Passage Summary: Junk mail is wrong because it wastes a ton of paper that never gets read, and we wouldn't let an individual get away with that much waste.

Conclusion: The business practice of using direct mail advertising is both annoying and immoral.

Reasoning: Direct mail is usually thrown away unread, resulting in a massive waste of paper that would be considered unconscionable if anyone else did it.

Analysis: Durth's method involves establishing a moral standard by comparing a business practice to the behavior of individuals. By stating that the same level of waste would be 'unconscionable' for anyone else, the speaker argues that businesses should be held to that same ethical standard. To identify this method, focus on how the argument applies a general moral principle to a specific case through a comparative judgment.
