Metaphysics and Memory

I have studied a piece of my work, a drawing partly cut, and it is giving me some thought about the parts of it that remain ’empty’, the parts that are liying behind the cut, where that part of the drawing once was. Is it possible to develop this part of the drawings, to expand on the empty sections, to give the viewer the possibilities of filling the blank space with meaning? Simple but effective changes. It is the same effect of the white in my windows. I am asking myself also, ‘How does my idea of time relate/exist to my ideas about the spaces I draw?’ Is it expansion or contraction of time and space? Or does the whole thing oscillate?
