Imagine you knew nothing about your physical and mental attributes, your social status, and your material possessions. All the characteristics that distinguish you from other people would be hidden. From this perspective, what would a just society look like in today's world? In his most famous work, A theory of justice, the American philosopher John Rawls uses this thought experiment to illustrate his theory of justice. In a state of perfect equality, free and rational people agree on a social contract on the principles of coexistence. This social contract is made behind a 'veil of ignorance' in which no one knows their position in society, their class, or their status. Privileges such as money, power, intelligence, personality, moral standards, etc. are supposed to be completely hidden behind the veil of ignorance. This is a purely theoretical construct designed to prevent people from being disadvantaged by chance. In this state of complete equality, no one would be able to propose laws that would favour them as individuals. Rawls sees this original state behind the veil of ignorance as the necessary starting point for establishing principles of justice.
