"You can kill a man but you can't kill an idea"

In this quote, civil rights activist Medgar Evers is highlighting the power and durability of concepts. He is recommending that while a person's physical body might be eliminated, their concepts and beliefs can not be destroyed. This is a powerful suggestion that ideas have the ability to transcend time and space, and can continue to influence and influence others long after the individual who initially had them is gone. Evers is also likely mentioning the fact that overbearing forces might try to silence or remove people who challenge their beliefs, however the concepts they stand for will continue to survive on and potentially trigger modification.
