Write a three-page paper with a strong thesis and good evidence. State the philosophy of the book The Alchemist. How is this philosophy consistent with your beliefs about reality? NOTE: This is not a paper on whether you think the book was good or bad. It is an analysis of how Coelho's view of the world aligns with yours. This must refer mostly to the book, and your thesis will be something like "Paulo Coelho's view of reality is inspiring because..." OR "Paulo Coelho's view of reality is harmful because..." Of course, you will probably use different words to describe his view of reality, but that's the idea. Make sure you have a thesis and evidence from the book to back up your thesis.

This question asks for you to compare the philosophical angles of the text with your personal beliefs. That makes me initially think that the essay could contain the first person; however, the example thesis statements given are stated in a way that excludes the first person. My first recommendation is to mirror the format of the thesis statements given. Very rarely will a formal school essay allow you to use the first person. This doesn't mean you can't state your opinion. You absolutely should. That's what a thesis statement does. The trick is that a thesis is essentially stating your opinion as a fact.
Before beginning to write the thesis and paper, you need to pick exactly what philosophical angle you want to discuss in the paper. The book has themes of love, wisdom, courage, faith, perseverance, and more. You have to narrow it down. Otherwise, the paper isn't going to be very focused. Personally, I would write about how The Alchemist shows readers that the journey is every bit as important as the end goal. You could even argue that Santiago's journey is more important than anything else he obtains in the end. You could relate this to the concepts of carpe diem or "YOLO" (you only live once). If you have to tie it in to a named philosophical worldview, I would look to existentialism.
If you go with the notion that the journey is a better reward than the destination, then a potential thesis could be something like the following: "Although Santiago is desperately seeking a final treasure, he receives far greater rewards from the journey and the people he comes in contact with."
