Slim is the most respected person on the ranch. Steinbeck's descriptions of him suggest an idealised characterisation. He exerts a natural authority as a result of his strong moral sense. His opinions are valued by all of the ranchers and his pronouncement about Candy's dog, "he ain't no good to himself", seals its fate. In addition, his superior status is reinforced when Steinbeck attaches images of royalty to him through his use of divine imagery, for instance, "majesty" and "prince"
I hope that helps!!!
