In Paulo Coelho's "The Alchemist", both irrational thoughts and omens acted like a guide for the characters decision making, as it had in Harper Lee's "To Kill a Mockingbird", Don Marquis' "The Lesson of the Moth", and Demons by Imagine Dragons.
When Santiago just got robbed in the marketplace, his fear and sadness took control of thoughts. "But the marketplace was empty, and he was far from home , so he wept. He wept because God was unfair, and because this was the way God repaid those who believed in their dreams"(Coelho 42).
"Maycomb County had recently been told that it had nothing to fear but fear itself"(Lee 6).
Just as fear had been a irrational thought for Santiago, In Harper Lee's "To Kill a Mockingbird" fear had been the cause of revolt for the town against Tom Robinson's case.
When Santiago told the alchemist that he did not want to pursue his personal legend, the alchemist reminded him that his personal legend was important and should always be followed,"You'll spend the rest of your days knowing that you didn't purse your Personal Legend, and that now it's too late"(Coelho 124).
As Santiago was taught to follow his personal legend, in the Lesson of The Moth by Don Marquis the moth had believed in following his own "Personal Legend" by burning himself on the flame.
When Santiago first met the King, they were talking about omens and the importance of the omens,"In order to find the treasure, you will have to follow the omens. God has prepared a path for everyone to follow"(Coelho 31-32)
As Santiago believed in and followed the omens, the song Demons by Imagine Dragons was a type of omen for the listener to believe in.
In life non-rational or irrational thoughts control us, no doubt, but it is how you have dealt with these that matter. As Santiago from the Alchemist followed omens and was changed by irrational thoughts or feelings, so was the characters in "To Kill a Mockingbird", the moth in The Lesson Of the Moth, and the listener of Demons.
