Weep not that the world changes—did it keep A stable, changeless state, 'twere cause indeed to weep. - William Cullen Bryant

Here the free spirit of mankind, at length,
Throws its last fetters off; and who shall place
A limit to the giant's unchained strength,
Or curb his swiftness in the forward race!

To him who in the love of Nature holds
Communion with her visible forms, she speaks
A various language.

Thine eyes are springs in whose serene
And silent waters heaven is seen;
Their lashes are the herbs that look
On their young figures in the brook.
