Neither of these is exclusively a political concept. Power is the ability to make significant choices that affect others, whether in private or public spheres. Democracy includes values that affect our feelings and our relationships with other people in all our activities, as well as being a method of public decision-making. The exercise of public choices at that level can affect more people in more radical ways than choices elsewhere. In consequence, the symbols, rituals, and mythic actors at that level affect us all personally and make our cultural lives and institutions a part of politics, not just through laws, but through the formation of our identity itself, through or against these images of power.
Power is good.
The exercise of choice defines our full humanity. Those who are secure in choosing for themselves and others make our history. Absolute weakness is death. Democracy is a means of distributing power, of creating conditions and institutions that empower all. The conditions include study and practice in the exercise of responsible choices.
