We look at problems of truth and knowledge from various angles. Insufficient information may prevent the direct use of certain operations, as the use of probability in legal reasoning, so we have to take detours. We may have only contradictory information from different sources, and will use and adjust past reliability of the sources to evaluate the information.Conjectures about homogenousness of the domain may also help.On a more formal level, we extend the formal semantics of counterfactual conditionals to analogical reasoning, and examine Yablo's Paradox using various concepts and examples.
