There is land and there is water so then, there is solid and liquid. There is the sky and the realm below it so, there is high and low. Then, there is fire and ice. So, there is hot and cold. Where there are verdant fields there are also barren deserts. Can you think of something without an opposite?
So, now as an integral part of this world, people assume the contradictions in mind and body. Some are tall while some are short. Some are smart while some are stupid. Some are strong and some are weak. Some are beautiful and some are downright ugly (both in body and spirit).

Then again, what if the world were all green? Maybe if we were all born to that world we would accept it as normal. But, as humans wouldn't we have the innate longing for the blues and the browns? And yet, what if all we see were blues and browns? Or reds or yellows? Have we ever wondered why we have the colors of the rainbow? Or why we have the rainbow at all? I think it's obvious. It was just meant to be.

For all humans who find themselves on this world, it is only natural to always look for the alternative. We were made that way. One thought has always another side to it. It is our destiny to look for it and find it.
Are we then doomed to a life of contradiction and conflict? No. Humans think. The human mind knows no boundaries. Where there is contradiction the mind seeks the common ground. And, from there new thoughts arise. For while it is true that for every thesis there is an anti-thesis, it is also true that where there exists a conflict between thesis and anti-thesis there is always a synthesis. In this world of contradictions and opposites that process never ends. If it does, there would be chaos.
