Under the influence of both these elements, a quietistic mysticism and an antagonism to reason in matters of faith, his scorn for all natural works grew. This made it easier for him to regard the natural order of human powers as having been completely upset by original sin. More and more he comes to recognise only an appearance of natural virtues; to consider them as the poisonous blossoms of that unconquerable selfishness which lies ever on the watch in the heart of man, and is only to be gradually tamed by the justifying grace of God. The denial of all freedom, under the ban of sin, little by little becomes for him the principal thing, the “_summa causa_,” which, as he says in so many words, he has to defend.[397] Beside the debasement of reason and the false fancies of his mysticism, stood as a worthy companion the religion of the enslaved will; this we find present in his mind from the beginning, and at a later period it obtained a lasting monument in the work “_De servo arbitrio_,” which Luther regarded as the climax of his theology.[398] But there are other connecting-links between Occamism and the errors of the young Monk. According to Occam’s school the purely spiritual attributes of God cannot be logically proved; it does not consider it as proved merely by reason that God is the last and final end of man, and that outside of Him there is no real human happiness, nor even, according to Occam himself, that “any final cause exists on account of which all things happen”;[399] not only, according to him, must we be on our guard against any idea that reason can arrive at God as the origin of happiness and as the end of salvation, but even His attributes we must beware of examining philosophically. God’s outward action knows no law, but is purely arbitrary. Thus Occamism, with its theory of the arbitrary Divine Will, manifesting itself in the act of “acceptation” or imputation, was more likely to produce a servile feeling of dependence on God than any childlike relationship; with this corresponded the feeling of the utter worthlessness of man’s own works in relation to imputation, which, absolutely speaking, might have been other than it is.
