Letter No. 13 by Ladislav Hejdánek, written in May 1977, addresses the then-topical issue of the emigration of Charter 77 signatories, specifically politician Zdeněk Mlynář. While Hejdánek recognizes the right to leave one's country as a fundamental human right, he critically examines the political and ethical implications of leading opposition figures going into exile. He argues that the struggle for human rights and legality must take place primarily on home soil rather than abroad, viewing the shift of the movement's focus to emigration as a strategic political error. The author reflects on the existential pressure and persecution faced by Chartists but emphasizes the importance of remaining in the country to maintain the continuity of the struggle. Finally, Hejdánek outlines his own reasons for staying in Czechoslovakia, rooted in his connection to domestic traditions and the conviction that the necessary democratization of 'real socialism' can only be achieved from within. The text is a profound reflection on intellectual responsibility and the mission of Czech dissent.
