Abstract:Historical confidence, a specific political discourse and category, is the CPC's attitude and practical consciousness based on its deep understanding and memory of the“four histories(party history, new China history, reform and opening up history, socialist development history)and their laws, especially the process and experience of the great rejuvenation of the Chinese nation. The establishment logic of historical confidence needs to be explored from the perspectives of the combination of Marxism and the historical spirit of the Chinese nation, the historical achievements of the Communist Party of China in the past century, the beginning of a new journey to achieve the second centennial goal in the new era, and the lessons learned from the nihilistic history of some socialist countries. The three perspectives respectively constitute the cultural foundation, social foundation, realistic needs and practical consciousness of a firm historical self-confidence. The cognitive structure of historical -confidence is composed of three levels. Firstly, keeping the “four histories” alive is the basic requirement to enhance historical confidence. Secondly, pursuing the historical mission of national rejuvenation is the key to boosting historical confidence. Thirdly, it is the purpose of enhancing historical confidence is to know history, love the party, and love the country, which is the basis of historical identity. These three levels show a progressive logical relationship. As a basic confidence, historical confidence is an important practical guideline for fostering the “four confidences (confidence in the path, theory, system, and culture of socialism with Chinese characteristics)” so as to build a sure spiritual foundation for the Chinese communists.
