In Nathaniel Hawthorne's "Dr. Heidegger's Experiment", I was asked to figure out how Hawthorne feels about transcendentalism. We determined that Dr. Heidegger represents Ralph Waldo Emerson, a transcendentalist. However, I can't decide if Hawthorne thought transcendentalism was ridiculous and overly-optimistic or if he was making fun of it or praising it???? I think that determining whether or not the water the old people drink is really full of youth or not is important, but Hawthorne leaves that open to interpretation. So, I am totally confused about what he feels about transcendentalism. If anyone can help me on this, I'd really appreciate it.

You are thinking too hard. Hawthorne was poking fun at them, they dressed weirdly, and were odd. Read this:

To determine how Nathaniel Hawthorne feels about transcendentalism in his story "Dr. Heidegger's Experiment," we can analyze various elements of the text. While it is true that Dr. Heidegger can be associated with Ralph Waldo Emerson, a prominent transcendentalist, Hawthorne's intention may not be straightforward.

Firstly, consider the characterization of Dr. Heidegger. He is portrayed as a somewhat eccentric figure, conducting unusual experiments and surrounding himself with aged individuals. This portrayal may suggest that Hawthorne is poking fun at the transcendentalists, as you mentioned. The portrayal of the characters' oddities and the element of satire in the story could support this interpretation.

Moreover, examining the theme of the story can provide insights into Hawthorne's perspective. "Dr. Heidegger's Experiment" explores the desire for eternal youth and the consequences of pursuing it. The story raises questions about the authenticity of the water and whether it truly rejuvenates the individuals or simply fools them into thinking so. This ambiguity allows for multiple interpretations, leaving the reader to question the nature of transcendentalism and its promises of enlightenment and optimism.

While the source you provided may assert that Hawthorne was poking fun at the transcendentalists, it is essential to consider multiple perspectives and interpretations before drawing a definite conclusion about the author's intention. Analyzing the text, exploring relevant themes, and examining historical contexts can all contribute to a better understanding of Hawthorne's portrayal of transcendentalism in "Dr. Heidegger's Experiment."
