Kant argues in the brief but extremely important essay, <em>What is Enlightenment?, </em>that society, before the age of Enlightenment, which Kant precisely defines in this essay, has behaved like a minor in as much as a child cannot think for himself but rather is given the guidelines for his behavior. Kant then claims that it is time for society, and everyone in it, to become an adult and dare think for one´s self, imposing the guidelines for thought and action based on one´s own transcendental discovery of the limits of thought, what can be thought, and what that, in practical terms, entails for every individual´s freedom. This moment in society could not have been reached without the achievements gained through the Enlightenment that provide the necessary and qualified freedom that society as a whole lacked before it.
King was a minister criticized by clergymen, so he tried to justify his cause by paraphrasing the words of Thomas Aquinas, a notable interpreter of God's order on earth.

King provides a religious justification for the concept of nonviolent resistance.
