Jan Patocka outlined the basic principles of his phenomenology in the 60ies, when a possibility appeared for him to publish them in Slovakia. He influenced the Slovak philosophy by his contributions on the history of Czech philosophy, by his critical evaluation of the philosophy of Czech history (especially that of Masaryk), as well as by developing his double concept of nation in Czech tradition (the language-cultural and social-ethical ones). Also in his outlines of Czech philosophy he occasionally reviewed the writings of Slovak philosophers. In the interpreting of philosophy of 'small nations' his concept of 'marginal philosophy' might be inspiring.
