Apathy is a word used to often just to describe someone who doesn't agree with how others see things.
History
The word "apathy" derives from the Greek ἀπάθεια (apatheia)[2]. Also meaning "absence of passion", "apathy" or "insensibility" in Greek, the term apatheia was used by the Stoics to signify a (desirable) state of indifference for what one is not responsible for (that is, according to their philosophy, all things exterior, one being only responsible of his representations and judgments). Another way of characterizing the way that the Stoics saw apathy is as "the extinction of the passions by the ascendency of reason".[3]
Many Christians believe that the concept was then reappropriated by Christians, who adopted the term to express a contempt of all earthly concerns, a state of mortification, as the gospel prescribes.[citation needed] The word has been used since then among more devout writers. Clemens Alexandrinus, in particular, brought the term exceedingly in vogue, thinking hereby to draw the philosophers to Christianity, who aspired after such a sublime pitch of virtue.[1] Macaulay referred to "The apathy of despair." Prescott described "A certain apathy or sluggishness in his nature which led him . . . to leave events to take their own course."
The concept of apathy became more well-known after World War I, when it was called "shell shock". Soldiers who lived in the trenches amidst the bombing and machine gun fire, and who saw the battlefields strewn with dead and maimed comrades developed a sense of disconnected numbness and indifference to normal social interaction.
In 1950, US novelist John Dos Passos wrote that "Apathy is one of the characteristic responses of any living organism when it is subjected to stimuli too intense or too complicated to cope with. The cure for apathy is comprehension." US educational philosopher Robert Maynard Hutchins summarized the concerns about political indifference when he claimed that the "death of democracy is not likely to be an assassination from ambush. It will be a slow extinction from apathy, indifference, and undernourishment."
This is why, i feel that the word Apathy is used to often just to describe every individual who does not, Know, or think the same way, although their are obviously those that also just don't care.
