Personally, I think his breakthrough is more one generated by force of personality than it is by a logical breakthrough in his Ethics. He also hit on a hotbutton topic for him personally that happens to have an audience in young people. Namely the terroristic nature of some of the doctrines of religion and the damaging effects of many of the punishment norms that parents use in family units. If it was 20 years ago, I’d call him a secular cult leader, and this is from reading through the forums and interacting with some of the members. Some of the members display a level of hero-worship in some of their responses that would concern me if I saw my child falling into it.
I didn’t get far enough with his philosophical discussion, he sells his book, and I wasn’t in favor of buying something I had rejected as impossible previously. The way I have always viewed it is as I stated before, and is I believe informed by an understanding of Praxeology.
He argues for a Universally Preferable Behavior. Meaning that there are some ethical propositions which are always good for all people in all places. I don’t understand how he argues around the finer points.
My view on the whole issue is that Ethics that look for an objective truth or this solution to the Is Ought Problem are observing an evolutionary selection mechanism in the technical implementation level, and trying to make it a law (theory level) instead of simply accepting localized superiority in the competition with competing ethical values which are less fit.
To put it in more pragmatic terms, lying is generally viewed as BAD, because of a very simple logical explanation. If I don’t trust you, you are a risk I must account for in my plans. If I can count on your information as reliable, then I trust you and choose to work with you more often. You reduce my risks.
Lying will still be preferable in many circumstances. Never tell your wife that a dress makes her ass look fat… If you like her ass that way in those jeans let her know, if it’s becuse there’s a certain fatness (or phatness) to it, that you like, then how you give that information to her is up to you. Some information is harmful to others and not necessary to disclose. So, the fitness of dishonesty will generally be low, but it will not always be less fit. This is IMO bounded to the field of Ethics, and the choice of means and ends is (not ought to be, but IS) up to the human actor who uses it.
Now what I did take away from Objectivism is the preeminence of reality. She, and Molyneux, correctly identify that one cannot arbitrarily choose which behaviors to engage in, the social implications of what you choose does alter the perception of others in your social circle. It does feedback to you within the context of those relationships. But mistaking that phenomena as some means of producing Universallly True Ethical Propositions is, IMO a mistake. It attempts to bridge the Epistemological and Praxeological box from within which we act, and that is a trap from which man CANNOT escape.
Dammit, I started to read his argument for Universally Preferable Behavior… I’ll come back to this later and give you a more direct response.
