In this article I attempt to investigate the way a thought or a feeling acquires the conviction of psychic reality. I suggest that realizations emerge out of discontinuities. Caesura represents the paradox of discontinuity that emerges out of the underlying continuity. Bion's clinical and theoretical development exemplifies this perspective. It introduces a transformation of the notion of loss as the engine of development. The horizontal row of Bion's grid is used to represent the development of realizations. A clinical vignette illustrates my reflections on this process.
