Martin Luther King on the proper basis of power

Power...is the ability to achieve purpose. It is the strength required to bring about social, political or economic changes. In this sense power is not only desirable but necessary in order to implement the demands of love and justice. One of the greatest problems of history is that the concepts of love and power are usually contrasted as polar opposites. Love is identified with a resignation of power and power with a denial of love... What is needed is a realisation that power without love is reckless and abusive and that love without power is sentimental and anaemic. Power at its best is love implementing the demands of justice. Justice at its best is love correcting everything that stands against love.
