Much have I seen and known; cities of men

And manners, climates, councils, governments.

Myself not least, but honour'd of them all;

And drunk delight of battle with my peers.

Far on the ringing plains of windy Troy.

​

I am a part of all that I have met;

​

...And this gray spirit yearning in desire

To follow knowledge like a sinking star,

Beyond the utmost bound of human thought...

Most blameless is he, centered in the sphere

Of common duties...

The long day wanes; the slow moon climbs; the deep

Moans round with many voices. Come my friends,

​

'Tis not too late to seek a newer world.

​
