The "entailment thesis", or the principle that knowledge entails belief, is accepted by most epistemologists today. However, not everyone agrees. Some philosophers have presented at least prima facie convincing counterexamples. It seems, however, their challenges have been not so much answered as simply neglected. After examining two types of attractive, but not completely satisfying answers to such purported counterexamples, I will propose an alternative answer, which seems to be congenial to the spirit of epistemological naturalism.
