But his primary task is not to think about the moral code, which governs his activity, any more than a businessman is expected to dedicate his energies to exploration of rules of conduct in business.
【核心词汇】

dedicate to致力于，专注于
【结构分析】
主句的'主干结构是his primary task is not to think about the moral code，非限定性定语从句which governs his activity，修饰the moral code，理解和翻译此句的关键是理解词组not any more than，more than译为“较……多些”，not any more than意为“不比……多些，两者都不”。
【参考译文】
但是，他的首要任务并不是考虑支配自己行动的道德规范，就如同不能指望商人专注于探索行业规范一样。
