Final answer:
The assertion that feeling good about an action implies it is ethical is false. Ethical decisions are based on moral principles, which may not always align with personal satisfaction or individual desires. It is crucial to differentiate between subjective feelings and objective morality in ethical reasoning.
Step-by-step explanation:
The statement 'If you feel good about something you've done it must have been an ethical choice' is false. The feeling of personal satisfaction does not necessarily align with ethical principles. Ethics involves a set of moral principles that govern a person's behavior or the conducting of an activity. Simply feeling good about an action does not determine its moral value.
For example, an individual may feel good about not sharing resources with others, based on ethical egoism, which suggests aiming at one's own greatest good. However, this can be at odds with objective moral reasoning where actions are assessed against broader goals, such as the well-being of others or societal norms.
Ethical naturalism, for instance, would argue that what feels good could just be a reflection of individual desire, which may or may not align with what is morally correct according to natural facts or laws. Therefore, it is critical to distinguish between personal feelings and ethical objectivity when making moral judgments.
