Editing Aggression (section)

==Etymology==
The term aggression comes from the [[Latin]] word ''aggressio'', meaning attack. The Latin was itself a joining of ''ad''- and ''gradi''-, which meant "step at". The first known use dates back to 1611, in the sense of an unprovoked attack.<ref>[http://www.merriam-webster.com/dictionary/aggression Merriam-Webster: Aggression] Retrieved 10 January 2012</ref>

A psychological sense of "hostile or destructive behavior" dates back to a 1912 English translation of [[Sigmund Freud]]'s writing.<ref>[http://www.etymonline.com/index.php?term=aggression Online Etymology Dictionary: Aggression] Retrieved 10 January 2012</ref> [[Alfred Adler]] theorized about an "aggressive drive" in 1908.
