today we'd use social media to quickly spread a controversial idea, but in the eighteenth century, the printed pamphlet was highly effective. and thomas paine took full advantage of it. on january 9, 1776, when paine published his pamphlet, "common sense," he wanted to push the american people toward independence from britain. it ultimately ignite the american revolution. thomas paine argued that the monarchy was evil and should be rejected as a form of government. to underscore his point, he cited the bible to argue his case -- in judges 8: 22-23: "the israelites said to gideon, 'rule over us, you and your son and your ' gideon told them, 'i will not rule over you. the lord will rule over you'" (nrsv).

in ray bradbury's short story "a sound of thunder", mr. eckels's fearfulness leads to drastic consequences for the rest of the world.

in the story, mr. eckels, who is a hunter, hires a time travel company to travel to the age of dinosaurs. although he is excited for the hunting expedition at the beginning, when they reach there and mr. eckels sees the tyrannosaurus, he feels frightened. as he is afraid of the tyrannosaurus, he steps off the path although he has been warned not to do it. by stepping off the path, the entire course of the future is affected: mr. eckart alters the future by stepping on a butterfly, which causes a new man to be elected president in the future. in that way, it is mr. eckart's fearfulness what triggers 'the butterfly effect' and what leads to drastic consequences for the rest of the world.
