First of all i thought i ought to comment on Wasabi's comment. I attend a Catholic highschool and am currently taking grade twelve Philosophy. Although it focuses on many subjects not all Bible Related (as the course replaces taking Church and Culture), the general background includes God. Although I personally have my own opinions on church and religion, I thought i should mention that philosophy can very much tie into God.
Second, to answer your question, that is very much a topic of ethics and morality. Thomas Aquinas (who had an Aristotelian view) very much believed in three types of virtues; intelligence, moral and theological. Each can lead to another, but he believed that all three were key to morality and discovering right or wrong. In fact, he believed that God gives someone the ability to see right or wrong.
The problem is, "right or wrong" is very difficult. One may argue that each feel differently. Others may argue the instances where some are unable to distinguish right or wrong. The truth is, right or wrong walks hand in hand with 'just'. what is just? These are questions philosophers still ponder today.
