To lekton in stoic philosophy and sinn in G. Frege's semantic theory: the question of their epistemological status

The article deals with the comparative analyses of the Stoic category to lekton and G. Frege's category Sinn. This essay explicates some formal features of these categories, which demonstrate certain similarities between the Stoic and Fregean logical theories. It is demonstrated that the concept of the complete lekton (axiōma) in the Stoic doctrine has the same structure as the concept of thought ( Gedanke ) in Fregean semantic theory. However, the formal structural similarity between these concepts does not presupposes the doctrinal similarity of these categories from the point of view of their epistemological status.
