You see them? You see the things that float and flop about you and through you ever moment of your life? You see the creatures that form what men call the pure air and the blue sky? Have I not succeeded in breaking down the barrier; have I not shown you worlds that no other living men have seen?
Tragedy is an imitation not only of a complete action, but of events inspiring fear and pity. Such an effect is best produced when the events come on us by surprise; and the effect is heightened when, at the same time, they follow as cause and effect. The tragic wonder will then be great than if they happened of themselves or by accident; for even coincidences are most striking when they have an air of design.
Whenever you take a step forward, you are bound to disturb something. You disturb the air as you go forward, you disturb the dust, the ground. You trample upon things. When a whole society moves forward, this trampling is on a much bigger scale; and each thing that you disturb, each vested interest which you want to remove, stands as an obstacle.
