Human beings have struggled since day one to learn the meaning of life. Ideologies arise from human interpretation of the world and belief system, as well as an effort to seek the truth about human nature. Ideologies emerge over periods of great change: the Enlightenment, the “Glorious” English Revolution, the American Revolution, etc. They have become the motivations, norms and roots of modern political systems. Their roots are the philosophies developed by famous philosophers throughout time. However, as each ideology grows, its own contradiction also grows and takes place in the realm of actions. This, in turn, shows the contradiction in human nature. Everything changes over time, and there is no point where things stop changing to a different state, or to something completely different. Heraclitus, a pre-Socratic Greek philosopher, firmly declared: “There is nothing permanent except change. » Heraclitus' works influenced later philosophers and thinkers, notably Georg Wilhelm Friedrich Hegel, a German philosopher of the late 18th and early 19th centuries. To define “contradiction,” I found it understandable to use Hegel’s long-studied principle of non-contradiction. As Horst Althaus says in his Hegel: An Intellectual Biography: "If it is true, as Hegel says, that 'all things are in themselves contradictory,' then the principle of non-contradiction is itself logically contradicted , and the removal of the contradiction as a logical operation becomes in turn a contradiction of the contradicted contradiction or a case of double negation. (Althaus, 131) Thus, for Hegel, the nature of all things is contradiction. For me, that includes human beings. The nature of the middle of the paper unfolds in time, alternating key events and transferring contradictory ideas. The contradiction in the thoughts and actions of revolutionary leaders sometimes makes historical events and their ideologies difficult to determine. It is up to each person to decide whether something is right for them. However, as human nature contains contradictions, the world would continue to change over time. Works Cited Adams, John.
