The ability to say that two plus two make four.
The mathematical equation of 2 + 2 = 4 has been world renowned as the kind of a conspicuous truth since the sixteenth century, and it shows up thus in Johann Wigand's 1562 De Neutralibus et Mediis Libellus: As indicated by the Primary Reflection (1641), the standard of truth is self-proof of clear and unmistakable thoughts. Be that as it may, Descartes addresses the correspondence of these plans to reality
Orwell's hero, Winston Smith, utilizes the expression to think about whether the State may pronounce "two in addition to two equivalents five" as a reality; he contemplates whether, if everyone trusts it, that makes it genuine.
Winston Smith features in the 1984, an incredible novel on an anticommunist. In the story, Winston lives an oppressed and frustrated life under the rule of his bigger brother. He is a rebellion, has fatalistic views and is often victim to panoria. In these circumstances, a person often envisions his freedom. Winston does so in his diary where he describes it as the ability to say that two plus two makes four.
This describes the severity of oppression in his life where he isn’t allowed an opinion in such basic matters that are actually right. Such an environment can scar a human for life and Winston was close to losing his mind.
