Productive work is the central purpose of a rational man's life, the central value that integrates and determines the hierarchy of all his other values. Reason is the source, the precondition of his productive work - pride is the result.
富有成效的工作是理性人生活的核心目标，是整合并决定他所有其他价值层次的核心价值。理性是源泉，骄傲是结果，是他工作富有成效的前提。
