ABSTRACT. Davidson claims that nothing can count as a reason for holding a belief except another belief. Gluer argues that Davidson shifts the focus of attention from the concept of a language to that of communication by language. Davidson suggests that the existence of lawlike statements in physical science depends upon the existence of constitutive laws like those of the measurement of length within the same conceptual domain. Davidson writes that the relevant stimuli are the objects or events we naturally find similar which are correlated with responses from the child we find similar.
