Final answer:
Virtue ethics is the approach that emphasizes the importance of character and virtue for ethical behavior, advocating that right actions stem from a person's good character traits.
Step-by-step explanation:
The concept that argues ethical behavior involves not only adhering to conventional moral standards but also considering what a mature person with a "good" moral character would deem appropriate is virtue ethics. This approach to normative ethics emphasizes the role of character and virtue in moral philosophy rather than either the consequences of actions or adherence to a set of rules.
Virtue ethics advocates for the development of good character traits and habits, suggesting that right action flows naturally from a virtuous character. This is in contrast to other ethical frameworks like consequentialism, which evaluates the morality of an action based on its outcomes, and deontology, which focuses on adherence to moral rules or duties.
