What is sarah on?

"The way to create new knowledge is to resolve the disagreement by finding a proposal that each person prefers ' a common preference." (source)

CPs are for not hurting each other. they aren't the method by which we create knowledge. (new knowledge? wtf does that mean?) we create knowledge via conjectures and refutations. as written, it sounds like "we create new knowledge by agreeing on stuff". (finding a proposal each person prefers = finding a single proposal about what everyone does that everyone agrees-on/consents-to)
