“If a law is unjust, a man is not only right to disobey it, he is obligated to do so” is a popular saying that has been printed on many images. The saying is often credited to American statesman, diplomat, lawyer, architect, philosopher and third president Thomas Jefferson (1743-1826), but he never said it.
   
“One has not only a legal, but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws” was written by Dr. Martin Luther King, Jr. (1929-1968), “Letter from a Birimingham Jail,” on April 16, 1963. “‘We believe it is a Christian duty to disobey unjust laws,’ Charles V. Willie, a Harvard professor and vice president of the church’s lay-clergy House of Deputies, told the congregation” was printed in the Delaware County (PA) Daily Times on July 30, 1974.
     
“If a law is unjust, a man is not only right to disobey it, he is obligated to do so. Thomas Jefferson” was posted on the newsgroup soc.culture.malaysia on November 20, 1999.
     
“If a meme is dank, a man is not only right to steal it, he is obligated to do so.-Thomas Jefferson” is a jocular variation on the saying.

Comments: This quotation has not been found in Thomas Jefferson’s papers.  It has been suggested that it is a paraphrase of Jefferson’s statement in the Declaration of Independence, “...whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government…,” although such a paraphrase would seem to be taking some radical liberties with the original version.  The quotation bears a much closer resemblance to Martin Luther King, Jr.‘s comment in his famous letter from Birmingham Jail: “One has not only a legal but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws.”

One may well ask: “How can you advocate breaking some laws and obeying others?” The answer lies in the fact that there are two types of laws: just and unjust. I would be the first to advocate obeying just laws. One has not only a legal, but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws. I would agree with St. Augustine that “an unjust law is no law at all.”

Appearing on NBC’s “Today” show, King said a man expressed “the highest respect for law” if he breaks a law his conscience says is unjust and willingly accepts the penalty.
