Ion Grigorescu’s diaries from the crucial years of 1970 to 1975 are a small literary and art-historical sensation. It not only corrects the facile reading of Grigorescu’s practice in the context of Conceptual art and performance, but provides insight into the artist’s multifocal thinking, which incorporates an original critique of modernism, the dystopian effects of an instrumentalized idea of reason and rationality, and an analysis of subjectivity.
