CAP. XLIII. De dubitatione quinta species obligationis.

QUinta species obligationis ponitur Dubitatio. Et est dubitatio, Ob∣ligatio ad sustinendum aliquid tanquam dubium. Unde regulae deservientes huic speciei sunt istae, Ad omne dubitatum in tempore dubitationis propositum respondendum est dubie. Alia regula est, Quod ad contradictorium dubitati respondendum est dubie. Alia regula est, Quod ad consequens falsum respondendum est negando, & ad antecedens verum respondendum est dubie. Alia regula est, Quod ad repugnans non contradictorium nec convertibile respondendum est secundum sui qualitatem. Et similiter ad omne impertinens respondendum est se∣cundum sui qualitatem.
