Pity would be no more
 If we did not make somebody Poor;
 And Mercy no more could be
 If all were as happy as we.
 And mutual fear brings peace,
 Till the selfish loves increase:
 Then Cruelty knits a snare,
 And spreads his baits with care.
 He sits down with holy fears,
 And waters the ground with tears;
 Then Humility takes its root
 Underneath his foot.
 Soon spreads the dismal shade
 Of Mystery over his head;
 And the Catterpillar and Fly
 Feed on the Mystery.
 And it bears the fruit of Deceit,
 Ruddy and sweet to eat;
 And the Raven his nest has made
 In its thickest shade.
 The Gods of the earth and sea
 Sought thro' Nature to find this Tree;
 But their search was all in vain:
 There grows one in the Human Brain.
