“Turn thy thoughts now to the consideration of thy life, thy life as a child, as a youth, thy manhood, thy old age, for in these also every change was a death. Is this anything to fear?”
IX, 21

The Columbiad (1807)
Context: Here then, said Hesper, with a blissful smile,
Behold the fruits of thy long years of toil.
To yon bright borders of Atlantic day
Thy swelling pinions led the trackless way,
And taught mankind such useful deeds to dare,
To trace new seas and happy nations rear;
Till by fraternal hands their sails unfurl'd
Have waved at last in union o'er the world. Then let thy steadfast soul no more complain
Of dangers braved and griefs endured in vain,
Of courts insidious, envy's poison'd stings,
The loss of empire and the frown of kings;
While these broad views thy better thoughts compose
To spurn the malice of insulting foes;
And all the joys descending ages gain,
Repay thy labors and remove thy pain.

The Kasîdah of Hâjî Abdû El-Yezdî (1870)
Context: There is no Heav'en, there is no Hell; these be the dreams of baby minds,
Tools of the wily Fetisheer, to 'fright the fools his cunning blinds.
Learn from the mighty Spi'rits of old to set thy foot on Heav'en and Hell;
In Life to find thy hell and heav'en as thou abuse or use it well.

Wieland; or, the Transformation (1798)

“It is thy very energy of thought
Which keeps thee from thy God.”
