In "The Idea of Justice," Amartya Sen explores how individuals make decisions when faced with specific proposals or scenarios. He argues that people often rely on their personal conceptions of freedom and justice, and this can influence their willingness to agree to certain proposals. The assumption is that individuals will consider their own definitions of freedom when evaluating proposals.

Sen highlights the complexity of human reasoning in the context of justice, suggesting that it's not enough for proposals to be logically sound; they also need to resonate with people's diverse understandings of freedom. This reflects a broader theme in Sen's work, emphasizing the importance of various perspectives in debates about justice and the challenges of reaching consensus.
