I loved with a mixture of affection and reverence that knew no bounds
This reticence is exactly what friendship is intended to transcend, if we take Walton's notion of its value as a benchmark. He looks to an ideal friend "to regulate [his] mind" (I:L2:2). Even Victor, in the revised text, conceives the value of a friend as being "to perfectionate our weak and faulty natures" (I:L4:23). Victor's reserve, however, negates this function of friendship, suggesting a limit to how far it is able to surmount the barriers of what a later time might call ego-defences.
