. Before, in vain I spent all the force of pushing (yet could not move it); now it can sail freely at ease in the river's midst.

昨天夜里江边春水大涨，那庞大的战船浮起，轻如一根羽毛。从前白白费尽推移的力气（也推不动），如今却能在江心自由自在地航行。

Appreciation

The poem uses boating as a metaphor; throughout it does not state the principle yet the principle shows itself. The first line 'Last night by the river spring water rose' sets the occasion; 'the great war-ship light as a single hair' uses the heavy to figure the light, a startling contrast. The focus is the contrast of 'All along in vain I spent the force of pushing' with 'This day mid-stream it moves at ease' — writing the hardship of 'not yet enlightened' and the joy of 'already enlightened' as if before the eyes. Using water-rise and ship-float for 'when learning is thick, principle connects by itself', the image is bright, principle and interest blend, no pedantic air — most showing Song poetry's strength of 'making the old new, making the common elegant'.

【白话串讲】 “昨夜江边春水生，艨艟巨舰一毛轻”——朱熹写读书的感悟：昨夜江边春水涨了，大船像羽毛一样轻。“向来枉费推移力，此日中流自在行”——以前白费力气推，如今水涨船自走。读书通了，就是水涨了。【意象与手法】诗以泛舟为喻，通篇不说理而理自见。首句「昨夜江边春水生」布设机缘，「艨艟巨舰一毛轻」以重喻轻，反差惊人【情感与主旨】朱熹，婺源人，侨居建阳，南宋理学家、教育家，闽学代表人物，后世尊为「朱子」【名句点睛】中高考常考：①理解「春水」「巨舰」的象征意义，须答出春水喻学力/积累、巨舰喻疑难/大道

Background

Zhu Xi, from Wuyuan, lived by choice in Jianyang, a Southern-Song Confucian scholar and educator, head of the Fujian school, later honoured as 'Master Zhu'. His poems are mostly principle-speaking; the two 'Reflections on Reading' were likely written in the Chunxi years while he lectured at Wuyi and Kao ting, using boating scenery to figure the enlightenment of reading and probing principle. This second piece specially writes the state of learning at the moment 'suddenly it all connects' — through ordinary hard seeking one could not reach, but when accumulation is thick and the trigger touches, then like the spring water full the great ship floats of itself, effortless and attained. It is an image bearing the Confucian tenet of 'accumulate learning to know'.

《观书有感·其二》为南宋朱熹所作，是写读书感悟的七绝。朱熹（1130—1200），字元晦，号晦庵，婺源人，南宋理学家、诗人。此诗：昨夜江边春水生，艨艟巨舰一毛轻。向来枉费推移力，此日中流自在行。全诗以春水生、巨舰行为喻写读书之理，是朱熹诗的名篇。

Art

The poem uses boating as a metaphor; throughout it does not state principle yet principle shows. The first line 'Last night by the river spring water rose' sets the occasion; 'the great war-ship light as a single hair' uses the heavy to figure the light, a startling contrast; the latter two lines 'All along in vain' and 'This day mid-stream' contrast past and present, writing the hardship of 'not yet enlightened' and the joy of 'already enlightened' as if before the eyes. Using water-rise and ship-float for 'when learning is thick, principle connects by itself', the image bright, principle and interest blended, no pedant's air — most showing Song poetry's strength.

《观书有感·其二》艺术上以比喻的贴切与理趣的深婉见长。全诗四句，层层写来：前二句写春水生、巨舰轻——“昨夜江边春水生，艨艟巨舰一毛轻”写春水生、巨舰一毛轻；后二句写枉费推移力、自在行——“向来枉费推移力，此日中流自在行”写枉费推移力、此日中流自在行。全诗以巨舰行为喻写读书之理，正是朱熹诗理趣的笔法。

Allusions

This poem purely uses everyday boating as metaphor, citing no classics, yet its reasoning is rooted in the Great Learning's 'to know lies in investigating things' and the Luoyang Confucians' 'lingering and immersing, suddenly enlightened' method of study. 'War-ship' (mengchong) is an ancient warship name, seen in the Records of the Three Kingdoms; 'mid-stream moves at ease' secretly fits the 'striking the oar mid-stream' image of rousing effort yet reverses its meaning, writing composed delight. The whole writes the utmost principle in common language, not borrowing classical allusion yet self-accordant with the sage's path — exactly Zhu Xi's wonder of 'making principle clear through affairs'.

