Morals are arbitrary rules of conduct voted into existence by the popular majority of any given society. Oftentimes, they are deployed by a single dictator or monarch. Morals are a human construction that varies by Time, Geography and Circumstance.
All of the morals we value today will someday become "outdated" or deemed "barbaric" by a future society that no longer feels the same way. Therefore, morals are rules generated by the consensus of like-minded individuals. It evolves over time as the structure of the social network evolves.
It does not "improve" or "degrade" over time - it simply changes based upon the shifting desires of a given social system. Morals do not exist in some aether of matter nor does it exist in the stars or the trees. It also does not exist when a human being is alone.
It only emerges when humans form a group. Thus, morals are not imbedded within us. It is entirely a social phenomenon.
Today, most of those wildly different social spheres have largely dissappeared - replaced by a more or less globalized moral system whose societies are now wholly interconnected through vast trade agreements and international resolutions through the United Nations Security Council and the General Assembly. We humans self-consider ourselves to be morally justified to kill animals whether it be for food, resources or sport. Morality does not apply to other animals - it only applies to us.
Should then, an advanced alien from the stars be morally justified to come here and use us for food, resources and sport? This demonstrates that morality is a relative, synthetic concept, solely for the convenience of man, rather than a universal and absolute dictum that can be arrived at by rational thought. What kind of morals would you have if you were born some 2500 years ago, into the legendary tribes of the Mayans?
Would you have the morals of 21st century America which were fought over centuries of hardships and a civil war? Would you have christian morals even though christianity wasn't even invented yet? No.
You would be a Mayan and believe wholeheartedly in the Mayan ways of life - even if that life was to sacrifice children to the great gods of the stars. And there would be no competing society to tell you otherwise for many thousands of years - all the way up to the 16th century when Spanish and Portugese exploration ships arrive. Child sacrifice would simply be another tradition in your own way of life that you have been taught in your own unique microcosm.
Would you have been born in the wrong place at the wrong time?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
