Its not a specific person per say in my interpretation....
Its more of a symbloic persons actions in reaction to events. Picture a group of men sitting around a table with little or no motivation. They are pretty much stuck in their sitautions. The 'one man' parts are how they react.....
Some fight the good fight while others lay over and take it.
When the others ask, "why did you act?" One man will say "in the name of love", "in the name of the father", "in the name of money", "in the name of social class".
It is their justification in the face of hopelessness. It also documents the 'rise" and 'plausibilty' of social change using MLK as an example....
