Kai Sørlander born 1944, studied philosophy at the University of Copenhagen and wrote a gold medal thesis on Wittgenstein's early philosophy. After that, Sørlander went his own way and developed an independent philosophical position, which Georg Henrik von Wright, Wittgenstein's successor as professor at Cambridge, has characterized as "post-Wittgensteinian Kantianism". This philosophy is primarily elaborated in the books The Inevitable (1994), The Ultimate Truth (2002) and Introduction to Philosophy (2017). In addition, Sørlander has also written several political-philosophical books, including On human rights (2000), Defense of rationality – religion and politics in a philosophical perspective (2008) and The political commitment – ??the philosophical foundation for democratic decision-making (2011). In addition, Sørlander has also written a large number of chronicles and articles.
