Final answer:
An individual's behavior is ethical when it aligns with moral principles, often meaning acting in the best interest of society rather than focusing solely on personal gain or profitability.
Step-by-step explanation:
A person's behavior can be considered ethical when they act in a way that is aligned with the basic principles governing moral conduct. Acting in the best interest of society often reflects such principles. While egoism may play a role in decision-making, ethical behavior generally involves going beyond narrow self-interest. For instance, individuals may pursue their own interest in economic contexts but then prioritize others' interests in social situations. This demonstrates the ability to balance self-interest with the welfare of others.
Meta ethics explores these theories and dictates that simply acting in accordance with what is most profitable or beneficial to oneself (ethical egoism) does not equate to being ethical. Instead, a focus on societal benefit, informed by an individual's inner conscience and sense of right and wrong, underpins ethical actions. Therefore, to say that one acts ethically, it must involve a consideration of the broader impact on society rather than just personal gain.
