With time things wither away. We lose our youth, our friends, and our things. As with life, liberty has grown old, and is at risk of being forgotten and tossed aside.
Thus, is the reality of the cycles of time. In history we can see that systems of liberty always begin with courage and virtue, only to wither away under the assault of tyrants and complacency. The Roman Republic became an empire, and the Saxons gave way to King George and the Fabians.
Tyranny is not something people wish for, nor do they desire it. Tyranny creeps in incrementally, guided by a mask of progress, encouraged by hopes of change. Darkness is behind the tyranny, but it never originally reveals its true form. Darkness would never be accepted if we knew it was darkness, so it reveals itself as an angel of light, a wonderful thing that is for the common good and the good of the community.
