The emphasis is on the research approach applied in the last monograph of Prof. Nikolay Milkov. It is about studying the early sources of analytical philosophy, and especially in German literature from the late nineteenth and early twentieth century, he dwells on the Bulgarian philosophers Dimitar Mihalchev and Tseko Torbov. Dimitar Mihalchev publishes in German a monograph “Philosophical Studies. A Contribution to the Critique of Modern Psychologism” (Leipzig, 1909), which J. Moore evaluated. Tseko Torbov is an assistant to (...) the neo-Kantian Leonard Nelson. Prof. Nikolay Milkov does not fail to mention these small presences of Bulgarian philosophers in the Western European intellectual panorama. (shrink)
