答案

Public duty may not necessarily mean details of offical duty主句
although it may include that constant and active practical participation in the details of politics without which,upon the part of the most intelligent citizens,the conduct of public affairs falls under the control of selfish and ignorant or crafty and venal men让步状语从句,其中it may include 是主谓
that constant and active practical participation in the details of politics 是宾语从句,作include的宾语
without which,upon the part of the most intelligent citizens,the conduct of public affairs falls under the control of selfish and ignorant or crafty and venal men是定语从句修饰先行词participation
这个without which...定语从句中upon the part of the most intelligent citizens是对象状语；the conduct of public affairs 是主语；falls under the control of selfish and ignorant or crafty and venal men是系表结构作谓语.
