"Being myself a warm zealot for the attainment & enjoiment by all mankind of as much liberty, as each may exercise without injury to the equal liberty of his fellow citizens, I have lamented that in France the endeavours to obtain this should have been attended with the effusion of so much blood. I was intimate with the leading characters of the year 1789. So I was with those of the Brissotine party who succeeded them: & have always been persuaded that their views were upright."--Thomas Jefferson
The term "Jacobin" was used against Jefferson by his political enemies as a slight. It has been used since in much the same fashion toward others. To Jefferson, the Jacobins were the equivelent of the Democratic Republican Party (aka; Jeffersonians) set though they were, in a very greatly different set of circumstances. Thomas Jefferson explains those circumstances in a letter to James Madison from Paris:
"The property of this country is absolutely concentered in a very few hands, having revenues of from half a million of guineas a year downwards. These employ the flower of the country as servants, some of them having as many as 200 domestics, not labouring. They employ also a great number of manufacturers, and tradesmen, and lastly the class of labouring husbandmen. But after all these comes the most numerous of all the classes, that is, the poor who cannot find work."
He went on to suggest possible solutions...
"I am conscious that an equal division of property is impracticable. But the consequences of this enormous inequality producing so much misery to the bulk of mankind, legislators cannot invent too many devices for subdividing property, only taking care to let their subdivisions go hand in hand with the natural affections of the human mind. The descent of property of every kind therefore to all the children, or to all the brothers and sisters, or other relations in equal degree is a politic measure, and a practicable one. Another means of silently lessening the inequality of property is to exempt all from taxation below a certain point, and to tax the higher portions of property in geometrical progression as they rise. Whenever there is in any country, uncultivated lands and unemployed poor, it is clear that the laws of property have been so far extended as to violate natural right. The earth is given as a common stock for man to labour and live on. If, for the encouragement of industry we allow it to be appropriated, we must take care that other employment be furnished to those excluded from the appropriation."
To Jefferson, it is certain that the laws of property must conform to Natural Law. Where we find descrepancies in his theory of property, it is on account of this.
