Good Faith is a pivotal of socialist core-value system also a principle of civil law and a basis of Chinese traditional culture, so a unificational investigation on Good Faith is very necessary. A crisis of Good Faith is a big obstacle to upgrading and globalizing Chinese economy, so it is very important to reflect thoroughly on the of Good Faith in order that Good Faith Construction can be carried out in a more rational direction based on the investigation of the substantial meaning of Good Faith and the construction route to Good Faith Nation.After Good Faith in Civil Law as code or draft in France, Deutschland and Japan then in China was investigated on historically, a conclusion is brought forth that Good Faith has an original meaning called Bonne Foi in French, Guten Glauben in German and Righteousness in Japanese, but this term is lost in Chinese Civil Law spoiled theoretically or practically. Honest as a term in Chinese culture is systematically investigated on to find its essence was Choosing Goodness and Adhering to It(The Doctrine of the Mean). Based on clarifying substantial and procedural meaning, the paper proposes that the proper direction of Good Faith Construction is The Good Faith Nation, viz. The nation or people essentially honest and principled with Good Faith. Guided with Marxism especially Historic Materialism, the paper discussed five specific construction routes such as Idea Good Faith, State Good Faith, Law Good Faith,Career Good Faith and Ecology Good Faith. |
