During his summer experiment, victor admits "his eyes were insensible to the charms of nature." what role might nature (or the lack of it) play for victor?

His lack of nature disconnects him and makes a laceration between himself and everything that does not pertain to his project. He also starts to neglect his family through a lack of communication which causes him to ignore them. Although his main purpose was to create the life he focuses on the negative aspects of it which resulted in the distortion of his true goal. His being away from the true beauty of nature made him ignorant to the very thing that his creation was to promote.
