The following two books are used in the course:
Immanuel Kant: Critique of Pure Reason. Translated & edited by Paul Guyer and Allen W. Wood. Cambridge University Press. 1998 or later. (Werner Pluhar's translation is also acceptable; others should be avoided.)
In case German or Norwegian is preferred, the German editions of Kritik der reinen Vernunft that include both 1st and 2nd (A:1781 & B:1787) edition, as well as the Norwegian translation "Kritikk av den rene fornuft" (translated by Camilla Serck-Hanssen), can also be used.
