Does history progress? Yes and No.
History is not like it was during the Barbarian Invasions, or is it?
History is like it has always has been and ever will be when we look at the need for balancing power. Power corrupts and absolute power corrupts absolutely. Tyranny is the name for living under such absolute power.
We cannot survive without vision about our country's future. How and what can we do to make our country "better"? How will we progress into the future? Can we find a way forward through the "culture wars"?
How do we maintain civility when most everyone has lost a sense of direction, OR their sense of direction seems to be challenged? How are we to act as "a people" to one another? Do we believe and upholde the ultimate value of our nation, liberty?
Progress has been experienced in our country through scienctific discoveries, technological advances, and through social changes, that brought about a greater hope to all. Law is not just to maintain order, or control over others, but to bring about a culture that seeks to do justly. And the basis of our laws, is that we are all equal under law, this is what justice is.
Equal under law does not mean that we all have equal abilities, interests, or motivations. But, it does mean that whoever has a desire and will "to be" or "to do" will be given an opportunity. Our society should be invested in the human and the humane, as this is what our Declaration of Independence was/is about, natural rights.
Does history progress? It is up to you, as an individual, to see that it does, and that can only be done with the will to serve and be self-reflective.
