I can possess by several titles; I can become proprietor by only one--_Non ut ex pluribus causis idem nobis deberi potest, ita ex pluribus causis idem potest nostrum esse_.

The field which I have cleared, which I cultivate, on which I have built my house, which supports myself, my family, and my livestock, I can possess: 1st.

As the original occupant; 2d.

As a laborer; 3d.

By virtue of the social contract which assigns it to me as my share.
But none of these titles confer upon me the right of property.
