Everyone has a responsibility to the society of which he is a part and through this to mankind.
参考译文：每个人都对他所属的社会负有责任，并且通过对社会负责任，而对人类负有责任。
备注(1)：of which he is a part为关系代词which引导定语从句修饰前面名词“society”，关系代词which指代前面名词“society” 结构为he is part of the society=他属于社会一部分。
备注(2)：this指代前面的 a responsibility to the society。
备注(3):to mankind前省去了everyone has a responsibility 。
