 As Bolzano was well aware, analyticity in his general sense entails neither necessity nor apriority (TS, §197). [Truman, who was president of the USA in in the 20th century, was male], for instance, is universally valid with respect to [Truman], and thus analytic according to Bolzano’s definition. Clearly, his use of the term ‘analytic’ differs radically not only from Kant’s, but also from later uses of the term in the writings of Frege, Carnap, and others. This has led to some misunderstandings on the part of some of his later readers (e.g., Bar-Hillel, 1950).
