Nathaniel Hawthorne's book, The Scarlet Letter, represents the ideas of the American Renaissance. This book is a branch of romanticism with its Transcendentalist ideas present in the text. Hawthorne heavily expresses these transcendentalist ideas even though the book takes place in the time of the puritans. 

Romanticism is about emotions and the right way of living. Transcendentalism is the bond between man and nature. Before this book writing was mostly about religion and revolution. Nathaniel used good and evil to show the contrast between the old and new American ideas. This contrast helps show change ideals from revolutionist to romantic.
