It is a moot question whether the origin of any kind of property is derived from nature at all. It is agreed by those who have seriously considered the subject that no individual has, of natural right, a separate property in an acre of land, for instance. By a universal law, indeed, whatever, whether fixed or movable, belongs to all men equally and in common is the property for the moment of him who occupies it; but when he relinquishes the occupation, the property goes with it. Stable ownership is the gift of social law, and is given late in the progress of society.
Thomas JeffersonReason and free inquiry are the only effectual agents against error... They are the natural enemies of error, and of error only... If [free enquiry] be restrained now, the present corruptions will be protected, and new ones encouraged.
Thomas JeffersonI consider the foundation of the Constitution as laid on this ground that 'all powers not delegated to the United States, by the Constitution, nor prohibited by it to the states, are reserved to the states or to the people.' To take a single step beyond the boundaries thus specially drawn around the powers of Congress, is to take possession of a boundless field of power not longer susceptible of any definition.
Thomas JeffersonThe movements of nature are in a never ending circle. The animal species which has once been put into a train of motion, is still probably moving in that train. For if one link in nature's chain might be lost, another and another might be lost, till this whole system of things should evanish by piece-meal; a conclusion not warranted by the local disappearance of one or two species of animals, and opposed by the thousands and thousands of instances of the renovating power constantly exercised by nature for the reproduction of all her subjects, animal, vegetable, and mineral.
