Fair enough, I don't fully buy that myself, it just seems the most logical path to me. I can't explain to you how people in the past created the concept of right and wrong because it is so far back. Your own views on that matter are much like mine - they are just speculation.
How would we construct the concept of right and wrong? Well...through careful reasoning? You really don't rely on initial biological feelings to tell you something. I'd feel bad stealing from a hardworking individual. I couldn't care less if a serial scammer was scammed from. From what you are saying, 'biological feelings' tell me stealing is wrong. Perhaps. But ethics and reasoning is what makes you set the scammer apart from the hardworking dude instead of lumping them together. The concept can be created, and it most certainly can be passed down.
Perhaps people in the past did feel this way because they lacked the words or understanding to articulate their feelings and reasons properly. The 'this is wrong just because it's wrong' is a slippery slope argument and will not hold up in any proper debate.
That is a sweeping statement and whilst it may be applicable to many other things in life on this issue I disagree. In any case, there's no point bringing it up because none of us can definitively say 'this is how it happened'. Besides, I don't need to understand what our ancestors thought of murder to know why it's wrong today. Do you?
How do you know? And even if there wasn't, who's to say they didn't just agree on this tacitly or implicitly? Maybe they had their own reasons for doing so, but today we know for sure and can justify why murder is wrong.
You are right, there isn't. The only reason I was here was to try and understand other people's views on this, especially the religious one, because this really is a no brainer for me. Unfortunately Prodromos doesn't seem to be interested in backing up his assertions at all, which by glancing around the forums seems to be his modus operandi, which means I'm probably done here since I'm not really interested in figuring out who thought what thousands of years ago. To be very honest I'm surprised this reached 6 pages of discussion, it's a little unnerving. I would have thought this was an open and shut thing, but looks like you never know
