The manuscript letter in the Library of Congress is not the one that was used in the different editions of Jefferson's "Works." It is a much corrected and written-over draft, containing several passages which have disappeared in the published text.[38] It contained particularly a request to John Randolph who was going to "the hub of literature", to buy him "books of parliamentary learning." It also included a request to Randolph to sell him his fine violin, to which Randolph acceded, averring that "Tho we may politically differ in sentiments, yet I see no reason, why privately we may not cherish the same esteem for each other which formerly I believe subsisted between us. We both of us seem to be steering opposite courses: the success of either lies in the womb of Time."[39]

Such letters are very significant, for they express better than long dissertations the state of mind of the leading men of the day. The question at issue was still a political question; it was a question of internal politics on which men could differ without necessarily becoming enemies or losing each other's esteem and affection. Less than a year before the Declaration of Independence, independence seemed to Jefferson the worst possible solution, to be delayed and avoided if it were possible.

Chosen again as delegate to Congress, but delayed by the illness and death of his second child, Jefferson reached Philadelphia on September 25, twenty days after the opening of the session. He stayed only until the twenty-eighth of December, and resumed his seat on May 13 of the following year. In the meantime events were moving rapidly. Congress had been advised of the king's refusal even to notice their second petition; and Jefferson, writing a second time to John Randolph, could declare:

Believe me, my dear sir, there is not in the British empire, a man who more cordially loves a union with Great Britain than I do. But by the God that made me, I will cease to exist before I yield to a connection on such terms as the British Parliament propose; and in this I think I speak the sentiment of America. We want neither inducement nor power, to declare and assert a separation. It is will alone which is wanting, and that is growing apace under the fostering hand of our King.[40]

On the sixth of December, a declaration was adopted repudiating allegiance to the king, and the British Constitution was proclaimed "our best inheritance." Four days previously Jefferson had drafted a declaration concerning Ethan Allen, when news arrived of his being arrested and sent to Britain in irons to be punished for pretended treason. For the first time the delegate from Virginia referred to the British as "our enemies" and called upon them to respect "the rights of nations."

At this juncture and shortly after being appointed on an important committee, Jefferson abruptly left Congress and set out for home. The reason for his sudden departure has never been satisfactorily explained. It may have been due to news of the bad health of his mother: she died on March 31, 1776, and this is the only explanation that Randall could offer. It was more probably due to his anxiety about the fate of his family. Communications with Virginia were rare and difficult. He wrote home regularly every week, but on October 31 he had not yet received a word "from any mortal breathing", and on November 7 he repeated:

"I have never received the script of a pen from any mortal in Virginia since I left it, nor been able by any inquiries I could make to hear of my family. I had hoped that when Mrs. Byrd came I could have heard something of them. The suspense under which I am is too terrible to be endured. If anything has happened, for God's sake let me know it!" Two weeks later he urged his wife to keep herself "at a distance from Ld. Dunmore", and he was planning to meet Eppes "as proposed."

There seems to be very little doubt that he yielded to his anxiety and to the entreaties of Eppes who seems to have urged him to come back. He had left at Monticello a sick mother, his sisters, a wife who had recently lost a child and had hardly recovered from the blow, and he was in constant fear that a raid from the British troops, who had already burnt Norfolk, should endanger the lives of his dear ones. Furthermore he believed that his presence in Philadelphia was not indispensable; for he was never one who overrated himself. Finally, a document overlooked by his biographers informs us that on September 26, 1775, he had been appointed by the Committee of Safety for the Colony of Virginia, Lieutenant and Commander in chief of the Militia of the County of Albemarle.[41] In view of Lord Dunmore's impending attacks his presence was evidently required to organize local forces. All these are reasons enough to explain why he left Philadelphia. We do not even know that he hesitated at all or experienced any conflict of duties. National patriotism was still limited by family duty, and local patriotism was stronger in him than obligations to a country which did not yet exist.

So it happened that the man who wrote the Declaration of Independence was to miss many of the preliminary steps and discussions that preceded it. He did not resume his seat in Congress until May 14, 1776. Five days before, a resolution framed by Adams and R. H. Lee had been adopted, instructing the colonies to form governments. It was passed the very day Jefferson arrived in Philadelphia. Not only had he come back rather reluctantly, but he was anxious to return to Virginia in order to participate in the work of the Colonial Convention, as appears from his letter to Thomas Nelson, Junior:
