Throughout history there have been a variety of theories of human nature proposed by intellectuals of different time periods. A general idea of ​​human nature is defined as the set of characteristics, emotions, and behavioral traits shared by all human beings. During each philosopher's different time periods, human nature varied due to his involvement in politics. Political theories and morals derive from historical imprints and observations. The precise ways to govern or govern a constitution have been questioned and emphasized by many philosophers and theorists. It is history that points to what a long-term, mandated government may need to thrive. To understand a specific theory for a specific period, you need to look at the author's history and society. For example, Machiavelli, Aristotle, and Frederick Douglass each come from different time periods where the structure of society differs. Societies reflect the morals and ideals related to its generation and highlight the structure and nature of people. Therefore, when looking closely at political theories, one must first look at the society and history of the author. A particular theory can influence many governments and political organizations, whether by its validity or its rejection, both of which play a role in structuring a society. Human nature within each society also played a role in the desire for justice. For example, during the era of Jim Crow laws there was a clash between the beliefs of those who opposed discrimination and segregation and those who supported the laws in society. Overall, human nature plays a key role in the political theories of different time periods. Niccolò Machiavelli, Italian politician and philosopher, is a very important influencer... . For example, it highlights how slavery is a direct violation of the values ​​and claims established in the United States Declaration of Independence. Douglass states, “What, to the American slave, is your Fourth of July? I answer: a day that reveals to him, more than all the other days of the year, the gross and cruel injustice of which he is a constant victim” (Douglass). More importantly, Douglass points out that people within society try to use their moral judgment more efficiently to see how slavery is wrong. In Douglass' situation, he talks about how freedom and happiness are unpromised and equally available to every individual in society. During Douglass' time, African Americans were not given the opportunity to experience human nature. However, in the cases of Machiavelli and Aristotle, both individuals were able to experience human nature in society.
