"The gradual, more or less thinning out of the paint also intimates the possibility of complete disapparance.  Thus, especially the paintings that have been washed out to a particularly large extent suggest less a process of creation and more a sense of increasing evaporation.  The presence of what is visible in each case thus appears as a possible, but not necessarily, permanent state.  By virtue of the fact that seeing these paintings - as a following of the traces of a past action that cannot fully be comprehended in terms of its ultimate outcome - is so forcefully connected with the respective experience of one's own presence, it is not only the permanence of what has just been seen that seems to have been called into question, but also one's own very existence."
