Final answer:
Duties of good faith and fairness are morally owed to a third party in a transaction, as per philosopher W.D. Ross's prima facie duties which dictate honesty, genuine effort, and equitable dealings.
Step-by-step explanation:
The duties owed to a third party in a transaction can vary based on the context, but in terms of moral commitments, as outlined by philosopher W.D. Ross, two key duties might encompass dealings with third parties: good faith and fairness. Good faith is a fundamental aspect of many legal and business transactions, implying honesty, making a genuine effort, and not deceiving the other party. Fairness operates along similar lines, dictating that one ought to be just and equitable in their dealings and consider the interests of all parties involved.
Ross identified other duties such as fidelity (keeping promises and being truthful), reparation (making up for wrongs), gratitude (being thankful and reciprocating), promoting good (enhancing overall well-being), and non-maleficence (not causing harm). Keeping in mind that Ross's framework is a moral guideline and not a legal template, in relation to third parties, we may infer that the duties of competency, good faith, and fairness should all be upheld in relationships and transactions involving third parties.
