What is the author's style in The Wretched of the Earth by Frantz Fanon?

The author maintains an almost clinical objectivity as he describes the colonialist system, the resentment of the natives, how that resentment affects their lives as well as the lives of the colonialists, and the various manifestations of human behavior that become inevitable once the rebels decide to take action for their own independence. It is fascinating to observe how this psychiatrist describes the dynamics of personalities and groups of people as the process of change begins. Fanon is adept at pointing out how people's conscious and unconscious motives, their fears and resistance to change, affect behavior.
