Almost all discussions in this subforum could benefit from a discussion of the term "ethical." To start, I would like to invite a guest speaker to give his opinion on the subject:
Conan's response to the most fundamental ethical question raises two points:
1) There is a commonly-missed distinction between the field of Ethics and each person's definition of ethics in practice (ethos). The field of Ethics argues about what the ideal should be, based on logic. Ethos is what a given person or community actually values and believes, potentially based on nothing at all.
2) Ethos can vary substantially and are frequently defined by society, but even within a society there is significant variability. People, even including philosophers, frequently let any variability in ethos quickly devolve into the meaningless quagmire of ethical relativism. Remember, Ethics would be useless if it was just a field based on opinion. People can be wrong even if they sincerely believe that they're right.
For an actual discussion of ethics, you first have to define your base truth. What is this "greatest good" that you are trying to optimize with your decisions between right and wrong? Your happiness? The happiness of your social group? Human happiness? Adherence to rules in a religious text?
If you cannot answer this question or if you believe that there can be multiple valid answers, then you cannot make any objective ethical statements because you have no logical grounds on which to base any future argument. This is the so-called "ethical relativism," where something can be fine in one culture that's not fine in another. As an example, is entering a 1000-person village with 200 young male friends, killing the men, and raping the women a good thing to do?
A) Optimizing personal happiness: Yes, because it makes me happy for a few days. (example: hedonist)
B) Optimizing friend happiness: Yes, because it makes me and 200 of my friends happy for a few days. (example: Conan)
C) Optimizing human happiness: No, because it makes 1000 people suffer for the rest of their lives and only 200 people happy for a few days.
D) Optimizing God's happiness: Depends, but probably yes as long as we follow a few rules and convert people to his/her religion. (example: Boko Haram)
Now, I will warn you here that the question "What is best in life?" is just a convenient place to start an ethical debate. If you can't logically justify your answer then you're not going to be very convincing. Still BG, I ask you, "What is best in life?"
