Victor's highly conscious sense of the effect of his narrative, from now on, will become a continuing motif (see also, for instance, I:3:13). That he is self-conscious as an artist may be thought a normal attribute of Romantic texts. But Mary Shelley may have a more specific object in mind that that of fitting smoothly into her culture's expectations. Victor's conscious manipulation of his reader (Walton and, beyond Walton, us) continually intrudes on the supposition of its truth.
