布莱克老虎。诗人仰望造物主创造的老虎，惊叹其烈火般的形貌与力量，更追问创造者何以既造温顺羔羊又造猛虎。诗中短促有力的问答，蕴含对善恶同源的敬畏与思索，是《经验之歌》的压卷之作。
Tyger Tyger, burning bright,
In the forests of the night;
What immortal hand or eye,
Could frame thy fearful symmetry?
In what distant deeps or skies
Burnt the fire of thine eyes?
On what wings dare he aspire?
What the hand, dare sieze the fire?
And what shoulder, & what art,
Could twist the sinews of thy heart?
And when thy heart began to beat,
What dread hand? & what dread feet?
What the hammer? what the chain,
In what furnace was thy brain?
What the anvil? what dread grasp,
Dare its deadly terrors clasp?
When the stars threw down their spears
And water’d heaven with their tears:
Did he smile his work to see?
Did he who made the Lamb make thee?
Tyger Tyger burning bright,
In the forests of the night:
What immortal hand or eye,
Dare frame thy fearful symmetry?
