The paper presents the logical milieu of the Paradox of ravens, identified by Hempel in his Studies in the Logic of Confirmation. It deals with Hempel’s interpretations of Nicod’s criterion of confirmation as well as with its inadmissible consequences. I, subsequently, suggest an epistemological and semantic specification of empirical properties, i.e., of their identity; then I formulate a criterion of the test of properties expressed by empirical hypothesis. Finally, I propose a procedural conception of confirmation by means of the testing procedure schema. The confirmation is, therefore, conceived as an attribute which can be ascribed to a hypothesis through the process of its testing. The methods of testing are central to the hypothesis’s qualifica-tion as confirmed.
