A significant share of the “struggles” that took place within Czechoslovak inter-war philosophy lay in criticism raised by Emanuel Rádl, the representative of the realistic approach, against the adherents of individualism or the younger philosophical generation surrounding the magazine Ruch filosofický. From a philosophical and methodological point of view, the core of Rádl’s critical position is philosophical realism. Rádl’s realistic stance was gradually forming and developing during the periods running up to and following the First World War, while the experience and fear of the consequences of Russian philosophy based on mysticism, intuitivism and idealism, proved to be the tipping point. Besides that, the change in his stance towards Kant’s philosophy, which consisted of highlighting the positive aspect of his rationalism, was yet another significant turnabout. From his post-war realist position, Rádl proceeded to criticise the alienation, apoliticism and amorality of the philosophy of individualism and the interest of its representatives in the philosophical approaches of irrationalism: mysticism, intuitivism and spiritualism.
