The first element emphasized by the writer in these passages is that politics is based on a basic reality, which is human pluralism, given that pluralism is the law of the land, or also that there is nothing that does not exist in the individual, as I explained in the first part of the life of the mind: thinking. So, living for the benefit of man means that living is between soil and equals within the city-state, considering that leaving the group and public space is tantamount to isolation and death, and thus the futility of politics for the conduct of public affairs. The world is formed only by humans and what humans produce from the land and nature, and with the existence of a relationship between all these elements and the human group that is required to be organized to avoid wars, violence, and perhaps annihilation envisaged by totalitarian regimes. Politics is the field in which people coexist, i.e. the public arena of the Greeks, the Senate of the Romans, parliaments and the various institutions generated by the current democratic regimes.
