Liberum arbitrium[1] est mentis et voluntatis gubernatio, ab omnibus rebus soluta quae agendi licentiae intervenire possint. Quod homines sive actores rationales sinit facere quidquid quocumque loco iudicent optimum factu esse. Quod soli homines hanc potestatem habere videntur, actus liber dicitur actus humanus in philosophia.[2]
Spinoza, qui liberum arbitrium negavit. Pictura a Francisco Wulfhagen anno 1664 facta.
Negatio liberi arbitrii, determinismus appellata, saepe quaestionem moralitatis parit quia facultatem voluntatis humanae de bonis ac malis negare potest.