《观书有感·其二》用典在“艨艟”“一毛轻”。“艨艟”写古代大战船；“一毛轻”用《庄子》“以天下为之笼，则雀无所逃”之意（或“轻于鸿毛”），写巨舰轻如一毛。全诗以巨舰行江为喻写读书之理，用典自然而理趣自见，正是朱熹诗的笔法。

Commentary

This poem with its first ('Whence is the pond so clear? For living source water comes') is called the twin gems of principle-poetry. A Qing critic said 'Zhu Xi's poems have principle-interest yet no principle-obstruction'. The modern Qian Zhongshu, on Song principle-interest poetry, cites this as example, saying 'it does not state principle outright, yet principle is within'. Later ages often use 'spring water floats the ship' for when learning's work arrives, naturally unblocked — far influence.

《观书有感·其二》是朱熹诗的名篇，也是宋代哲理诗的代表作。此诗以春水生、巨舰行为喻写读书之理，向为论者称道。论者多赏其比喻的贴切与理趣的深婉——“昨夜江边春水生，艨艟巨舰一毛轻”写春水生而巨舰轻，比喻贴切；“向来枉费推移力，此日中流自在行”写枉费推移、自在行，更见理趣。朱熹为南宋理学家，其诗以哲理著称，此诗正是其代表——以巨舰行为喻写读书之理，正是其诗风。

昨夜江边春水生，艨艟巨舰一毛轻。

Last night by the river the spring waters rose; the great warship weighed as light as a feather.

昨夜江边春水初生，艨艟巨舰（大船）轻如一毛。

Last night the spring river swelled; the great battleship floated as light as a feather.

前二句写春水生、巨舰轻，是全诗理趣的起点。“昨夜江边春水生”写春水生——“昨夜江边”写昨夜江边，“春水生”写春水初生——昨夜江边春水生；“艨艟巨舰一毛轻”写巨舰一毛轻——“艨艟巨舰”写艨艟大战船，“一毛轻”写轻如一毛——艨艟巨舰一毛轻。二句写春水生、巨舰轻：昨夜江边春水生，艨艟巨舰一毛轻。以“昨夜江边春水生”写春水初生，以“艨艟巨舰一毛轻”写巨舰因水盛而轻如一毛，正是朱熹诗写理趣的起点——水足则舟行，比喻读书之理。

This line writes last night by the river the spring waters rose; the great warship weighed as light as a feather, the spring flood's sudden rise. The word rose writes the flood's swelling, the warship the massive hull, as light as a feather writes the floating's ease. The line writes to the full the feeling of the spring flood lifting the great hull. Rising through the flood, the philosophical quatrain's starting point.

向来枉费推移力，此日中流自在行。

Of old the pushing and hauling were all in vain; this day in midstream it goes freely.

向来枉费推移之力，此日中流自在而行。

Before, all the pushing had been wasted; now, midstream, it sails at ease.

末二句写枉费推移力、自在行，是全诗理趣的归结。“向来枉费推移力”写枉费推移力——“向来”写向来（从前），“枉费推移力”写枉费推移之力——向来枉费推移力；“此日中流自在行”写此日中流自在行——“此日”写此日（如今），“中流自在行”写中流自在而行——此日中流自在行。二句写枉费推移力、自在行：向来枉费推移力，此日中流自在行。以“向来枉费推移力”写水浅时推移之枉费，以“此日中流自在行”写水足时中流自在之行，正是朱熹诗写理趣的归结——学问之理亦然，根基既厚，自然畅行。

The closing line writes before, all the pushing had been wasted; now, midstream, it sails at ease, the landing of the whole's bent. The words of old write the former vain toil, this day the present ease. The line writes to the full the feeling of the wasted pushing and the free sailing. Writing feeling through the sailing, the philosophical quatrain's eye-dotting stroke.
