A new species would bless me as its creator and source; many happy and excellent natures would owe their being to me. No father could claim the gratitude of his child so completely as I should deserve theirs.

‘I know that while you are pleased with yourself, you will think of us with affection, and we shall hear regularly from you. You must pardon me if I regard any interruption in your correspondence as a proof that your other duties are equally neglected.’

With these words from Chapter 4 in which Victor quotes an admonishment from his father, the theme of The Harmful Effects of Isolation and Alienation is again evoked, but this time with the suggestion that these feelings are rooted in self-hatred.
