Alfred Lord Tennyson, (1809 - 1892) was Poet Laureate of Great Britain and Ireland during much of Queen Victoria's reign and remains one of the most popular British poets today. Tennyson was known for short lyrics, such as in Break, Break, Break and The Charge of the Light Brigade. A great deal of his property was based on classical mythological themes.
I come from haunts of coot and hern:
I make a sudden sally
And sparkle out among the fern,
To bicker down a valley.
By thirty hills I hurry down,
Or slip between the ridges,
By twenty thorps, a little town,
And half a hundred bridges.
Till last by Philip's farm I flow
To join the brimming river,
For men many come and men may go,
But I go on forever.
I chatter over stony ways,
In little sharps and trebles,
I bubble into eddying bays,
I babble on the pebbles.
With many a curve my banks I fret
By many a field and fallow,
And many a fairy foreland set
With willow-weed and mallow.
I chatter, chatter, as I flow
To join the brimming river;
For men may come and men may go,
But I go on forever.
I wind about, and in and out,
With here a blossom sailing,
And here and there a lusty trout,
And here and there a grayling,
And here and there a foamy flake
Upon me, as I travel
With many a silvery waterbreak
Above the golden gravel,
And draw them all along, and flow
To join the brimming river;
For men may come and men may go,
But I go on forever.
What does the speaker mean by For men may come and men may go, / But I go on forever?
