Pacifism refers to a specific set of beliefs and it includes the principle that any violence at all is wrong even if violence is used against the individual. There are pacifism quotes that include some of the biggest changes in society that were achieved using peaceful means rather than using violence. Someone who practices pacifism is called a pacifist, and when confronted they refer to resort to violence no matter what happens. Even if self defense is justified it is not used by someone who believes in pacifism, because they prefer to use peace so that others follow the same example. A pacifist refuses to fight in wars or to engage in battle in any way because violence is evil no matter what reason it may be used for.
