"The main force used in the evolving world of humanity has hitherto been applied in the form of war"

Arthur Keith, a popular Scottish anthropologist and anatomist, makes a poignant observation about the historic role of war in shaping human societies. In specifying that the "primary force used in the developing world of mankind has actually hitherto been applied in the type of war", he recommends that conflict has been a main driver for development, change, and development throughout human history.

It is crucial to understand that Keith's statement isn't a glorification of war, but rather an acknowledgment of its undeniable impact. Wars have traditionally shifted political limits, modified societal structures, and even spurred technological and cultural developments. For example, ancient empires such as Rome expanded their territories mainly through conquest, spreading their culture, language, and innovations across large regions. Likewise, the two World Wars of the 20th century accelerated technological advancements and social modifications at an unprecedented speed, reshaping global politics and resulting in the facility of worldwide bodies like the United Nations.

Keith's observation also looks into the duality of human nature. While wars frequently emerge from mankind's baser instincts-- ambition, fear, and the mission for dominance-- they also highlight durability, showcasing humankind's capacity for innovation, restoration, and adjustment. The social shifts that follow conflict typically cause brand-new ideologies and reformations in governance and social norms, indicating that war, while destructive, can paradoxically add to social advancement.

However, it's essential to contextualize Keith's assertion in contemporary terms, where the emphasis has actually slowly moved towards diplomacy, financial collaborations, and international cooperation as ways of solving conflicts. The evolution of human society recommends a potential move far from war as a driving force, advocating rather for peace and partnership as pathways to progress. Hence, while Keith encapsulates a historical reality, the contemporary world progressively looks for to use alternative approaches of promoting human advancement.
