It features an article by Walter Pedriali entitled, “The Logical Significance of Assertion: Frege on the Essence of Logic”. Here is an abstract:
Assertion plays a crucial dual role in Frege’s conception of logic, a formal and a transcendental one. A recurrent complaint is that Frege’s inclusion of the judgement-stroke (the formal counterpart of assertion) in the Begriffsschrift is either in tension with his anti-psychologism or wholly superfluous. Assertion, the objection goes, is at best of merely psychological significance. In this paper, I defend Frege against the objection by giving reasons for recognising the central logical significance of assertion in both its formal and its transcendental role.
