Josef Čapek is less brilliant, less the virtuoso, less extrovert than the other Čapek Dioscurus. It might sound paradoxical, but Josef Čapek – painter, man of the world of shapes and colours, space, the external – is infinitely more introverted. And his art! This introversion made a thinker of Josef Čapek. But not a thinker in any professional sense. After reading all the books and essays in which Čapek immerses himself deepest in those issues that matter to him most we will not hesitate to deny him the title of philosopher.
