Age of Reason and Puritanism in The Great Gatsby.

      For the Puritans, God always came first. For Gatsby, it came down the self improvement, getting the ladies, and having money as priorities."Rise from bed at 6:00 a.m., Dumbbell exercise and wall scaling 6:15- 6:30, Study electricity, etc 7:15-8:15, work 8:30-4:30 p.m., baseball and sports 4:30-5:00, Practice elocution, poise and how to attain it 5:00-6:00, study needed inventions 7:00-9:00" (173). 
In the quote above it is showing what Gatsby does in order to self improve, and it also shows us how he will accomplish a "better self". This type of thinking process which is taking place inside of Gatsby's mind shows that Gatsby himself is an example as a whole, of someone who represents Age of Reason.                         
      Romanticism also takes place in the novel as a writing trend which is also expressed by Gatsby. 
Romanticism from what I have collected means not only "love" topics, but that you have everything being perfect and living happily without major problems. In the book, the way Tom Buchanan's lives, (his living style) represents this era because his house is really big and it gives us the stereotypical idea that because he has a nice/big house, that he is rich and happy, unlike Gatsby who has problems getting money, because the money he is getting is being earned at the bootlegging business.
