The fact is that the lessons of history are there to be learned but weather mankind will listen to what they have to say is another matter entirely. It is said that "Those how do not learn form their mistakes are doomed to repeat them" and yet here we are repeating the same mistakes our forebears did.
The names, places, dates and so forth change throughout history but by and large the root causes remain the same, in the last 6,000 years there have been many significant advances made, the change form hunter/ gathering to settled farming and the formation of the first communities, moving for stone tools to bronze and much latter iron.
Other significant achievements are the formation of the first City States with the first organizational structures, the invention of the first laws, as well as writing, mathematics, agriculture, philosophy and astronomy and yes the invention of the first monetary systems.
Change is difficult to accept for many people for example you can fight a war like say the 100 years war (1337 to 1453 AD) that people know there is a war to fight but can not remember why it started in the first place and history is replete with other examples but time moves on and change must be made, for the equation is vary simple Adapt or Die.
