Machiavelli is a little known, we keep the adjective "Machiavellian" to refer to efforts to conserve power, largely through manipulation. "The Prince" is indeed a political treaty, which gives good advice in human management. If we put everything into context and avoid application in business, or in the classroom for teachers, the proposed manipulation, analysis of society and human relations remains relevant. A good time for reflection, instructive on humanity as much as over a given period, and a current of thought: humanism.
