“When he had left the room, I mused over the conversation which had just taken place between us, but I could make nothing out of it, except that it argued an even greater perversity of mental vision than I had been yet prepared for. And this made me wretched; for I cannot bear having much to do with people who think differently from myself.”

Unexpectedly, this turned out to be true.

Context: One cannot be in my position, looked to by some for guidance, without being constantly reminded of the awesomeness of its responsibility. I live with one deep concern: Am I making the right decisions? Sometimes I am uncertain, and I must look to God for guidance. There was one morning I recall, when I was in the Birmingham jail, in solitary, with not even my lawyers permitted to visit, and I was in a nightmare of despair. The very future of our movement hung in the balance, depending upon capricious turns of events over which I could have no control there, incommunicado, in an utterly dark dungeon. This was about ten days after our Birmingham demonstrations began. Over 400 of our followers had gone to jail; some had been bailed out, but we had used up all of our money for bail, and about 300 remained in jail, and I felt personally responsible. It was then that President Kennedy telephoned my wife, Coretta. After that, my jail conditions were relaxed, and the following Sunday afternoon -- it was Easter Sunday -- two S. C. L. C. attorneys were permitted to visit me. The next day, word came to me from New York that Harry Belafonte had raised $50,000 that was available immediately for bail bonds, and if more was needed, he would raise that. I cannot express what I felt, but I knew at that moment that God's presence had never left me, that He had been with me there in solitary.

Context: There is a limitation, in other words, upon the power of the United States to bring about solutions. I think our people get awfully impatient and maybe fatigued and tired, and saying "We have been carrying this burden for 17 years; can we lay it down?" We can't lay it down, and I don't see how we are going to lay it down in this century. So that I would say that the problems are more difficult than I had imagined them to be. The responsibilities placed on the United States are greater than I imagined them to be, and there are greater limitations upon our ability to bring about a favorable result than I had imagined them to be. And I think that is probably true of anyone who becomes President, because there is such a difference between those who advise or speak or legislate, and between the man who must select from the various alternatives proposed and say that this shall be the policy of the United States. It is much easier to make the speeches than it is to finally make the judgments, because unfortunately your advisers are frequently divided. If you take the wrong course, and on occasion I have, the President bears the burden of the responsibility quite rightly. The advisers may move on to new advice.
