We infer the watch has a designer, the complicated machinery is designed by somebody... the watchmaker. So much so that the Watchmaker is to watch as God is to universe.
William Paley's teleological argument, the inference is that, as the complicated machinery of a watch proves that it has a designer, the watchmaker, the complexity of the universe proves that it must have been created by God.
Explanation:
He uses this analogy as evidence of God´s existence, and if the watchmaker defines the purpose of his creation, likewise, it is God who defines humans' purpose (telos) in life.
He was a successful leader because he taught his followers to be patient, he never gave up, he motivated his followers, and he led nonviolent protests, and encouraged them.
He thought nonviolence would create change because violence would just make people think badly about them, and it would just make conditions worse.
King thought that some people will still lack rights, and it will take long before those rights are gained.
