These are people who have undergone a serious change in political philosophy. Usually, it takes some extreme experiences to change somebody's mind after they are 25 years old - either being burned by friends, or being mugged, arrested, or disillusioned by hypocricy. Sometimes, a thinker simply reflects and undergoes a change of consciousness. These are individuals who have either gained fame or lost fame due to changes in their political positions.
