Over time we have always managed to find a way to disagree and we have skillfully developed new methods of violence to escalate these disagreements. The fist became a stick and the stick became a stone, the stone became a bow, then a sword, then a gun. We grew our campaign of destruction from local to global, gassing and nuking ourselves to an all time low. During our endeavors a continent was pillaged and its inhabitants enslaved, 6 million people were murdered for being circumcised, we got more creative and introduced temperature to determine the type of war being fought, two towers fell and so did two countries, oh and a celebrity lost her dog ... (Just a quick brush on the topics that made the headlines)
Lets face facts, much of what we uphold to be the centerpiece of the human civilization is nothing more than a hypocritical assault on logic. The premise that humans are in someway smarter and less barbaric than other animals is somewhat flawed in my opinion. We are probably the only animals on planet earth that have sat down and intricately authored our own destruction ... We made our peace with death and came to realize that life was a much more formidable foe.
