Charles, In experience-based learning there are two main problems relating to knowledge acquisition: you have to come up with hypotheses and you have to assess their plausibility. Theoretically, you can regard all hypotheses, but you can't actually do it explicitly because of combinatorial explosion. Instead you create them based on various heuristics. Assessment of plausibility also can't be based on proof most of the time, as new knowledge isn't analytic, it asserts something about the future even though future hasn't happened yet. So, various assessments of plausibility based on usefulness or support by evidence need to be kept track of. As those 'theories' are not limited to explicit language-level statements, they cumulatively can provide all needed facets of meaning.
