In as few words as possible, Guy Montag from Bradbury's Fahrenheit 451 is:
Shy, awkward with people, discontented, unhappy, unsatisfied, inquisitive, curious, brave, and open to new ideas.
Discontented means he is not content with his life. He is unsatisfied in the sense that he knows there must be something more to life and existence than he has. Inquisitive is similar to curious but perhaps a little stronger. And he wants to learn and be exposed to new ideas.
Montag has many personality traits, but I hope what I've listed above helps you out.
Guy Montag is a fireman who is the main character of the book. In this book, firemen do not put out fires. Instead, they burn down the houses of people who are caught in posession of books.
At the beginning of the book, Montag is satisfied with his life and his work. But then a variety of things happen and he starts to doubt the goodness of burning books and he starts to wonder if his society might need to be changed completely.
Because of this, he starts to read books. This leads to his house getting burned down. He then kills his boss and runs away to the countryside, hoping to have a chance to help change society later on.
Montag is a common, working class man who initially never questions society or the complexities of life. He lives a robotic existence in a society that places little to no value on individuality. Through Clarisse, a teenage girl who questions the small nuisances of life, Montag’s internal conflict is incited. Montag begins to question the world. This puts him in conflict with his employer, his wife, his neighbors, and, for the most part, society. Montag eventually decides the conflicts he faces are worth battling. He sacrifices his “comfortable” life as a firefighter to live as a fugitive, then amongst an underground circuit of rejects that have devoted themselves to continuing the individual thought that literacy offers.
Montag is the thirty-year old firemen who realizes his life is empty and oppressive. He searches for meaning in books and from others like him. He is unsatisfied with the society and is basically the main character who trys to go against the society.
