So what's your conscience based on?
Evolution? Sure, indoctrination can alter it substantially, but the basic things are (nearly) always there: namely, don't willfully insult or abuse others. Or you'll have a bad conscience, no matter how you rationalize it.
Again, the unspecified "we". Who's the subject? Relative is arbitrary when the subject is the one with the power to decide. But since you maintain that everything is relative, this just winds up to be the case, since someone or some people would have the power to decide.
What warpus said. I cannot decide my biology. Plus there are traditions to consider; whether they're reasonable or not (the traditions I mean), no one wants to become a social outcast.
So what do you think the logic is about? You think ethics isn't logical?
Now that I think more of it, we're talking about the exact same thing.

How much and what kind of ethics is needed seems to be the matter of contention.
After all, it is ethical in itself to
follow your own conscience... For the individual it would make more sense to ignore it in certain situations (as is done quite often).
Tradition, as well as the threat of force, is the answer.
And common sense.
And funny that you should think animal instincts would doom us when you defended evolutionary theory earlier. See the contradiction?
They would doom
civilization, not the species. At this point, following animal instincts would be horrendously ineffective to ensure the survival of the human race. For one thing, population would rapidly decline. And the possibility of colonizing other planets would be lost forever. It may be said that humans govern their own evolution, or at least will in a very real sense very soon (through genetic engineering).
Well, go read about it more. I'm sure even the wiki entry says more than that, if you don't just zoom in on the criticisms. Basically, virtue ethics is about virtues. Ever heard of murder being called a virtue?
Why could it not be a virtue? If a murderer could roam freely without the risk of getting caught, wouldn't it only be natural for him to murder? If he sincerely believed that all the murdered go to paradise in heaven, wouldn't it be
immoral from his point of view to
not commit as many murders as possible?
It's funny that you continue to make assumptions about something you don't know and then stamp your foot when told you're wrong. Doesn't have a complimentary effect on yourself.
In any case, I'm beginning to doubt you're really capable of holding a proper discussion if you think that what I'm saying is you can't be moral because you're godless. I'm sorry, but discussing with people who exhibit willful ignorance always annoys me.
It's called humor.

As for the willful ignorance, yes I sometimes do think of myself more highly than I have the right to. I don't always notice it. But I think even despite all my errors, you still haven't explained a few things satisfactorily (in the "not-go-read-a-book" sense). The reason I 'stamp my foot' is mostly to shake these answers out of you.
I'm sorry, but that statement is just wacky. When I say best, I don't mean best in the myopic mind of someone who can't see past his nose.
What is virtuous to a sociopath then? Does he have no virtues at all? Are virtues always about looking past oneself? If so, why must it be like that? If one has no conscience, 'living the good life' translates in my mind to whatever makes me feel the most pleasure. If that happens to be murder (for pathologic reasons), then so be it.
And your arguments are becoming more and more incoherent. Who's ever excluding your conscience from the picture? If your point is
we must have a good conscience to have a good life, well, yes, duh. You imagine that by being virtuous we might not have a good conscience?
Why? That we may help others? Why must that be everyone's virtue? If a virtue is such for everyone, doesn't the whole word lose its meaning?
Edit: Wait... You said we must have a
good conscience, not
a conscience for a good life. I can see how a good conscience can be better than a constant neutral feeling (no conscience at all). In that it is more pleasurable. But what if murder produces enormous personal pleasure?
Lastly, I don't care what you think. I'm not trying to sell you a product. You can believe in whatever you want. I'm not a Christian trying to convert you. You wanna be an idiot and think nonsense about something because you can't be bothered to find out for yourself? That's your problem. Have fun.
I am, thank you very much.

Since I cannot squeeze satisfactory answers out of you, perhaps I really should go read a book. However, there are a lot of books to read in this world, which is why I was hoping you could provide some answers, since you've read some of these 'moral' books. I think it is a matter of either my thick-headedness and none-educatedness, your unargumentativeness, you/me/us missing something essential, or quite likely a mix of these three. If you'll answer me one more time and I still won't 'get it', I'll then promise to read one good book on the matter if you can recommend one.
