has persuaded 和 are 谁才是谓语呢？还有，这里的语法成分结构怎么分析呢？

It will force him to place the good of society before his own. It is the very strong link that attaches the individual to the whole. And man, subservient to interests he has persuaded himself are greater than his own, makes himself a slave to his taskmaster.

老师：subservient to interests he has persuaded himself are greater than his own - 这里我不会分析成分和结构，看不懂意思。

尤其是he has persuaded himself are greater，找不到谓语，为什么出现一个himself？ has persuaded 和 are 谁才是谓语呢？还有，这里的语法成分结构怎么分析呢？
