Final answer:
A conflict between two perfect duties can be resolved by applying the principle of double effect, which considers both the intent and consequences of an action.
Step-by-step explanation:
In ethics, a conflict between two perfect duties, such as never tell a lie and avoid harming someone, can be resolved by applying the principle of double effect. According to this principle, an action that is intended to achieve a morally good outcome but also has an unintended negative consequence may be morally permissible if certain conditions are met. For example, if telling the truth were to harm someone, an individual may be justified in remaining silent or finding a way to communicate the truth without directly causing harm.
The principle of double effect takes into account both the intent behind an action and the foreseeability of its consequences. It recognizes that certain actions may have unintended negative consequences that are outweighed by the positive intent and overall outcome. However, it is important to carefully consider the specific circumstances and consequences before making a decision.
