Indifference means a real power to act or not, which remains even after the agent has decided
So it is not wrong to place man's freedom in acting in a certain openness and indifference he has toward his acts.
Note, however, that this indifference does not mean, as some seem to suppose, the uncertain state of a man who wavers and has not yet settled which way to turn and lean. It means a real power to act or not act, and to arrange his action one way or another. That power remains even in someone who by his own judgement and choice has settled on these actions or those, and for whom it is fixed and decided to do this and nothing else.
Latin
XXVIII. Itaque libertas hominis in agendo non male constituitur in quadam ejus circa actus suos indeterminatione & indifferentia. Verum observandum est per istam indifferentiam non intelligi, ut quidam suspicari videntur, statum ancipitem hominis fluctuantis, necdum certi quo vergat atque inclinet; sed veram potestatem agendi, vel non agendi, & actionem suam sic, vel sic instituendi; quae manet etiam in eo, qui proprio judicio atque electione se ad actiones has, aut illas determinavit, & apud quem certum & constitutum est hoc & non aliud agere.
