 The subjective circumstances of justice also include limitations on human knowledge, thought, and judgment, as well as emotional influences and great diversity of experiences. These lead to biases and inevitable disagreements in factual and other judgments, as well as to differences in religious, philosophical, and moral convictions. In Political Liberalism, Rawls highlights these subjective circumstances, calling them “the burdens of judgment” (PL 54–58). They imply, significantly, that regardless how impartial and altruistic people are, they still will disagree in their factual judgments and in religious, philosophical and moral doctrines. Disagreements in these matters are inevitable even among rational and reasonable people. This is “the fact of reasonable pluralism” (PL 36), which is another general fact known to the parties in the original position. Reasonable pluralism of doctrines lends significant support to Rawls’s arguments for the first principle of justice, especially to equal basic liberties of conscience, expression, and association.
