Probably one of the oldest questions in the book, but I'll ask it again:
How do you personally figure out right and wrong?
I base it on both logic and emotion. I have a gut feeling for what seems right to me and allows me to sleep at night. This feeling can change over time based on information I take in.
I take information in from various sources, including what my parents and teachers taught me, what cultures and their religions from the world have shared, from contemplating things myself, and lastly, from discussing morality in places like this.
I try to do what seems logically best for as many people as possible, though it also has to pass my test of "does it feel right?".
Do you believe only behavior is wrong but not thoughts and feelings?
I don't really look at it as right or wrong. I look at it as useful or not useful, skillful or unskillful, benevolent or malevolent, and so forth. I think these types of terms are better than merely thinking in terms of "right" or "wrong", as these are vague terms.
I analyze behavior by how an action affects the individual performing the action and how it affects other beings.
I analyze thoughts and feelings by how an action affects the individual with those thoughts and feelings. Since these things can't directly affect another, they don't concern me too much morally, but the thoughts one has can weaken or strengthen them based on what they are, so I view some thoughts as elements of weakness and try to remove them from myself.
Furthermore, is our determination of right and wrong primarily subjective?
Yes, at least in a universal sense.
I view morality as subjective because I have yet to see someone form a solid argument for why objectivity can be applied to morality in a universal sense.
Objectivity can only be applied once a goal is agreed upon. At that point, there are objectively better methods of reaching that goal than others, and so morality can be compared on a somewhat objective basis.
If so, don't other people have to be wrong in order that there is a right?
I don't see what you mean or how that's applicable, partly because "right" and "wrong" are so vague.
