名人诗歌|Motto to the Songs of Innocence and of Experience

The Good are attracted by men's perceptions，

And think not for themselves；

Till Experience teaches them to catch

And to cage the fairies and elves.

And then the Knave^{1 begins to snarl2，}

And the Hypocrite to howl；

And all his good friends show their private ends，

And the eagle is known from the owl^3.
