[IDEM libro quinto ad Sabinum. ] §40.4.2.prSi quis ita heredem instituerit 'Titius heres esto.
[THE SAME, in the fifth book on Sabinus.] If anyone should have appointed an heir in this way: 'Let Titius be heir.
si Titius heres non erit, Stichus heres esto.
If Titius will not be heir, let Stichus be heir.
Stichus liber esto', non esse Stichum liberum Aristo ait Titio herede existente.
Let Stichus be free', Aristo says that Stichus is not free if Titius becomes heir.
mihi uidetur posse dici liberum fore, quasi non utique alio gradu acceperit libertatem, sed dupliciter: quo iure utimur.
It seems to me that it can be said that he will be free, as if he did not receive freedom merely in the other degree, but doubly; which is the rule of law we follow.
