The philosopher Georg Wilhelm Friedrich Hegel (1770-1831), a German idealist from the early modern period, expanded upon the work of Immanuel Kant and many others to develop his own school of thought, known as Hegelianism. Over time Hegel developed his own concept of utopia (see Utopianism), or peace on earth, and how he thought that it could or would be achieved.
How to Achieve Hegel’s Vision of Utopia on Earth
According to Hegel:
Humanity incrementally progresses towards pure reason, freedom, rationality, self-fulfillment, and world peace.
Freedom is choosing to be a rational person
A rational person is a person who purposely chooses to conform to or believe in pure reason.
Pure reason is making a conscious decision to choose to believe that all opposing viewpoints can converge to become synonymous, to choose to believe that all truth is relative (see relativism), or to choose to conform to a single viewpoint (see Groupthink) in an effort to create world peace and a utopian society. (see Collectivism)
In other words, good can mean bad and bad can mean good, what is good or bad is entirely relative to an individual or society, or that everyone will choose to agree on a single definition of what good is and a single definition of what bad is.
A person will feel fulfilled because he/she is making these choices for the greater good.
World peace will come when all people purposely choose to conform to the opinion that all opposing thoughts can have the same meaning, choose to conform to the opinion that all truth is relative, or to choose to conform to a single viewpoint. They will feel fulfilled because they will make the choice to conform for the greater good of society. As there will no longer be any disagreement or conflict in society humanity can create world peace
