There are three primary forces in reality that make it impossible for a perfect government, a perfect ideology, a perfect church, a perfect company, or a perfect person to exist. They are these: uncertainty, complexity, and entropy (decay). Ideas are, in their base form, perfect, but only in the form of an idea. Even bad ideas are perfect in the sense that conceptually they should work if applied. (This is not necessarily a moral perfection, but a perfection of the ideal outcome of the idea, although moral perfections apply as well) Once an idea is applied in a system of matter and energy of relative complexity, the complexity leads to a degree of uncertainty that is impossible to anticipate or significantly control, and that once perfect concept cannot maintain its perfection in a physical world, and becomes flawed and unpredictable. Entropy, or decay, plays an important factor in this as well. Since m...
