It is true, that whatever engagements or promises any one has made for himself, he is under the obligation of them, but cannot, by any compact whatsoever, bind his children or posterity: for his son, when a man, being altogether as free as the father, any act of the father can no more give away the liberty of the son, than it can of any body else: he may indeed annex such conditions to the land, he enjoyed as a subject of any commonwealth, as may oblige his son to be of that community, if he will enjoy those possessions which were his father's; because that estate being his father's property, he may dispose, or settle it, as he pleases.
