Partible

If souls be not unible, nor partible substances, there is no place for this doubt: if they be, they will be still what they are, notwithstanding any such union with a common soul.

Following the introduction of partible inheritance in 1793, peasants reacted by using systematic birth control for the first time so as to restrict the number of heirs among whom their property would have to be divided – causing a sharp and enduring drop in France's birth-rate.
