You look at the title’s concept, it actually refers to that famous phrase “a government of the people, for the people and by the people.” You don’t have to complicate it. It just simply presupposes listening to and consulting the people that a government is intending to rule or govern. Not an autocratic but a democratic government. Hence you check the origin of the word, the initial part demo is derived from the Greek demos which means people. The second part of the word refers to the kind of activity which is more or less general or common in conceptual meaning.
The meaning is that a democracy takes into consideration the mind or the will of the people, while aristocracy tends to give unlimited power to one person. Present trends are democratic, as the more popular forms, and are also consultative of the people’s opinion.
