so vicious and base
The Creature's education in and through the simultaneity of contraries (see II:3:6 and note) leads him to a large political and social realm that is difficult for him to assess. He is hardly the first to have such a reaction. This sentence resonates with the same sense of frustration with the contradictions of the human condition expressed by Byron's Manfred (Manfred was begun in the summer of 1816) in a similar Alpine setting to that in which the Creature speaks.
How beautiful is all this visible world!
How glorious in its action and itself;
But we, who name ourselves its sovereigns, we,
Half deity, half dust, alike unfit
To sink or soar, with our mix'd essence make
A conflict of its elements, and breathe
The breath of degradation and of pride,
Contending with low wants and lofty will
Till our mortality predominates,
And men are—what they name not to themselves,
And trust not to each other.
