When I Have Fears
每當我害怕
When I have fears that I may cease to be
Before my pen has gleaned my teeming brain,
Before high piled books, in charactery,
Hold like rich garners the full-ripened grain;
When I behold, upon the night’s starred face,
Huge cloudy symbols of a high romance,
And think that I may never live to trace
Their shadows, with the magic hand of chance;
And when I feel, fair creature of an hour!
That I shall never look upon thee more,
Never have relish in the faery power
Of unreflecting love; —then on the shore
Of the wide world I stand alone, and think
Till Love and Fame to nothingness do sink.
每當我害怕生命或許就要止息，
我的筆來不及苦集盈溢的思緒，
或把文字變為高高堆起的書籍，
像飽貯的谷倉蓄滿成熟的谷米;
每當我看見那綴滿繁星的夜景，
巨大星云畫出非凡的傳奇幻像，
想到即使運氣幫忙，對我垂青，
生前或許也無法追摹這些云影;
每當我感到那瞬間即逝的美顏，
也許從今以后再也不可能看見，
更無法享受輕松愛情魔力若仙
——于是，在廣袤世界的崖岸，
我形孤影單地佇立，細細思量，
直到愛與聲名沉入烏有的穹蒼。
