Answer:
Because the transandentalists were humanists and believed that they could live life in a communist "type" community with themselves as God. The Puritans on the other hand lived there life for God and in a system where each house hold was dependent upon working in a capitalist type system. The Bible says,"If you don't work you don't eat." This was part of their philosophy as well. In The Scarlet Letter, Nathaniel Hawthorne was not looking particularly favorably on the Puritan way of life in some respects, making it look cold and harsh. Hawthorne had been part of this transcendentalist's"communist" type society for only about a year. He quickly found out that even though he paid his part to be part of the society, not EVERYBODY there had the same intentions he had "to work hard for the good of the society."
At least, I'm quite sure about this.
