Why did Rudolf Carnap and Hans Reichenbach establish the journal Erkenntnis?

Rudolf Carnap and Hans Reichenbach established the periodical Erkenntnis (1930–1939) to serve as a dedicated forum for the development and dissemination of the new "scientific philosophy".1

By founding this journal, Carnap and Reichenbach sought to provide a platform for the exchange of ideas between the Vienna Circle and the Berlin group, both of which were composed of scientists and philosophers committed to applying the precision and rigor of the exact sciences to philosophical inquiry. This movement, known as logical positivism or logical empiricism, aimed to establish a "scientific world view" and reject traditional metaphysics as empirically meaningless.21
