The essay asserts that tyrants have power because the people give it to them.
By advocating a solution of simply refusing to support the tyrant, he became one of the earliest advocates of civil disobedience and nonviolent resistance. Lew Rockwell summarizes La Boétie’s political philosophy as follows:
To him, the great mystery of politics was obedience to rulers. Why in the world do people agree to be looted and otherwise oppressed by government overlords? It is not just fear, Boetie explains in “The Discourse on Voluntary Servitude,” for our consent is required. And that consent can be non-violently withdrawn.
A conversation between @DavidET and @trawetsdor about simply refusing to buy tickets to attend soccer games as withdrawal of the "consent", made me think of the relevance of La Boetie's essay. Link to the essay by Etienne de la Boetie is attached below.
