“哲学是理论的综合,历史是经验的综合,百科全书是理论与经验的综合。因为她的主旨,在将人类智慧的产业,加以清算,而完毕创导的过程。质言之:她能播送一切创导者的贡献,和许多积累的经验於每一个人,因而成为推进文明的力量,更培植其智慧的自由发展,节省其不要的东翻西检的时间,而使成为再创造之力的源泉。所以百科全书不是一个天才者著书立说的成品,而是一切天才者收获的结果,而又经过大规模之分析与归纳者。我们好象是一个掌管以知识与经验为财产的世仆,当幼主向我们谘问某一财产的情况或提取某一财产的收益为用度时,我们除尽量的敏捷的告诉他之外,而且说明其丰吝和利弊的情形。” ～D. 狄德罗 “Philosophy is a combination of theory, history is a combination of experience, encyclopedia is a combination of theory and experience, because she is the main thrust of the process of creating a human-wise industry, and finishing the process of creation. Broadcasting all the contributions made by the leaders and many accumulated experiences in each and every one so as to promote the power of civilization and foster the free development of their wisdom and save their unnecessary time and make them re-created Therefore, the encyclopedia is not a finished product written by a genius, but the result of all genius harvest, but after a large-scale analysis and inducement we seem to be in charge of a knowledge and experience as the property When the young master asked us about the cost of a property or the cost of withdrawing it, we advised him in addition to his agility as much as possible, and explained his abundance and pros and cons. ”~ D. Diderot
