The word exists is a strange word. You seem to take exists to mean exists to the sense of sight,  yet circles are purely conceptual entities, therefore they only exists to the mind.  Two dimensional shapes are not perceived, nor are 1 dimensional vectors,
 since in the three dimensional world of perception they have no thickness.  PI likewise is purely conceptual,  It is the ratio if two conceptual entities, a circle and its diameter.  To Plato these conceptual entities have a higher form of existance








perceptual entities.  Could we relate to the world at all without the conceptual blueprint of ideas.
