Visibility.

It's ironic how Mr. Pontellier is always acting to be seen by society, he doesn't want to be an outcast and how on the other opposite, the character in Invisible Man is declaring himself invisible. It is clear that Pontellier hides most of his reality to fit into society, he camouflages Edna's decisions, for example when she moved out and he said they were remodeling the house, or when she wouldn't go to the wedding and he went only to excuse her. In Invisible Man, the character doesn't care about society, he lives his way and even commits crimes. He is stealing constant energy supply from Monopolated Light and Power saying, "it allows me to feel my vital aliveness". The reason why he does it, is to teach the company a lesson. While he was trying to fit in society, this light company took lots of his money so now he does this as revenge. The character in Invisible Man tries to teach society a lesson. He takes matters into his hands, for example that night he got into a fight with a man on the street. Trying to get some respect, the character tries to make the blonde man apologize, with no result, he starts kicking him, thinking that there has to be some kind of respect. Then it just came to his mind that it is possible that the man hadn't actually seen him, just as he was about to kill him. Perfect timing.

At the beginning of the book, there seem to be a lot of similes and metaphors. The invisible man compares himself several times to different things. He uses a simile to say he is invisible "like the bodiless heads you see sometimes in the circus sideshows", most times these heads aren't seen because they are ignored by the crowd just like everyone ignores him. He then uses a metaphor to question whether he actually exists or if he is only a phantom in the mind of others. He not only compares his invisibility but he also compares his actions to those of visible man. After having kicked the man, he compares his actions with the actions of a drunken man. It's ironic that he compares himself to a drunken man, because humans under the influence of alcohol seem to be everything but invisible. They are loud and they are constantly moving around, disturbing others. The reason he compares his actions to this man is that drunk men usually don't think their actions through, so when he attacks the man he bumped into, he feels thoughtless.
