When from our better selves we have too long
Been parted by the hurrying world, and droop,
Sick of its business, of its pleasures tired,
How gracious, how benign, is Solitude.
~ William Wordsworth, The Prelude IV 354
What can we gain by sailing to the moon if we are not able to cross the abyss that separates us from ourselves? This is the most important of all voyages of discovery, and without it all the rest are not only useless but disastrous.
