What we have here are two (or more?) opposing groups of intelligent people, believing the other group(s) are spouting nothing much more than inane nonsense. What I would like to do is break down some of the arguments opposing mine a bit more, just in (the unlikely) case that I am the one spouting inanity after all.
For ALL Those Who Still Think "Ought" Can Not Be Derived From An "Is":
A few questions I would like to ask you:
What is the value of keeping 'is' and 'ought' as separate concepts? What do we get out of keeping such a distinction in place? What would we be missing, if we melded the two together?
Your answer can appeal to anything you think is important: Philosophy, science, morality, etc.
What is the DANGER of trying to derive Ises from Oughts? I would like this answer to be spelled out as clearly as possible, even if that risks pretending that I am in kindergarten or something. There could be something very fundamental I am missing, here.
Also, if possible, perhaps you can define the word "Is" and "Ought", and (optionally) perhaps even "derive"? What contexts or levels of morality forming would these words apply to?
After I feel enough people have provided answers (OR, if a lot of time passes, with hardly any answers), I will write further responses to this thread. But, I am willing to give you folks some fairly good amount of time to formulate your answers if you need it.
