The level of civilization in Texas definitely wasn't very high if the old man was an example of it.
The quote from Larry McMurtry's "Lonesome Dove" comments on the perceived low standards of civilization in Texas during the time depicted in the novel. The character of the old man signifies a representation of the societal norms and values, suggesting that if he is typical, then the overall civilization must be lacking.
This perception serves to highlight the ruggedness and challenges of life in Texas, reflecting the harsh realities faced by its inhabitants. The comment prompts readers to contemplate the complexities of civilization, progress, and what it means to be 'civilized' in such a frontier environment.
