Martin Luther King's carefully crafted speech using pathos, repetition, and metaphors emphasizes his deeply rooted love and dedication to unalienable human rights. A rhetoric device commonly used by King in is 'I Have a Dream' speech was repetition. His use of repetition assist him in generating his points. An example of this would be his constant use of "One hundred years later." King uses this to stress to the listener's how long of a stretch that it has been and the right thing still has yet to be done. This helps the listener to understand where King is coming from and relate to it.
