This article looks at Professor Stanisław Jaworski’s contribution to the development of textual criticism in Poland. It was his book I write, therefore I am that offered Polish readers a comprehensive and erudite introduction to French genetic and textual criticism. Published in 1993, it set this enormously important critical movement in the broader perspective of cultural and literary anthropology. The second part of the article examines the impact of this book on Polish studies into the processes of text creation and the ‘avant-textes’. The third, final part surveys the late Professor Jaworski’s role in organizing conferences and stimulating debate on all aspects of genetic criticism.
