Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.

Though wise men at their end know dark is right,
Because their words had forked no lightning they
Do not go gentle into that good night.

Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.

Wild men who caught and sang the sun in flight,
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.

Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.

And you, my father, there on the sad height,
Curse, bless, me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.

Four Seasons fill the measure of the year;
There are four seasons in the mind of man:
He has his lusty Spring, when fancy clear Takes in all beauty with an easy span: He has his Summer, when luxuriously Spring’s honeyed cud of youthful thought he loves To ruminate, and by such dreaming high Is nearest unto Heaven: quiet coves His soul has in its Autumn, when his wings He furleth close; contented so to look On mists in idleness—to let fair things Pass by unheeded as a threshold brook:— He has his Winter too of pale misfeature, Or else he would forego his mortal nature.

The poetry of earth is never dead:
  When all the birds are faint with the hot sun,
  And hide in cooling trees, a voice will run
From hedge to hedge about the new-mown mead;
That is the Grasshopper's—he takes the lead
  In summer luxury,—he has never done
  With his delights; for when tired out with fun
He rests at ease beneath some pleasant weed.
The poetry of earth is ceasing never:
  On a lone winter evening, when the frost
    Has wrought a silence, from the stove there shrills
The Cricket's song, in warmth increasing ever,
  And seems to one in drowsiness half lost,
    The Grasshopper's among some grassy hills.

When I have fears that I may cease to be 
  Before my pen has glean’d my teeming brain, 
Before high piled books, in charact’ry, 
  Hold like rich garners the full-ripen’d grain; 
When I behold, upon the night’s starr’d 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.
