Explore the theme of isolation in Mary Shelley's Frankenstein.

Isolation is one of the most important themes of Frankenstein. Walton isolates himself from all companionship when he embarks upon his expedition to the frozen wastes of the north. Victor Frankenstein is also isolated, both emotionally and intellectually. He's separated from the ordinary run of humanity by his scientific genius; there's really no one who can understand what's going on in that over-worked super-brain of his.
He deliberately chooses to further isolate himself from his fellow man by the experiments he conducts. Frankenstein is even isolated from his fellow scientists by his creation of the Monster. And this condition looks set to continue indefinitely, for the brave new world he envisages involves his being all alone at the top. He wants to create a race of beings who will worship him like a god. And being treated like a god is guaranteed to keep you apart from the rest of humanity.
Frankenstein passes on his sense of isolation to the Monster he creates. But the Monster doesn't want to be alone; he wants Victor to make him a brand new mate. When Frankenstein develops moral qualms over the issue, the Monster threatens to make life hard for his creator. Eventually, Victor relents and takes off to the remote Orkney Islands to create the second creature. Once again, he understands the necessity of isolation; such a diabolical experiment must be conducted well away from prying eyes.
It's notable that when the Monster first confronts Victor, it's against the splendidly isolated backdrop of the Swiss Alps. This majestic mountain range provides the perfect setting for this epic encounter of two isolated souls. Both Frankenstein and his Monster are like mountains themselves, forces of nature towering over the world beneath. Yet there is a difference. The Monster, unlike his creator, has not chosen to be isolated and alone. On the contrary, as we've already seen, he wants a mate. He yearns for the kind of togetherness that Victor has enjoyed with Elizabeth but which he now rejects in pursuit of scientific glory. With Frankenstein, however, isolation has never just been a necessity, but a conscious choice; it was always part of the plan.
