Thomas Jefferson's Three Propositions

In order to support his principle, Jefferson gives examples of three particular propositions. First, Jefferson mentions property, specifically landed property. Every generation had the right to make a living on earth. If one during his time “[eats] up the usufruct of the lands” or keeps it from the future generations, then the lands would not belong to the living, it would be considered that it belongs to the dead. Second, Jefferson notes public debts. One generation should not be burdened with the debts of another generation. He questions would it not be sensible for France to add in its new constitution that no debt could be contracted beyond the term of nineteen years? Absolutely, Jefferson thought, such a plan would save the people from
unjust taxes and “bridle the spirit of war” by reducing the power to borrow within natural limits. Third, and most important, Jefferson applied the principle to the constitution and laws of government. “The earth belongs always to the living generation. . . They are masters too of their own persons, and consequently may govern them as they please. Every constitution then, and every law, naturally expires at the end of 19 years. If it be enforced longer, it is an act of force, and not of right.” In his letter, Jefferson repeats multiple times that the Earth belongs to the living generation.
