You cannot go on “seeing through” things for ever. The whole point of seeing through something is to see something through it. It is good that the window should be transparent, because the street or garden beyond it is opaque. How if you saw through the garden to? It is no use to “see through” first principles. If you see through everything, then everything is transparent. But a wholy transparent world is an invisible world, To “see through” all things is not the same as to see.
