In his plan for a _Déclaration des droits de l'homme et du citoyen_, Lafayette some twelve years later included "_la recherche du bonheur_", in memory of the American Declaration of Independence, but "_la recherche du bonheur_" disappeared in the committee and was never mentioned again in any of the three Declarations of the French Revolution. The nearest approach to it is found in the first article of the Declaration of June 23, 1793; but it simply states that the aim of society is common happiness--and this is quite a different idea. Whether it was right or not, Jefferson, when he reproduced the terms used by George Mason in the Virginia Bill of Rights, gave currency to an expression which was to influence deeply and even to mold American life.
In that sense, it may be said that the Declaration of Independence represents the highest achievement of eighteenth-century philosophy, but of one aspect of that philosophy that could not develop fully in Europe. Trees that are transplanted sometimes thrive better under new skies than in their native habitat and may reach proportions wholly unforeseen.
Thus the Declaration of Independence written to express the sentiments of the day probably shaped the American mind in an unexpected manner. It was essentially a popular document planned to impress the masses, to place before the young nation at its birth a certain ideal and a certain political faith, but it was also a legal and judicial document intended to make more precise the reasons why the united American colonies had finally resolved to separate from the mother country.
For this part of the Declaration Jefferson drew largely from the "Constitution" he had drafted for Virginia and sent to Randolph by Mr. Wythe. He was his own source--the more so as he substantially repeated many of the grievances enumerated two years earlier in the "Rights of British America." But here again he markedly improved the first version, which was a monotonous recital of dry facts, starting with a legal "Whereas" and beginning each article with a clumsy participle. "By denying his Governor permission:... By refusing to pass certain other laws ... By dissolving Legislative Assemblies," became in the Declaration the dramatic presentation of facts by a prosecuting attorney and not the summing-up of a case by a judge. But the final renunciation of the mother country has an unsurpassed dignity, a finality more terrible in its lofty and dispassionate tone than any curse:
