"social contract" in constant evolution --- I would only partly agree with this statement.

In democracies, the dialogue must be broader and include not only security and human rights communities but all of civil society. Moral values and ethics are constantly evolving and reflect the changes in a society. The balance between security and freedom of expression is a "social contract" that must be agreed upon by the majority of citizens of a country or group of countries.

In autocracies, the State fixes the terms of the "social contract" and tries to have it accepted by the population by any necessary means.
