How do you convey thinking there is no objective truth value to any moral statement and then convey that something is forbidden?
Sure, I can. Doing something that is forbidden, results in harsh consequences (that other agents impose), that is the only meaningful definition I can come up with. Can you come up with any other useful definition?
I like to stick with other people's definitions and not come up with my own. Merriam-Webster for example:
1: not permitted or allowed
Thanks for being my straight man! :)
Do you believe in an objective morality capable of being scientifically investigated (a la Sam Harris *or others*), or are you a moral nihilist/relativist? There seems to be some division on this point. I would have thought Less Wrong to be well in the former camp.
Edit: There seems to be some confusion - when I say "an objective morality capable of being scientifically investigated (a la Sam Harris *or others*)" - I do NOT mean something like a "one true, universal, metaphysical morality for all mind-designs" like the Socratic/Platonic Form of Good or any such nonsense. I just mean something in reality that's mind-independent - in the sense that it is hard-wired, e.g. by evolution, and thus independent/prior to any later knowledge or cognitive content - and thus can be investigated scientifically. It is a definite "is" from which we can make true "ought" statements relative to that "is". See drethelin's comment and my analysis of Clippy.
