Wait... I'm not sure what an 'absolutist negative' is, but are you saying you do understand what it was like to live in that time, or that you're not sure and need proof of what century you're from...?
S'far as I can see, everything we know about the past is gotten from bones, broken pottery, biased manuscripts and ruined buildings. How're we supposed to be sure of anything?
I'm saying that emerald can't really prove all his claims, even though he's essentially correct. We can't really know what it was like without having lived it ourselves. That said, life wasn't the same for everyone back then, and it would be silly to think that everyone agreed with eachother on everything.
As far as knowing stuff about the past... we have more than just bones and pots. We have art, literature, historical accounts... lots of stuff.
Well yeah, I guess, but then by your logic
everything is right, because for every thing, there's always someone somewhere who's believes it's right. So, thusly, it would be 'wrong' to discriminate against the sicko who likes to cut off innocent people's heads and do a voodoo dance around it, because who are we to say that's not right?
I understand where you're coming from; everyone has their own beliefs - but there will always be a sole set of beliefs underneath it all - passed down from your parents, like Mr. Fool said - that will make you not wanna kill folks, and help people, etc.
Beliefs inherent in our society - just like burning witches was in the past. Presumably. Otherwise it wouldn't have been such a wide practice...
