Answer:
Plato
Step-by-step explanation:
Plato's conception of ethics are totally based on virtue. He believes that ethics and morally right behaviors are as a result of wellbeing and happiness felt by individuals, and regards this as the highest aim of moral conducts, while virtues are the needed skills to achieve this. Thus, he believes that all humans are born with a knowledge of what is right and wrong. Hence this beliefs are consistent with that of Professor McClure from the question, as he believes young people can make correct decisions because of this in-born knowledge of what is right and wrong.
