de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

At age 15, on March 2, 1955 in Montgomery, Claudette Colvin refused to give up her bus seat to a white woman. This was nine months before Rosa Parks took the same action. Colvin was motivated by her lessons on African American history and the U.S. Constitution. Parks knew Colvin from the NAACP Youth Council and was inspired in part to take her action by Colvin.
