Cawelti’s assessment from The Six-Gun Mystique. His description of the Western formula being “far easier to define than that of the detective story” may clearly be a paradigm for many authors, but not particularly for Stephen Crane. The standards Cawelti has set forth for a successful Western is quite minimal by thought, but at the same time relevant. Crane signifies a different perspective to these standards. Crane’s thoughts for the use of the Western formula are just approaches...
