“Children hit first because aggression is innate, although more dominant in some individuals and less in others, and second, because aggression facilitates desire.  It’s foolish to assume that such behaviour must be learned.  A snake does not have to be taught to strike.  It’s in the nature of the beast.  Two-year-olds, statistically speaking, are the most violent of people.  They kick, hit and bite, and they steal the property of others.  They do so to explore, to express outrage and frustration, and to gratify their impulsive desires.  More importantly, for our purposes, they do so to discover the true limits of permissible behaviour.  How else are they ever going to puzzle out what is acceptable?  Infants are like blind people, searching for a wall.  They have to push forward, and test, to see where the actual boundaries lie (and those are too-seldom where they are said to be).” ~ Jordan Peterson, via 12 Rules for Life (Page 126)
