Power. Another one of those loaded words.
Power is a fundamental aspect of human ecology. It is extremely hard to describe though and its importance to survival over time is quite variable. I suspect that humans are just too new and civilization and civil organization to be able to understand the real implications of power. Realize, even the American Constitution which is considered one of the most advanced political documents in existence, will probably look very primitive and uninformed after what is a very short period of time in terms of survival. Certainly many things basic to it will continue to be considered basic in the future, but human knowledge of political governing systems, that is organizational systems, is likely to vastly improve over time.
It has been said that power is the power to kill. I would be more inclined to look at it as the power to build. Realistically though, in human terms the power to build is the power to compete. Ultimately, competition is about survival. Power may be the power to kill, but it is more important here in terms of it offering the power to survive.
Power is also associated with organization, because it is organization that has always created power in human societies. If there is an organization in a society, it defines that there is power.
Human civil society has always had power concentrated in small groups, whether military or religious authorities. Social and political development has created systems where the power is disbursed more. These systems, such as various forms of democracy, seem to work quite well. What they lose in simplicity of organization, they seem to more than make up for in the self-interest of the common individuals who have been empowered. The success of all political systems though is based upon organization and cooperation. Power tends to be nullified by lack of cooperation or organization.
There is nothing that says an advanced society must be democratic. It is just always turned out that there are very few examples of a benevolent despotcies and they always suffer with the problem of the transferal of power.
In any case, with the assumption that an advanced society can only be created based upon a great deal of cooperation and looking at the success of ' free' systems, it seems reasonable to assume the future human ecology's will include extensive distribution of power. A corollary of this and the idea that power simply does exist in any organized society, is that an individual should consciously exercise their power or else the power will not remain distributed. Humans are political animal. Any person who is not exercising the political power, is leaving the power wasted or else used by someone else. An important aspect of survival, that is an important aspect of morality, is that the individual should husband of their individual power.
