This article draws on some of Martin Heidegger's ideas to examine the functioning of the mode of self-imposed silence ('falling silent') in the poems of Tadeusz Rózewicz. Crucial to this inquiry is the question about the meaning of Rózewicz's gesture of stopping and giving up writing. It may represent his deliberate choice of 'the space of non-naming', the relinquishing of words in the face of mystery, or falling silent after reaching an extremity beyond which it is impossible to move. The article also presents some strategies of deconstructing the subject employed by Rózewicz. In the context of the preceding discussion they appear as a deliberate activity opening up the perception of being.
