When I have fears that I may cease to be Before my pen has gleaned my teeming brain, Before high-pilèd 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. Which of the following best describes a theme of the poem?
A. Lost love
B. Fear of the unknown
C. Never achieving one’s desires
D. Brevity of life
