«Prague has become known as a centre for Brandomian Inferentialism, and with this as a tool, Pavel Arazim offers us a broad and insightful overview of recent problems and views regarding logical reasoning as a human activity.»

Göran Sundholm, Professor of Logic (emeritus), Leiden University, The Netherlands

«Arazim’s highly original book shows how formal logics is the study of syntacto-semantic forms of sentences and inferences, following ideas of Brandom and Peregrin. It is recommended as absolutely basic for philosophy of language and information processing to students and scholars of philosophy, linguistics, mathematics, computer science and history of science.»

Prof. Dr. Pirmin Stekeler-Weithofer, Senior Professor of Theoretical Philosophy, University of Leipz

«Arazim's book provides a fresh look on the widely discussed problem of the plurality of logics - not fresh in the sense of ignoring what has been said about it up to now, but rather in that of a careful and novel reconsideration of the philosophical tradition dealing with this issue.»

Jaroslav Peregrin, Research Professor, Institute of Philosophy, Czech Academy of Sciences, Czech Rep
