 Basing relations may be involved in both inferential and non-inferential justification. For example, one may hold that sensory states count as reasons, and thus require that a sensory belief be based on a reason if it is to be justified by that reason. In addition, one might understand at least some self-evident beliefs to be based on the meanings of the various terms of the sentence expressing the proposition believed. For example, one’s belief that all bachelors are unmarried men may be understood to be based on the meanings of ‘all’, ‘bachelors’, ‘are’, etc.
