Finally, the twentieth century theologian Karl Barth’s famous “No!” to philosophical reasoning about God is also best understood as a rejection of philosophical overreach rather than a rejection of philosophy per se (Brunner &amp; Barth 1946). According to Barth, we cannot establish the truth of theological claims using generally persuasive arguments available to any rational enquirer. But Barth had no quarrel with using philosophy in an Anselmian mode, to elucidate and clarify the implications of divine revelation, and in principle he even allows that there could be a genuinely Christian philosophy (1932 [1975: 6]; Diller 2010).
