Notebook R: Human Relations is a book of aphorisms that examines the depth and the scope of human relations in different contexts, whether it is between family members, friends or strangers. While the author, Yunus Tuncel, dives into the background of these relations, it brings out the uncanny in these relations, the link between the familiar and the unfamiliar, their conflict and reconciliation in the ever-changing landscape of relations. In what ways are human relations limiting and repressing, and in what ways are they liberating and enhancing? As some of the aphorisms address these all too human questions and problems, some others investigate power structures in relations, whether they be lateral or vertical. In short, the aphorisms of the book plunge into the often unspoken chasms that lie among human beings.
