“A mote it is to trouble the mind’s eye.”1
Words spoken by Horartio to describe Hamlet’s father’s ghost. In this Shakespearian play the ghost is seen but not believed and one is left to wonder if it is just the seeing of it that makes it real – its existence totally dependent on the desire of the viewer to see it. The ‘mote’ or speck of dust in the eye of the mind of the beholder both creates the illusion and convinces us that what we see is real. Something just out of the corner of our minds eye, those little flecks magnified by our desire to see more clearly. Yet the harder we look the more blurred our vision becomes.
