Human beings have struggled since day one to learn the meaning of life. Ideologies arise as a human interpretation of the world and belief system, as well as an attempt to seek the truth of human nature. Ideologies emerge during periods of great change: the Enlightenment, the English “Glorious” Revolution, the American Revolution, etc. They have become the motivations, standards and roots of modern political systems. Their roots are the philosophies developed by famous philosophers throughout the ages. However, as each ideology develops, so does its own contradiction, which takes place in the realm of actions. This, in turn, shows the contradiction of human nature. Everything changes over time and there is no moment when things stop changing into a different state or a completely different thing. Heraclitus, a pre-Socratic Greek philosopher, firmly states: “There is nothing permanent except change.” Heraclitus' works influenced later philosophers and thinkers, including 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 principle of non-contradiction, which has been studied at length. 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 suppression of contradiction how a logical operation in turn becomes a contradiction of the contradicted contradiction or a case of double negation”. (Althaus, 131) Therefore, for Hegel, the nature of everything is contradiction. This, to me, includes humans. The nature of the... center of the card ...... unfolds over time, alternates key events and transfers contradictory ideas. The contradiction in the thoughts and actions of revolutionary leaders sometimes makes it difficult to determine historical events and their ideologies. It is up to each person to decide if something is right for them. However, since human nature includes contradictions, the world would continue to change over time. Works Cited Adams, John.
