“Perchance not he but Nature ailed,
The world and not the infant failed.
It was not ripe yet to sustain
A genius of so fine a strain,
Who gazed upon the sun and moon
As if he came unto his own,
And, pregnant with his grander thought,
Brought the old order into doubt.”
—Ralph Waldo Emerson (1803–1882)

—Penelope Leach (20th century)
“Let us begin to understand the argument.
There is a solution to everything: Science.”
