理性是人的一种基本认知能力。客观世界的复杂性以及人本身能力的有限性等客观原因决定了理性的有限性。理性的有限性给多元价值存在的公共生活实现一致行动带来了诸多不便。公共理性对于弱化个体理性价值取向的内在倾向,调适理性的有限性具有一定的作用,有利于增进公共利益,促进社会发展。 Reason is a basic human cognitive ability. The objective reasons, such as the complexity of the objective world and the limited ability of human beings, determine the limitation of rationality. The limitation of rationality has brought a lot of inconvenience to the concerted action of public life with multiple values. Public reason has a certain role in weakening the inherent tendency of the individual’s rational value orientation and in adapting the limited nature of rationality, which is beneficial to promoting the public interest and promoting social development.
