Nearly since the dawn of time, humanity has believed it faced struggles of greater difficulty and complexity than the world had ever experienced. While this is undoubtedly true, a side effect of science and technology and all that they bear, societal struggles have always been variations on a single theme: the Haves versus the Have Nots. And whether the Have Nots want money, food, freedom, or even just respect, there's one thing the Haves always have that they hate to give up, and that is power. Power relieves that which is the most common, least desired, and most underrecognized aspect of humanity--fear. And though fear simply serves to help lower thoughtful beings survive, for man it's been so much more, as man's most productive work has come in finding new ways to twist and turn it to his advantage, and to conceal it wherever necessary. What will the future bring? You may not recognize it at first, but everything you saw yesterday, will be everything you see tomorrow, sprinkled with a touch of new understanding, and a touch of new complexity.
The comforting thing about the universe is that it expands linearly, whereas the human mind expands and contracts with enough regularity to leave us dumbfounded by the lack of answers we have to all our most important questions.
