Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Hate destroys a man's sense of values and his objectivity. It … - Martin Luther King Jr.

There are two kinds of laws: man's and God's. A man-made code that squares with the moral law, or the law of God, is a just law. But a man-made code that is inharmonious with the moral law is an unjust law. And an unjust law, as St. Augustine said, is no law at all. Thus a law that is unjust is morally null and void, and must be defied until it is legally null and void as well. Let us not forget, in the memories of 6,000,000 who died, that everything Adolf Hitler did in Germany was 'legal', and that everything the Freedom Fighters in Hungary did was 'illegal.'

All this is simply to say that all life is interrelated. We are caught in an inescapable network of mutuality; tied in a single garment of destiny. Whatever affects one directly, affects all indirectly. As long as there is poverty in this world, no man can be totally rich even if he has a billion dollars. As long as diseases are rampant and millions of people cannot expect to live more than twenty or thirty years, no man can be totally healthy, even if he just got a clean bill of health from the finest clinic in America. Strangely enough, I can never be what I ought to be until you are what you ought to be. You can never be what you ought to be until I am what I ought to be.

In a sense we've come to our nation's capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. This note was a promise that all men, yes black men as well as white men, would be guaranteed the inalienable rights of life, liberty, and the pursuit of happiness. It is obvious today that America has defaulted on this promissory note insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check, a check which has come back marked "insufficient funds." But we refuse to believe that the bank of justice is bankrupt. We refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation. And so, we've come to cash this check, a check that will give us upon demand the riches of freedom and the security of justice.
