"...rules and particular inferences alike are justified by being brought into agreement with each other. A rule is ammended if it yields an inference we are unwilling to accept; an inference is rejected if it violates a rule we are unwilling to amend. The process of justification is the delicate one of making mutual adjustments between rules and accepted inferences...." (Nelson Goodman, Fact, Fiction and Forecast)
