“William Blake is an English poet, painter, and printmaker. He lived during revolutionary times and witnessed the downfall of London during Britain’s war with republican France” (Biography). William wrote the poem “The Tyger” during this period (Biography). Based on the historic background, we have the reason to believe that the tiger must have a subtle relationship with the power of revolution. The revolution we mention here is not only the French Revolution, but also the revolution for those who are fighting against the forces of evil and chasing the freedom of world.

What the hand, dare seize the fire?”(Line 7, 8) From the second stanza, Blake depicts a picture of how difficult it is looking for the fire to “make” the eyes of tiger. Here the fire is the fire (symbol) of revolution, what the meaning behind this is that William is trying to say that only if we could get through innumerable trials and hardships can we find the truth of revolution. In the third stanza, William states that “what shoulder, and what art, could twist the sinews of the heart” (Line 9, 10). The “shoulder” and “art” imply the creator of the tiger’s “heart.” Is the creator God? No, it’s not. The creator is the insurgent force. Because of the insurgent force as the creator, then the heart of revolution (tiger’s heart) can grow up. Once it begins to “beat” (11), it will take control of the “dread hand” and “dread feet” (12).
