Questions: Which of the following is a reason why deontology may be difficult to apply? People disagree about what duties we owe to one another and whether the consequences of their decisions are positive or negative. People disagree about the right course of action to take in terms of building and maintaining human relationships. People disagree about what duties we owe to one another and which duties are more important than others when they conflict. People disagree about what duties we owe to one another, whether the consequences of their decisions are positive or negative, and the right course of action to take in terms of building and maintaining human relationships. People disagree about whether the consequences of their decisions are positive or negative.

The answer is: People disagree about what duties we owe to one another and which duties are more important than others when they conflict.

Explanation for each option:

1. People disagree about what duties we owe to one another and whether the consequences of their decisions are positive or negative.

   • This option is partially correct but not comprehensive. Deontology focuses on duties and rules rather than consequences, so while disagreements about duties are relevant, the emphasis on consequences is more aligned with consequentialist theories like utilitarianism.

2. People disagree about the right course of action to take in terms of building and maintaining human relationships.

   • This option is more relevant to virtue ethics, which emphasizes character and relationships, rather than deontology, which is more concerned with adherence to moral rules and duties.

3. People disagree about what duties we owe to one another and which duties are more important than others when they conflict.

   • This is the most accurate option. Deontology can be difficult to apply because it often involves determining which duties take precedence when they conflict. For example, the duty to tell the truth might conflict with the duty to protect someone from harm.

4. People disagree about what duties we owe to one another, whether the consequences of their decisions are positive or negative, and the right course of action to take in terms of building and maintaining human relationships.

   • This option is overly broad and includes elements that are not central to deontology. While disagreements about duties are relevant, the focus on consequences and relationships extends beyond the scope of deontological ethics.

5. People disagree about whether the consequences of their decisions are positive or negative.

   • This option is more relevant to consequentialist theories. Deontology is primarily concerned with the morality of actions themselves, rather than their outcomes.

In summary, the primary challenge in applying deontology lies in determining which duties are most important when they conflict, making option three the most accurate.
