From Martin Luther King’s “Where Do We Go From Here” speech

“There is nothing wrong with power if power is used correctly. And one of the great problems of history is that the concepts of love and power have usually been contrasted as opposites – polar opposites – so that love is identified with a resignation of power, and power with a denial of love.

Now power properly understood is nothing but the ability to achieve purpose. It is the strength required to bring about social, political, and economic change.”
