Final answer:
The term 'reasonable' in an ethics code calls for rational and fair judgment in accordance with professional and societal standards, and may contrast with normative ethical relativism by asserting universal ethical principles discerned through reason.
Step-by-step explanation:
The definition of 'reasonable' in an ethics code usually means applying a level of judgment that is based on common sense, rationality, and fairness, as understood within the context of a particular profession or societal norm.
For professionals interpreting ethical codes, such as those outlined by the IEEE-CS for software engineers, it involves making decisions that are aligned with both the explicit rules of the code and the overarching principles of promoting safety, respecting privacy, and not harming the environment.
When contemplating ethical situations, one might consider the theory of normative ethical relativism, which suggests that ethical truths depend on the individual or group holding them. However, many argue that reason provides a universal foundation for ethics, enabling the discovery of ethical principles with broader application.
In essence, determining what is 'reasonable' involves a balance between ethical theory and the practical implications of their application, necessitating careful deliberation and often reflecting a consensus or a compromise that is deemed acceptable by a cultural or professional community.
