the word "freedom" isn't specific and clear enough. same for "liberal", "liberty", "reason" or "rational".
the words "humility" and "modesty" are too negative and have mistakes mixed in. their synonyms are worse.
"decentralized" doesn't get the point across well, it's too much of a special case.
"non-justificationist" would not be understood, nor would "fallibilist".
The word "independence", like some of the others, is too connected with politics not philosophy. also, like some of the others, lots of people who are pro-authority would be in favor of it and not see the contradiction
"cooperation" is too specific (not covering all the meaning) and people won't understand the connection
"no-authority" or "anti-authority" are both defining it in terms of what it's not. i want a word which means the right concept, rather than just denying an opposing view
some other potentially useful words are, "self-rule" (which sounds way too much like being your own authority), "self-determination", "autonomous"
btw if you look up the antonyms of "authority", they are terrible. they are words like weakness, powerlessness, inferiority, and disadvantage. that is what people think lack of authority is like. it tells you something about how badly they want authority, and see authority as a major goal and all around desirable thing. http://thesaurus.com/browse/authority
it's really sad, and says something about our culture, that there's no anti-authority word that is on par with the word "authority" for clarity, being well known and understood, applying broadly, and other things one would want from a word which make it easy to use effectively. like you can use "authority" for both political and epistemological discussions and people won't blink, they won't find it at all odd, weird, confusing or objectionable, it's just natural. but with a word like "independence", that's primarily a political word, and people will hesitate if they see it in a philosophy context.
one place I'd like to use this word is a slogan. something kinda like:
initiative, responsibility, criticism, persuasion, humilitythe other words there are decent enough but "humility" is bad
another reason i want a no-authority word is for epistemology discussion. i've identified rejection of authority as perhaps the most important theme of the good epistemology, more than fallibilism, criticism, rationalism, objectivity, or existence (Rand considered "Existentialism" before "Objectivism", but it was taken).
i think the top two epistemology concepts are no-authority and error-correction. both are implied by fallibility but no one knows that. (nor do they know much about the relationship between the "critical" in "critical rationalism" and error-correction).
they also both imply each other. the rejection of authority entails needing to worry about error (as opposed to trusting authority to be right). and correcting errors requires considering the merits of ideas, rather than their amount of authority.
another word that would be nice is error-correction as one word. but that's not so important because error-correction is a descriptive phrase that positively identifies the right thing to do, without mentioning any opposing view.
another word I'd like is a positive word for non-TCS-coercion. "common preference finding" doesn't work well, it's too specific and is jargon.
another word I'd like is a positive word for non-force. there's "peace" but that's for groups not an individual level. there's "cooperation" but using that word does not communicate to people "no force allowed". people will consider relationships involving some force to be "cooperative". there's "voluntary" and "consensual" but they don't really capture it.
