1. Neither Way or Conclusion is Proved Necessarily

72. To the question it can be said that the Philosopher fails to prove his conclusion necessarily and the theologians fail as well, not to say failing to do so by necessary reason, but even failing to do so by evident authority of Scripture.

73. And it is plain from what has been said how what is adduced for the second way [sc. that of the theologians] is solved. But the reasons for the Philosopher’s way will be solved later [nn.97-102].

74. What then? The first part [sc. that of the Philosopher] seems to be proved more than the second; although the second part [sc. that of the theologians] is not got expressly from Scripture, it does seem to agree more with the words of the saints and of Scripture.

So the possibility of each part can be proved.
