Every code ever devised has proven ephemeral, swirling and drifting through the fashions of time, irrespective of the heavy hand of governance. The true liberal recognizes this, and remains nimble enough to adjust, adapt, and advance. The conservative tends to be held in check by the random rockslide of theism, having to back-test new ideas against an artificial status quo with the usual anticlimactic results. Absolutes have historically been hypocritically implemented (and eventually exposed), bargained with, modified, and outright abandoned. Why? Because the sovereign evolution of humankind is always looking for a better deal (be it personal or societal), and will side-step any barrier to achieve it. Intellectual flux will be the legacy left by this species.
