What is captian Waltons chief concern?

Captain Walton's chief concern in Mary Shelley's "Frankenstein" is his relentless pursuit of knowledge and discovery, particularly regarding the exploration of the North Pole. He is driven by a desire for glory and the ambition to make significant scientific contributions. Additionally, Walton is concerned about the isolation and loneliness he experiences during his voyage, seeking companionship and validation from Victor Frankenstein, whom he encounters in the ice. This duality of ambition and longing for connection underscores his character throughout the narrative.
