  Conscious perceptual experience is often said to be transparent, or in G.E. Moore's (1922) phrase “diaphanous”. We transparently “look through” our sensory experience in so far as we seem directly aware of external objects and events present to us rather than being aware of any properties of experience by which it presents or represents such objects to us. When I look out at the wind-blown meadow, it is the undulating green grass of which I am aware not of any green property of my visual experience. (See the entry on  representational theories of consciousness.)  Moore himself believed we could become aware of those latter qualities with effort and redirection of attention, though some contemporary transparency advocates deny it (Harman 1990, Tye 1995, Kind 2003).
