an anarchist school of thought often called "Anarcho Individualism", "Anarcho Egoism" but usually just shortened to "Egoism"
The idea was originally proposed by the
German philosopher Max Stirner in his
book "The Ego and Its own" or also known as "The
Unique and its Property"
it says ideas like The State,
Religion, God(s), Laws, Capitalism, Morality, The Market and Societal Obligation are "spooks" or ideas that suppress the individual sense of self (aka the "ego") while not actually being real just illusions created by our masters to suppress us (aka "ghost of the mind" as Stirner would put it)
One of its main idea is that the ego (your sense of self) should strive to do things that make you
happy and give you fulfillment rather than being restricted by society
It is just "Do whatever you want I don't care"
